but functioning with acute abdominal pain.

CT shows a large pseudoaneurysm in the region of the cordile/g about four or five centimeters angiogram underwhelming but for those with experience we know this can have severe clinical consequences. The point here is to show that this pseudoaneurysm is between the superior and inferior pancreaticoduodenal arcade seen here magnified. So it's important to investigate the supply to this pseudoaneurysm

from both north and south. Here is after coil embolization of the superior pancreaticoduodenal arteries and then don't forget to investigate the southern route which shows continued hemorrhage, and eventual coiling of that as

different patient this is an unrestrained passenger in a motor vehicle accident now that you are all

experts in looking at this CT you can see on the right side of both of those images is the spleen you can see that darker grey areas within the spleen that's bad it should look more like the the the lighter parts

and actually all the grey are on the outside is all blood or fluid in the abdomen so this is a bad laceration probably at least a grade four splenic laceration but again this was a hemodynamically stable patient all right

and here's what we saw this is the angiogram you can see the splenic artery and you can see they're kind of diffuse abnormality of the spleen it just doesn't look right under normal circumstances it just look like branches

on a tree and what we're seeing here is just kind of splotchy looking splenic ranked them up so that's not normal we just want to give it a chance to heal this is the scenario we might do a proximal splenic embolization where

we'll go in and we'll basically put a plug or some coils right at the origin of the splenic artery and I love this picture because what it shows is why we do this philosophically what I want you to notice is on the image to the left

you can see the coil right there right if you see the abrupt stopping of the splenic artery and then what you see are all those vessels going up towards the top of the picture those are arteries that are supplying

the stomach it's the left gastric artery some other vessels that then go through vessels we call the short gastric arteries and what you get is is the reconstitution of the splenic artery so on the image to the right all the way on

the right side of the picture those branches that you see are within the spleen so even though we plugged up the splenic artery right at its start the spleen is able to get blood flow through those collateral vessels all right so

that's our goal that's what a proximal splenic embolization is trying to do we just want the spleen to heal a little bit and reality what we want to do is these patients are usually fine we just don't want them to go home and have a

delayed rupture of their spleen because that's something many of us probably don't appreciate if someone has a splenic artery injury or splenic injury and they're doing fine and then we send them home there is an incidence of

delayed rupture of the spleen and what we know through lots of good papers is doing these proximal embolization procedures helps to reduce that risk of delayed splenic rupture so that's what we're trying to do there all right so

plan as well so I wanted to talk a

little bit about imaging I know with our residents and fellows and radiology that's all we do is talk about the imaging and then when go on to IR we talked to them about the intervention but I think it's important

for everyone in this room to see more imaging and see what we're looking at because it's very important for us all to be doing on the same page whether you're a nurse a technologist a physician or anybody else in the room

we're all taking care of that patient and the more information we all have the better it is for that patient so quick primer on a PE imaging so this is a coned in view of a CT pulmonary angiogram so yeah sometimes you'll see

CTS that are that are set for a pulmonary artery's and you'll see some that are timed for the aorta but if the pulmonary arteries are well pacified you're gonna see thrombus so I have two arrows there showing you thrombus that's

sort of blocking the main pulmonary arteries on the left and right side on the patient's left so the one with the arrow that is a sort of very classic appearance of an intro luminal thrombus you can see a little rim of contrast

surrounding it and it's usually at branch points and it's centered in the vessel the one on the right with the arrow head is really at a big branch point so that's where the right lower lobe segmental branches are coming off

and you can see there's just a big amount of thrombus there you can see distal infarct so if you're looking in the long windows you'll see that there's this kind of it's called a mosaic perfusion but it also what kind of looks

like a cobweb and that's actually pulmonary infarct and maybe some blood there which actually will change what we're gonna do because in those cases freaken we will not perform PE thrombolysis it's also important to note

that acute and chronic PE which we're here to talk about today may look very similar on a CT scan and they have completely different treatment methods so here's a sagittal view from that same patient you can see the CT scan so

between the arrow heads is with the tram track appearance so you'll see that there's thrombus the grey stuff in the middle and you'll see the white contrasts surrounding it and kind of like a tram track and that's very

classic for acute PE and then of course where the big arrow is is just the big thrombus sitting there here's another view of a coronal this is actually on a young woman which I think we show some images on but you can see cannonball

looking thrombus in the main pulmonary arteries very classic variants for acute PE and then this is that same patient in a sagittal view again showing you in the left pulmonary kind of those big cannon balls of

thrombus here's some examples from the literature showing you the same thing when you're looking at an acute PE it's right centered on all the image all the way in the left if the classic thrombus is centered right in the middle of the

vessel you can usually see a rim of normal contrast around it and you can see on a sagittal or coronal view kind of like a thin strip of floating thrombus so the main therapies for acute

the take-home point is this that most of the time when we see a bleeding patient we're thinking of embolization we're thinking of going in looking for an

arterial abnormality going as far into the organ that we can embolizing that organ and trying to preserve as much flow to the normal parts of the tissue that we can to preserve the function of the organ today in the back of our minds

we're always thinking about putting covered stents across this but in some ways you realize that's a band-aid right with just you know the arteries that we put those covered sense and we're severely injured and there's always a

chance that flow can work around there so they could be leaks around covered sense so I still think embolization is a bit more definitive than cover stent placement but I find it when a growing number of patients cover sent placement

is definitely an option for these patients so I am here for ask any questions but I can also appreciate that you have a break it's been a long day so I will not get offended if none of you have questions all right perfect

yeah yeah no that's it's the nature so what what he asked here is is that GI bleed cases tends to be unsatisfying because you hear about them and then by the time you get them down to the NGO suite and you

do an angiogram they're negative and it does happen a lot you should know it's the nature of the pathology so what ends up happening is let's be honest I mean a lot of people who work in AI are just like to push things off sometimes so

they get a call for a GI bleed or they say oh let's get a bleeding scanner let's get a CTA by the time you see them at 6 or 7 hours later and they're negative because they've stopped bleeding and that's the nature of the

pathology so my personal philosophy is to get at these patients as quickly as I can I think it's just a better way to go if someone thinks they're bleeding the faster you get at them the greater the likelihood is that you're going to see

some some abnormality there and I think that's been true I think as we start to do these faster we're seeing more positive cases it might be nice to have a CT angiogram or a bleeding scan but I think by the time you see them after

that you know they're negative it's not anything you're doing wrong it's the nature of the pathology it's intermittent bleeding and that's what happens some people feel like they can give TPA to some of those patients like

they'll go into the SMA they'll give some TPA which let's be honest right all of us are saying what the hell that seems like a horrible idea and I agree with that I mean if the body has stopped the bleeding on its own why in the world

would I give a drug to dissolve the clot to start them from bleeding again so I don't like that idea but there are people that will do a bleeding you know kind of a challenge with TPA to see if they can open up something to identify

the bleeding to then go back in and embolize it I think my bias is coming through and how I answered that I don't know we don't used to out for that anything else yeah I think gelfoam has its place I think

gelfoam has its place for things like postpartum hemorrhage or you know some maybe some trauma and a younger patient but gelfoam in general is something that you're giving over a much larger area of territory so I think if you can identify

a bleed and just coil that particular bleed you're doing a better service for the patient but all these are obviously good hey let's see it in a lecture case in real life you may or may not see something so obvious and I think if you

have a patient that had some bleeding on a CT scan a bad pelvic fracture and you just didn't see it in geographically but you know something's wrong giving gelfoam is a legitimate thing to do all of us equate gel foam with a

temporary embolization effect the truth is we're not we're second guessing that a little bit and a lot of people who use gel foam feel that the extent of the inflammation that we get when we use gel foam is probably so great that even

though the embolic agent itself may go away the occlusion that we caused with the gel foam probably stays around longer than we think so I'm not so sure it's a it's a great temporary agent but I would say which we mostly limited to

postpartum hemorrhage patients yeah what's the cause of it usually it's a uterine rupture it's a vessel rupture I've gone three more questions than the leadership guy which is great anyone else yeah

well there's no doubt about it I think that IR is moving towards radial access I think 10 years from now the vast majority cases are going to be radial access it's the one area of our practice that I think I'm starting to feel my age

in I mean you know I think and you probably may see this at your own centers I think people that have been doing ephemeral access for a long time we're just more comfortable with that one of the issues that we're facing with

radial access as we begin to think about doing more radial access at our place is that we may be comfortable with it but places like the ER and the ICUs and the other areas that we're sending our patients back to are not yet skilled

enough as to how they manage those patients so our nurses are very frequently the ones to say I don't know if they're ready for us to send a radial access patient to whichever floor we're talking about so we have some work to do

to in service those the nurses on those floors as to how to take care of those patients first and until we do that I think we're going to be limited more to outpatient work with our radial access all right guys enjoy the rest of the

meeting [Applause]

finally intraoperative considerations positioning for comb bean tpz photo

sensitivity EKG and lab draws and noting the time of tpz injection so i wanted to say a little bit about comb beam all right who has comb beam at their facility just a few less okay comb beam is medical imaging technique consisting

of x-ray computed tomography where the x-rays are divergent forming a cone the scanning software collects the data and reconstructs it producing what is termed a digital volume composed of three dimensional voxels of anatomical data

that can then be manipulated and visualized with specialized software on the left is a standard floral image and on the right is the comb beam so the red shows the vascular angiography the blue is a tumor and the yellow is a feeding

artery to the term or so dr. Abuja lays a B today is heavily involved with research so the procedure room with Combee was exclusively constructed for her so positioning for comb beam I believe

to be the bigger challenge initially comb being requires the patient to have their arms up high and using comb beam technology increases the procedural time it would be difficult for the patients to maintain that position and keep still

without anesthesia we started clinical trials with nurse assisted moderate sedation and soon learned it was very difficult the majority of our HCC embolization --zz are done with with sedation but we're

now using anesthesia for all of it so the lead in this case was Tom the radiology tech which assisted with the placement of the anesthesia equipment and patient positioning our anesthesia personnel are not only out of their

comfort zone in the I are sweet but unfamiliar with tpz trial and how the comb beam equipment rotates completely around the patient the patient is wearing two sets of leads one for anesthesia and the other for research

the leads are radio translucent to reduce artifact and imaging keeping the lid lid lead in the department took some getting used to one set got thrown away one set was found up in the ICU one set was on the

anesthesia equipment it was hard keeping track of our special equipment there so the pulse oximetry and blood pressure are on the lower extremities for cone beam again to avoid artifact and imaging when we first

started using cone beam the nursing staff administering sedation were disconnecting patients from monitoring so there were short interruptions with viewing vital signs it became risky and time-consuming to do

so during the procedure one set of EKGs triplicates are done just prior to tpz injection so the treat the EKG triplicates are basically they're two minutes apart in sets of three and lastly having to keep the tpz in a brown

bag and protected from light during the transfer nurse to position there's the photo on the left upper corner doctor busy day basically draws a tpz through a three-way stopcock under a sterile towel

while the nurse keeps the syringe in the brown bag poking a hole in the bag just to NIF to just enough to expose the tip of the syringe and attach it to the three-way this way the tpz is protected from light these reminder adjustments

however they were difficult from the standard and it took time for all the nurses and techs to adjust all right so this here is just a group photo Tom I've got Tyler on the right Thanh our technologist and ELISA and myself so I

thought this was a good photo to represent radiology many specialties consult two IR but it just isn't quite known yet by the general population and surprisingly by the medical staff as well there is a quote by dr. Rosa be

published quote the reason the public doesn't quite understand is we deal with so many disease entities and so many body parts it's hard to brand us unquote so I don't know if you guys were aware but interventional radiology is now its

own medical specialty so hepatocellular carcinoma is a primary malignancy of the liver and now the third leading cause of cancer deaths worldwide with over

patient female patient who has the sudden onset of upper abdominal pain here's the CT we did all these cases in one day it was crazy it was terrible so so here's a big hematoma a big peritoneal hematoma you

can see it anterior to the right kidney you can see the white blob of contrast right in the middle of the hematoma that's a pseudoaneurysm or even active extravagance um less experienced people would probably say it's active

extravagant I think most of us would prefer that it be called kind of a pseudoaneurysm this active extrapolation would be much more cloudy and spread out this is more constrained and you can see on the

coronal image you get a sense that there's that hematoma same type of problem all right is there more imaging that we can do to figure out the next step again I said earlier earlier in this lecture

that sometimes we use CTA now sometimes a CTA is worthwhile I do find that for a lot of these patients I think we're getting smarter and we're doing CTAs right at the beginning of this whole thing you know when a trauma

patient comes in we're getting CTAs so we can max out the amount of information that we get on the initial diagnostic imaging here's what we're seeing on the CTA and in this particular case I think it's pretty clear that you can see the

pseudoaneurysm arising from what looks like a branch of the superior mesenteric artery so this is just an odd visceral and Jake visceral aneurysm which looks like it probably ruptured I don't have an explanation for it led to a big

hematoma here's what that is and now we're gonna do an angiogram the neat thing is it just perfectly correlated with a conventional angiogram so here's our super mesenteric angiogram all right the supreme mesenteric artery

on the first image to the left is that vessel going downward towards the right side of the screen all those vessels coming off are really just collateral vessels going up to the liver through the gastroduodenal artery again that

left one looks pretty good it's not until you see the delayed image on the right that you see that area of contrast all right so that's the finding that correlates with the CT scan all right here we're able to get in there you put

a micro catheter in that vessel alright the key next step for this patient as I mentioned earlier is the whole concept of front door and back door so here we're technically in the front door the next thing that we do is we put the

catheter past the area of injury and now we embolize right across the injury because remember once you embolize one thing flow is gonna change we screw it up body the body wants to preserve its flow if we block flow

somewhere the body's gonna reroute blood to get to where we blocked it so we want to think ahead and we want to say okay we're blocking this vessel how's the body going to react and let's let's get in the way of that happening that's what

we did here so we saw the pathology we went past it we embolized all across the pathology and boom now we don't have anymore bleeding and the likelihood of recurrence is gonna be very low for that patient because we went all the way

across the abnormality and I think from

symptoms we've talked about the location so what are the options now I've kind of scared everybody enough said okay fine if my periods are last in more than

seven days if I have pain with my periods if I have clawed if I have painful sexual intercourse back pain hydronephrosis and sciatica all kinds of these little things then maybe I could be having fibrous what do I do about it

and there are several options obviously I'm here to talk about embolization but because everybody in this room is talking about informed consent every day we have to be able to talk to our patients about what are the options and

I always try to start off with the simplest of options doing something or doing nothing remember this is not a cancer this is a benign disease and it's important that we explain to our patients that they also have the option

of doing nothing although doing nothing has some consequences right every action has a consequence and the consequence of doing nothing includes continuing to have your disease continuing to be sick and abnormal and if you chose to do

something let's say a surgical option then obviously you can have hysterectomy or myomectomy now Maya met to me is just where you're cutting out the fibroid hysterectomy is taking the whole uterus out and then there's a whole series of

other things whether you're having it laparoscopically or transvaginal Eeyore I'm here to talk about uterine artery embolization we offer all of these options to our patients though because it's important that we at least know

that there are other options to be done

patient who presents with rectal

bleeding he's had a transfusion and this is the angiogram so it's gonna be a lot easier people volunteer so who wants to say what they see what do you say what do you say show me tell everyone what you say well there's two

slides the first one you see just a little bit of blood and on the second slide you can see where he's really bleeding all right so these are the same the same patient same angiogram so one thing you guys should realize if you

don't know this already about an angiogram is an angiogram is a series of pictures over time good job by the way so a series of pictures over time so it's not just one image and the analogy I like to give is if I take my kids to

Disney World right I can have that picture of all of us in front of the castle with the Mickey hats and everyone's smiling but like one second before this one kicked that one and one second after this one smacked the other

one in the head and they're all crying but I got that one picture an angiogram is that situation it's a series of pictures over time so while you may look at that first picture on the left and maybe not see so much going on what you

should appreciate on the right is that big blobby thing of contrast over on the right side all right now what that means is that there is blood pouring out of that person's vessel all right this is a mesenteric angiogram it's a superior

mesenteric artery angiogram we put a catheter in by the groin from the groin we went into the SMA and we took some pictures and this is what we're seeing and we're appreciating hopefully that big blobby thing on the right all right

so this is what we'll call a lower GI bleed all right the patient's essentially crapping blood that's a lower GI bleed all right so given that just another hint this kind of implies that we're gonna talk about upper GI

bleeding later all right just so you know so there's lots of different causes for lower GI believes there's diverticular disease there's angiodysplasia switch our small malformations of the blood vessels

there's a ski mcdowell there's patients who maybe had radiation therapy for different cancers can be predisposed to bleeding cancer itself can cause bleeding and different inflammatory diseases like either infections or other

diseases can as lower GI bleeding now how do we work these patients up well usually I would think that most of the time these patients have hit an ir suite they've probably had a colonoscopy first and a

colonoscopy is really the first line used to assess what's going on with a lower GI bleed it's not that easy to do it's difficult to prep those of you who resolve this I am and have had a colonoscopy know that it's better when

you prep before the colonoscopy and if someone comes in with a lower GI believe they haven't been adequately prepped that makes the colonoscopy very difficult the other thing is remember you're going from the bottom up into

colonoscopy and you have blood coming at you in someone who is experiencing a lower GI bleed and that essentially means it's difficult to see so many times the colonoscopy is not really able to tell us what we need to know I would

say the next thing that usually happens is some type of imaging now of a sudden the patients are coming to radiology and what you may have is any one of three different options you might have a nuclear medicine bleeding scan you might

have a CT angiogram you might have a regular old conventional angiogram and for those of you saying who cares what's the difference just take some pictures the big difference is that the amount of bleeding that it takes to see it is

different for each of those exams so the most sensitive exam is the nuclear medicine scan that's going to pick up the lowest rates of bleeding a conventional angiogram is the worst scan we can do for GI bleed or worse imaging

we can do because you need a lot of bleeding to see it so when we saw when my friend here picked up the the blobby thing on the right would that bleed that's a big bleed like we can look at it and say aren't these really pretty

pictures but when we see it and you see that kind of bleed you have to realize that's a lot of bleeding to see it like that so our antenna has to go up and we have to start moving a little bit CTA is kind

of right in the middle and actually a lot of people are turning now to see TAS I'm not personally a huge fan of that because I think it's a waste of time and contrast in my opinion I think a CTA for GI bleeding is a way if I can translate

it is I don't feel like doing that case right now so I'm gonna get a CTA and we'll figure it out later all right that's that's my language for a CTA but in my opinion you know it has some value how do we treat them well if

you can see on colonoscopy then you can potentially treat it with colonoscopy and there's different things that they can do with their scopes obviously if there's more diffuse disease they can remove part of

the bowel that's that's a problem and then of course the answer is embolization exactly so here is the picture from our embolization procedure and what do you see all right I won't pick on anybody yet basically what we

did was you can see over there you can see the shade of our angiographic catheter there's a micro catheter now passing all the way into the actual vessel that's bleeding and now when we do an angiogram you can actually see the

vessel that's bleeding now conventionally in the old days for those of you that have been doing this for a while you probably are used to living in a world where it's not great to embolize lower GI bleeds it's better to embolize

upper GI bleeds and lower GI bleeds and the reason why is because there's less collateral flow so if we block up a blood vessel we essentially kill everything beyond where we blocked it up because there's no alternative routes

for blood to flow all right in this particular case you can actually see that long stringy thing going right to the bleed and here we were able to get into that single vessel and kind of see it right there the long think heading

towards 4 o'clock and when we embolize it you can see we put coils in there and blocked it up so the only thing we embolize there is the blood vessel going to the abnormality the risk of ischemia is low and the clinical efficacy is high

but if you can't make it all the way out there if we embolize let's say right there that entire loop of intestine would be infarct it and that would be bad so we always have to think about that when we're embolizing GI bleeds all

similar but similar story an older patient who presented for a biopsy of a right renal mass now sometimes it's a skiing accident sometimes it's a car accident sometimes it's us that causes

these problems so here's a patient who came in for a biopsy of a renal mass here's the CT scan hopefully you can appreciate that the patient is face down or prone on this scan this by the spine is on the top side you can see our

biopsy needle going into a mass in the left kidney excuse me the right kidney and now this is the she comes back later because of some pain and now in a manner that's similar to what you said earlier on that first CT scan you can now see

the right kidney is pushed forward by a very large retroperitoneal hematoma so this is probably a post biopsy bleed this doesn't happen very often in fact as someone who does kidney biopsies once or twice every day I'm shocked that this

doesn't happen more often we're sticking big needles into vascular organs or vascular masses it's amazing that we don't have more patients come back for this it only happens about 2% of the time and usually people who have these

types of risk factors are at risk for this type of bleeding after a biopsy but we can do is we can go in do an angiogram and again I want you to just appreciate look at the picture I think everyone hopefully can see on the bottom

of the picture there's this active extrav enough contrast from the lower pol renal arteries all right lo pol renal artery and that's bad if it's great in a lecture because it's very easy for everyone to see but the reality

is it really signifies very significant bleeding and that's what everyone here should appreciate if you're managing the trauma patient or the bleeding patient if you see if this Cleary this clearly means everyone's got to move a little

faster to address it because this is a bad bleed but the great news is that we have the technology now to go all the way into the renal arteries or frankly the arteries of any organ get very far distant land just embolize it and so

look how far we got here for this patient we took care of it this patients kidney function didn't pump an inch because the reality is there was very little impact on the normal parts of the kidney so that's the goal if you guys

work with people who say oh we don't have to get that far out just throw some coils you know near the origin it's fine it'll accomplish the same goal but at the same time they will have killed half of the patients kidney so it is always

worth making some effort to get as far as you can into the organ that you're treating but at the same time you don't want to take an hour to do that because the patient's bleeding pretty heavily and you have to address it so that's our

goal during these procedures next case

let's move on here is another patient who took a fall skiing we see a lot of these patients up in upstate New York and they presented with severe left-sided abdominal pain and here's the cat scan

all right who's up for it what do you think what looks bad you look like you're into it what do you think yeah the right the bottom right-hand side of the picture should be spleen and it just looks like a big pool of blood that's

pretty good you did pretty good spleens a little higher so we're gonna presume spleen is there Graham this is just one image one slice through the picture through the body so we're just not at the level of the spleen but that's the

kidney that's exactly right that white thing on the right side of the image of the patient's left side is the kidney and the one thing I'd like everyone who appreciates that doesn't look at all like the other side all right so when

you look at a cat-scan like this you want to look for symmetry that's really important all right that's the cool thing is we're kind of meant to be similar looking on both sides of our body and in this particular

case you can see that the left kidney has been pushed way forward in the body compared to the right side and there is a kind of a hematoma sitting in the retroperitoneum posterior behind the kidney that's bad

the other thing you should notice is if you look at that left kidney you notice that white squiggly line that doesn't belong there okay that's contrast that's not really constrained inside an artery that's extravagant of

contrast that's bad all right we don't want to see that all right again there's a grading system for renal trauma and you're gonna hear people talk about grade 1 2 3 4 injuries all right obviously as the number gets higher the

extents of the injury gets more significant all right so again here's that picture think you can appreciate that it's at least a grade 4 laceration of the kidney so we went in and we did an angiogram now we can watch these

patients we can surgically manage them by taking out their kidney in some ways that's the easy part excuse me it's a lot more elegant to try and embolize these patients if they're hemodynamically stable and can take you

know getting to angio and doing the case now in general we do embolization for patients with lower grade injuries and usually penetrating injuries a penetrating trauma that's seen on CT I think this is something that's changing

I if any of you work at high-volume trauma centers the reality is that we're doing more and more renal angiography for trauma than we used to because it's just becoming a more accepted thing for us to

be doing that all right so here's the angiogram and again I think you can notice it really correlates very well to what we saw on the CT scan you see that first image on the left and on the delayed image you see that that kind of

poorly constrained contrast going out into space now we were never really quite sure what this was if it was extravasation or if it was potentially an arteriovenous fistula with early filling of a renal vein regardless of

which it's not normal all right so what we did was we went in and we embolized and I only included this picture because I'm a big drawer during cases so when I'm working with a resident or a fellow I like to really

lay out our plan on a piece of paper and try and stick to the plan and this particular picture look really good so I included on the lecture but basically you can see that the coils the goal here for any embolization procedure

when it comes to trauma is to preserve as much of the normal organ as we can and to simply get you know to the source of the bleeding and to get it to stop and that's what we did there so what you can appreciate on this is kind of the

renal parenchyma or the tissue of the kidney is largely maintained you can see the dark black kind of blush within the kidney and all that really stands for properly working kidney all right and yet we embolize the pathology so that's

our goal here's a similar patient not

so my name is Paul I'm one of the nurse practitioners from UCI Irvine healthcare and what am i one of our minerals in there is basically working on patients for consultations doing the patient rounds writing notes ordering labs etc we also have several clinics that we run

at UCI Medical Center involving patients needing consultations for Libra direct therapies ablations and so forth and one of the more recent clinic that we started running is basically treating patients with BPH and so what we would

know inspiration is basically treating and regarding their symptoms and the procedures pretty much called a prostate artery embolization so the main purpose of this patient excuse me the main purpose of this

topics is basically to provide the general information of what the procedures are about illustrating indications risk and to hopefully help our nursing staff to better take care of these patients sorry so first and

foremost I just wanted to thank my team UC Irvine for allowing me to take some time off of work and enjoying Austin and its many food and object and and allowing me to speak to you guys a little bit about prostate ammo on our

pitchers basically you can't I don't know laser printer but our physicians dr. Karen Nelson she's one of our chief of IR dr. Dan through Fernando dr. Nadine a bitch day and dr. James Castro thesis

he's got daughter Kat Reese is our main doctor that does most of our process embolization our excellent iron nursing team and of course my fellow nurse practitioners who is holding the fort back home Pamela and Takara and watch

and Lou sorry but so our objectives for discussions basically to illustrate the indications and benefits of prostate artery embolization we're going to go over the side effects and risk complications associated with this

procedure and also recognize the value of nursing care going starting from the workup leading to the proper process in trot process and post procedure care sort of a brief outline of what we're gonna be

talking about we're just gonna go over the basic fundamentals of BPH as well as the treatment for PAE and the second portion of this lecture is going over how we walk patients up in clinic what we tell patients and we're gonna go

through the proper care and drop care ask well ask the post-op care and we're going to go through a couple of cases in there it's just to describe to you guys how we care for these special population

happy to take any questions or in

ultrasound we don't usually use contrast but one of the procedures were doing for the treatment management of a pulmonary embolism is the ultrasound assisted Rumble Isis do we need contrast so for the thrombolysis is the catheter itself

so you still need to give contrast two to do the procedure but while the catheter is running you don't need to give any contrast four for that is that what you're we don't usually use contrast for ultrasound but

all right when you're treating how will you know that it sliced the clot is less what you frequently do is check the pressures so that catheter allows you to check the pressure and so once you start a patient so you do a pulmonary

angiogram which requires contrast and you put the ultrasound assisted thrombolysis catheter in the eCos catheter then after 24 hours or 12 hours you can measure a pressure directly through that catheter and if the

patient's pressure is reduced you don't have to give them anymore injections yeah and if we are using ultrasound for treatment is it possible to do it for diagnostic purposes No so not for non the prominent artists for

diagnostic imaging unless you're doing an echocardiogram which is technically ultrasound in the heart but for treatment otherwise you need you will need to inject some dye oh thank you

hi I'm Katrina I'm NGH I have one more question okay for your patients with chronic PE do most of them begin with acute PE or if they very separate sort of presentations that's that's a great question so all of them

had acute PE because you can't have chronic without acute but a lot of them are not ever caught so you'll have these patients who had PE that was silent that maybe one day they woke up and had a little bit of chest pain and then it

went away couple days later they thought they had a bronchitis or a cold and then you find out five years later that they had a huge PE that didn't affect them so badly and then they have these chronic findings they usually show up to their

family practice doctor again with hey I just can't walk as far as I can I have a little heaviness they rule them out from a heart attack but it turns out that they have CTF so you you all of them had a Q PE but it takes a lot of time and

effort to find out whether they truly have chronic PE so it's usually in a delayed fashion thank you all right well thank you guys again appreciate it [Applause]

all right another patient 52 year old patient ATV accident we get a lot of

lunatics on ATVs in our area and they presented with severe back pain here's the cat scan you see that white thing kind of in the back on the right side it almost looks exactly like that liver one I showed you two patients ago the

difference is that that's not conscious that's a part of the patient's bone that's the spine that fractured off and is now sitting in the middle of a big hematoma so that's why my kids don't have ATVs all right so basically that's

a big retroperitoneal hematoma due to a transverse process fracture all right in light of an ATV injury here's the angiogram now look at the picture on the left first that's an aorta gram you see the renal

artery at the top you see the bifurcation of the aorta kind of in the middle going down to each side and maybe just on that first image you see a hint of maybe some cloudy extravasated on the left side of the spine excuse me the

right side of the spine the left side of the image now remember I just I know I keep hammering this point home but you need the delayed image to make the diagnosis that's normally going to tell you if there's a real problem and on

that image on the right which is a bit more delayed you can see the extravagant Rast next to where the spine was that's an injury that's a lumbar artery injury and as we get closer all right we put a micro catheter in that lumbar artery now

you see the extraction and the question always comes up how much of that space do we need to fill that's an abnormal space that's just receiving all the blood that's leaking out of the artery and basically we don't have to fill all

of it we try we try to but it takes a lot to fill that up so we'll go in there you can see we put a lot of coils in this space and then we started packing coils back into the artery that was injured and I know it looks really big

on that image but if you go back into a finally orna gram you can appreciate that we were in a very small artery there but the technology that we have now allows us to get very far into very small arteries and that I think is

what's changed over the 20 years that I've been doing this at the very beginning of my career we wouldn't think about doing any of these things since we didn't have the tools to get that far out we had to

embolize these vessels very close to their origin and that led to a failure rate and an adverse injury rate that we don't see now that we can get this far out keypoint another case we have an older

patient who did not come from the street so if you've been here for a few years

you've heard me talk about you know some of my friends this is also one of my other friends who has large fibroids but her fibroids were so big and they were not all very vascular and so I sent her to have surgery and she ended up having

a hysterectomy with removal of her cervix because of abnormal pap smears but her ovaries were left in place so our path forward after doing this procedure from 1995 a procedure that is not experimental a procedure that has

had a lot a lot of research done on it more research than most procedures that are done surgically or by interventional radiologists I'd say that it would require a partnership it is true that we can see patients on our own and we can

manage mostly everything but at the end of the day uterine artery embolization is still a palliative procedure because we don't know what causes fibroids to begin with and as long as the uterus is still there there's always a chance that

new fibroids will come back so in your practice and in mind I believe that a path forward is a sustaining program embolization program which is built on a relationship with the gynecologist that yes

I am as aggressive as any other interventionist that is out there but if this were my mom and that is my usual test for things I would say that where we would like to position ourselves is in the business of informing the

patient's as much as possible so that they can make an informed decision and that we're asking our gynecology partners to do the same is that if you're going to have a hysterectomy for a benign disease that you should demand

and we as a society and you as your sisters keeper should be asking for why am I not eligible for an embolization so si R is actually embarking on a major campaign in the next year or so it's called the vision to heal campaign and

it's all around providing education for this disease stage what I like to tell our patients and I'm almost finished here is when I talk to our gynecologist and to techs and nurses as well I said woody woody what should I expect right

that's what they want to know when I send my patient to you what should I expect and I say that what you should expect that Shawn and myself we're gonna tell the patient everything about fibroids we're gonna talk to them about

what the fibroids are the pathophysiology of it the same things I told you we're gonna tell them about the procedures that treat it we tell them about the options to do nothing we talk about all of the risk and the benefits

of the procedures especially of fibroid embolization and we start the workup to see if they're an appropriate candidate when they're an appropriate candidate we communicate with them and their OBGYN and then we schedule them for their

procedure in our practice there are a few of us who send our patients home on the same day and we let our patients know no one is kicking you out of the hospital if you can't go home that day then you'll get to stay but

most of our patients are able to go home that day and then we see our patients back in clinic somewhere between two and four months three months and six months and we own that patient follow-up their visits and after their year we have them

follow back up with their gynecologist and so that we're managing all of these sites and it comes back to that new again may not be so new for some of the people that have been doing clinical IR four years that shift that we own these

patients if you're a nurse in this room these are our patients these questions need to be answered by us in our department we do not believe that these patients should be calling their gynecologist for the answers to that

like what should I be doing right now should I be taking I haven't had a bowel movement and like that is something that we answer we're the ones that are given them the discharge instructions and we set them back up for their follow-up so

so we're just gonna like hop over to the clinic side and kind of discuss how we work up or what are the things we look for when we see the patients in clinic

so a lot of patients are referred to us by urologist so we have to have a urology on board to to better take care of this patient we can't treat this patient you know by ourselves so a lot of patients are referred to us by our

neurology team if they don't have a urologist we have to refer to them to erosions first before we can even work them up or PAE so we won't make sure that patient you know doesn't have any underlying cancer that we know of so we

want to make sure that we check their PSA levels because this high high patient can ask actually I predict a decent progression and actually our risk for acute urinary retention you want to make sure that you get

urinalysis a lot of patience wet with lots is not only due to pph you could also be secondary to UTI or if patient has some type of bladder tumor or bladder disorder so it's kind of good to know to understand some of the lingo

that urology uses so once they see the urologist they do some your dynamic studies and one of the popular ones are these non-invasive studies called euro flama tree and the post-void residual do you offer the Euro excuse me you heard

from a tree usually we will measure the flow rate and the volume of the patients so what they do is they they would pee in this special funnel and the final obviously they go in private but this final is connected to some machine that

can actually measures how fast and how much their voiding and so normally it's about 25 miles per second but if it's anywhere less than 13 to 15 it can suggest obstruction and use the obstructions usually due to BPH some of

us a very low flow rate such as like say less than ten or six you have you want to be a suspicious of some type of you to neutral structure after they do that usually what they'll do is they take a post void residual is basically scan so

they'll put that little probe above the bladder and they'll see how much is left in a bladder if it's 150 that she usually indicates in complete emptying someone who has greater than 200 that may suggest patients having some type of

bladder dysfunction so a lot of its patients to us at least woke up with some type of imaging and the ones that at least our physician selects is the MRI patient do get a CT angiogram which can also evaluate the pelvic Anatomy and

arteries however the process the mr process actually gives a better illustration of the prostate a tissue to see if there's any suspicious for cancer for example you can also display the president atomy and characteristic up

the gland so most patients do get MRI or at least we get them to get MRI to measure the actual volume in literature they will tell you that a patient can get a trance rectal ultrasound but I'm not sure how many

guys in here would like a probe stuck up their butt to get to get their prostate measured so unless you wanted to get pissed at you just supporter I am right so when we see the patient you obviously want to review their HMP more

importantly you'll want to check their comorbidities there's social history whether it is smoke or not because they're gonna that's gonna have an impact on how we stay patients and how you can predict their anatomies

obviously someone's died who is diabetic or who has a history of smoking you could expect for them to have a greater degree of atherosclerosis and again the first thing that we would get the patient why we walked in is we go in

that scoresheet the IPSS score and so that's gonna give us an idea of how bad this symptoms are so if they come in to us with a score of say you know they're mildly symptomatic I'm not sure how much to pee a procedure with would help them

because how much more lower can we get their scores down so a lot of patients we would treat are in the moderate to severe category and their quality of life score should be for the most part will be about three or higher you also

want to make sure the trusted results since this is Andrew Graham procedures you will make sure that they have a pretty decent renal function patients with lots a lot of them may have some degree of renal insufficiency so we have

to be careful make sure we watch that lab value so this is some of the screening criteria that a lot of us may use so patients who I have refractory to medications for the six months someone has a high IPSS core grain 13 or

qualifies score greater than three process volumes gotta be at least 40 grams we sometimes get patients with a high score but they're positive volumes around 30 we usually usually wouldn't treat those

patient because we can't basically treat or shrink the prostate any any lower than that you someone who has an abnormal urine Flo and someone who maybe refractor to medical therapy these are just a list of

exclusion criteria the ones that should my party set out someone who has prostatitis or current approximate infection you definitely want don't want to treat those patients chronic renal failure and relatively maybe coagulation

factors that could be patient dependent sometime sometimes we could optimize them to get this arteriogram procedure and prostate and bladder malignancy also this somewhat also relative we do treat patients with prostate cancer it just

depends on what course of treatment they're on currently so once we had screen the patients and and deemed them to be a candidate we reviewed the patient we review in detail the procedure with the patient so you want

to let them know that it's a our angiogram procedure that will go through the either the growing or sometimes the radio and the procedure itself you can take anywhere from one for one to four hours and sometimes longer depending on

how complicated their arteries feeding the prosthetist more importantly we want to educate them about the side effects okay we have to let them know that a lot of their symptoms might actually worsen during the first few days after the

procedure so if they have the Syria now urinary continence they actually may get really worse especially for the first few days okay we have to go over the complication with the patients that can include a public infection ischemia or

any vessel related complications that pseudoaneurysm or bleeding so we have to basically have a basic knowledge of how do we combat this side effects and these are just some of the list of side effects that

are mentioning or at least we also used a PI radium it helps I guess to numb up the prostate urethra we have to educate the patient that this can change the color of the urine so we always make a note to our patients that if you are

going to take this medication please call us that way we don't kind of shock you and we also know that the change of color is from the pair radium and not from anything else the tripping or oxybutynin

it helps reduce bladder spasm we would normally use it for a patient who go somewhere to Foley our patients would go some Foley tends to have a great degree of bladder spasm Coley's a lot of spatially get constipated for multiple

reasons being better that or they and she is soft and there's also the over-the-counter azem so this is just a sum of the standard medications that we would give all our patients all of them will get about cipro for seven days

we'll give them some type of anti-inflammatory Asia usually is ibuprofen were prescribed 800 a tid if needed anti-acids since it's just to protect your belly or their stomach from the ibuprofen minimum we'll get a stool

softener at least for the first three days or if they got developed loose toast and we would ask them to stop it and the medications for pain that we would get them as Norco just in case and I would say like more than half these

patients don't even need Norco at best they'll probably use ibuprofen you know just to minimize the inflammatory side effects that I get it also helps out with post embolization that sometimes we'll get and I believe so I don't I'm

not sure if I'm messing about post embolization syndrome patient do can get these symptoms and a lot of symptoms can vary they can get some body slug or fever malaise and the degree the symptoms were may bear from patient to

patient and a lot of symptoms are described kind of like a flu-like symptoms and we also want to reiterate a patient that the symptoms are temporary and it should get better over to at least at first week or so so patients on

warfarin we have a lot of patients on warfarin for whatever reason whether they had a recent cardiac intervention we want to assure that we stop those medications at least before the edge ground procedure so it's very important

that you have a good rapport or whoever and have prescribed him the coumadin whether it's a cardiologist or the surgical team and a lot of dissipation may need to be crossover outside like a short-acting

anticoagulation such as Lobo Knox at least in our practice we ask the patient to this condition discontinue your aspirin unless they're you know they have a recent cardiac intervention we may leave it leave them

on aspirin metformin as very important since we did it is a natural procedure we want to at least hold have the patient hold the metformin the morning of the procedure and maybe a couple of days after and someone who are

allergic to contrasts we will make sure that we're prepared to premedicate a patient and also be prepared in case there's a severe reaction and the pre medication as we know will give them some type of a standard metal prednisone

will they'll take it like twelve seven or one hour before and they also gets unbearable and preoperatively or one hour before the procedure and during the clinic we also determine the level of anesthesia so since this procedure

usually takes a long time we always get it with our anesthesia team is just more for patient comfort it's not really for pain okay I couldn't imagine laying a table for several hours at the time so we all shop anesthesia on board just

really for patient comfort so we're just

right now here's a different case is a 49 year old male who presented to the emergency department after vomiting a lot of blood vomiting was the key word there it's going the other direction so that's an upper GI bleed all right and

when we talk about upper GI bleeds there's a lot of different causes for upper GI bleeds the most common are ulcers but there's mallory-weiss tears of the esophagus there's just esophagitis or gastritis

there's different cancer vascular malformations fistula is varices which I'm not going to talk about but varices on the venous side in a patient with portal hypertension these are all causes of upper GI bleeding now

once again we might treat them medically we might look at them with endoscopy and potentially cauterize something embolization usually is used when and when endoscopy is not successful all right or certainly surgery but an upper

GI bleeds embolization is a lot more attractive of an option all right so here's another picture what do you think you up for it nope you turned me down all right who wants to who wants to tell me what they see how about you how about

you guys you can team up together what do you think so what do you seeing so let's look at that together so this is a seal EF is an anagram of the celiac axis you want to think it through you want to volunteer you see a filter we don't care

about that yeah all right that's fair so you see the catheter going up right in the middle and it's going right into the celiac axis all right what I want to draw your attention to is right in the middle of the screen a little bit over

to the left is again a blobby thing all right that's extravagant of contrast and the vessel that that's coming off of is the gastroduodenal artery so I want you to see that if you look at the catheter you

can see the shadow of the catheter right up going up from the bottom that's going into the celiac axis and the big vessel going over to the left side of the screen is the proper hepatic artery that the common hepatic artery excuse me and

the first vessel heading south from there is the gastroduodenal artery that blood vessel is supplying the end of the stomach and the beginning of the small intestine and what you see is the extravagant coming off now what it's

very important if you're dealing with bleeding patients whether it's in dusky whether it's hemoptysis or GI bleeding anything like that we're looking for that type of blob appearance which just mean the contrast is no longer

constrained by the artery it's free into space okay usually the way we were built is that the blood vessels the biggest they ever are near the heart as they leave the heart they get progressively smaller until they reach

the tips of your fingers and the tips of your toes if there's any place that you see where it gets big small then big again that's not normal okay that's not normal and now we just got to figure out what's

the abnormal part is it the small part or the big part all right in this particular case it's that big blob that's big it doesn't belong there all right but in the upper GI system there's lots of collateral vessels so we can

just go in and we can put coils right in the gastroduodenal artery and we can embolize that and we can do it safely because we know that there is alternative routes for blood to flow now the one thing we have to do here and

this is an important concept for any abnormal bleeding whether it's trauma or other causes is we always look for the backdoor so in this particular patient we did an angiogram of the superior mesenteric artery there's another vessel

going to the intestines and it's nice cuz we have the coils there you can get a sense that it's possible for blood to flow from a branch of the superior mesenteric artery backwards into the GDA and so we just want to make sure that

that's not happening because we can do the best job ever with an embolization procedure but if we don't get the front door and the back door we're gonna fail patients will come back with recurrent bleeding and at least in my experience

that's a big reason why people do come back so we think we do a great job in two or three days later people come back with abnormal bleeding it's weak because we didn't address both sides of the pathology all right so here's another

patients may be asking you is like what about adenomyosis and I've been hearing something about that which is not exactly fibroids right it's a different entity though the symptoms could be kind of the same and for the years and years

and years we wouldn't have any options for patients who had adenomyosis in fact the only option for patients with adenomyosis is surgery but adenomyosis can coexist with fibroids and sometimes patient presents with adenomyosis alone

so we've had some studies now that have looked at that and although the data is not as robust and not as awesome as for patients with fibroids we do provide a performing bolas Asian for those patients with particles that are little

smaller than what we would use for fibroids with results as you're seen there before now the only other new thing that's on the market and it's not so new to you guys that are probably doing radial in femorals anyway working

in cardiac labs and IR labs it's actually what we call the trophy if you go back one slide for me mr. a the person and press play then we will be able to see that radial access I do not work for Merritt they don't give me a

dime I just thought that this was a good video is there volume on that at all if not I can just talk about it and really what it says is that if you need to a radial UFE or have radial axis for a uterine embolization patients just love

it more they and especially like patients that are already just intimidated they don't want you going near their groins at all they actually could just lay on the table we don't have to put up we don't put a Foley in

they just get a radial access the same way that you would just be starting in a line except we have special types of radial catheters and and sheaves to do that and I don't offer a radial access to

patients who are too tall for our catheters or if they've had multiple prior radial access and don't have an intact ulnar artery to complete their hand but it's much like any of that femoral access that you would normally

see they make special hydrophilic sheaths now they're called from this particular company slender technology where the inner diameter of the sheath essentially the sheath is the same like five French on the outside but they have

cored out the inside so it's a bigger diameter so it's a five six so on the outside it's a five but it will take a six French in the inner inner lumen and you know my practice we do more than 80% of all our arterial punctures with a

radial access and everybody here comes dr. Sean Deroche Nia who is the leading author of that paper for SI R and one of my esteemed partners so most patients are able to get up and walk out if you are go from a radial access the access

is actually closed with just a radial band and the complications of having a hematoma or having the patient's bleed out those just all go away but radial axis have their own complications so I'm not here to say that it is not that but

in our practice we found it to be safe and effective our patients want it and it's become like a practice differentiator so if you're working in a practice that don't do radial you EFI's right now you should mention it because

if you're in a population where the other providers are only doing femoral then you will automatically get the patients that only want that so here's a patient that had a radial access you can see a catheter that is coming from the

aorta while you can't see that it's not up and over the bifurcation but maybe you do can see that and there's a catheter in the uterine artery with the characteristic

shape of the uterine artery and the characteristic curlicue vessels of of the fibroid and on the left you can see the Imogen for beforehand and the Imogen on the right of post embolization where there is stagnant flow in the main

uterine not main uterine artery in the horizontal portion of the uterine artery for greater than five cardiac beads and again there's there's no reason that you have to know that level of detail except that you're scrubbing in but if you're

in the audience you're looking at this you're like dr. Newsome I see an air bubble there as well then I'd say good because because I do see it too so you can see the preimage and you can see the post image for pre and post embolization

these these procedures can be quick these procedures are very very rewarding and and I love to do it

today's objectives I'll start with reviewing hepatocellular carcinoma HCC

and the current treatment options I'll share the protocol inclusion and exclusion criteria and I will discuss the research treatment protocol briefly and next transitioning to research the preparation taken in the department with

staff members for trial lastly I will talk about what's involved intraoperatively from a nursing standpoint so hepatocellular carcinoma HCC is the most common primary liver manely malignancy and is a leading cause

of cancer-related deaths worldwide cirrhosis is a condition in which there is scarring to the liver causing permanent damage chronic medical conditions such as diabetes mellitus and obesity lead to chronic liver disease

obesity is a risk factor to diabetes and diabetes directly affects the liver because of the essential role the liver plays in glucose metabolism both cirrhosis and chronic liver disease remain the most important risk factor

for the development of HCC a which viral hepatitis and excessive alcohol intake are the leading risk factors of cirrhosis non-alcoholic fatty liver disease and non-alcoholic steatohepatitis which is nash our

conditions in which fat builds up in your liver thus having inflammation and liver cell damage along with fat in your liver these are other risk factors for HCC the incidence of HCC will continue to escalate as hepatitis C and obesity

become more prevalent in the United States so unfortunately the diagnosis of HCC is too often made with advanced liver disease when patients have become symptomatic and have some degree of

liver impairment at this late stage there is virtually no effective treatment that would improve survival in addition the morbidity associated with therapies unacceptably high modalities available for HCC screening include both

radiographic tests and serological markers radiological tests commonly used for surveillance include ultra sonography multi-phase CT and MRI with contrast ultrasound has historically been utilized to identify intrahepatic

lesions since the early 1980s both the photograph above shows a cirrhotic liver versus a normal liver there are visible differences in the portal and hepatic veins between the cirrhotic liver when compared to the non cirrhotic liver so

AFP alpha-fetoprotein has been used as a serum marker for the detection of HCC an AFP level of less than 10 is normal for adults an extremely high level of AFP in your blood greater than 500 could be a sign of liver tumors liver function

tests or lfts look at the part of your liver that is not affected by cancer to see how well your liver is working the lfts will be considered for diagnosis and determining the stage of HCC the tests look for levels of certain

substance in your blood such as bilirubin albumin ALP ast alt and GGT despite advances in prevention techniques screening and new technologies in both diagnosis and treatment incidence and mortality

continue to rise so treatment options for HCC can be divided into three categories surgical options non-surgical options and systemic therapy patients are screened diagnosed and treated accordingly of

these three options interventional radiologists offer the non-surgical approach which include trans arterial embolisation percutaneous ethanol injection radiofrequency ablation and microwave ablation so I want to talk

about the child pu classification the child pious core consists of five clinical measures and is used to assess the prognosis of liver disease and cirrhosis including the required strength of treatment and necessity of

liver transplant the child piu score was originally developed in 1973 to predict surgical outcomes in patients presenting with bleeding esophageal varices today it continues to provide a forecast of the increased increasing severity of

your liver disease and you're expected survival rate the Chao few score is determined by scoring five clinical measures of liver disease the five clinical measures are total bilirubin serum albumin prothrombin time ascites

and hepatic encephalopathy once scores are available in each of the five clinical measures all scores are added and the result is a child piu score their interpretation of the clinical measure is as follows so Class A would

be five to six points lease liver disease with one to five year survival weight at 95 percent Class B seven to nine points moderately severe liver disease one to five year survival rate at seventy five percent and Class C ten

to fifteen points most severe liver disease one to five year survival rate at fifty percent so which child pew scores do I our patients fall into for a research with the CPC and the majority of the HCC child pew scores a and B

seven with the survival rate of one to five years for 95% the best outcomes are achieved when patients are carefully selected for each treatment option regardless of the treatment approach

patients with HCC require a multidisciplinary approach to care to ensure optimal outcomes what we refer to as tumor board tumor board are meetings where specialists from surgery medical oncology radiation oncology

interventional radiology and others collaboratively review a patient's condition and determine the best treatment plan through this multidisciplinary approach patients have access to a diverse team of experts

instead of relying on a single opinion each specialty will have unique contributions to ensure optimal long term outcomes for patients with HCC so there are various algorithms for HCC treatment I actually have one on top of

the other there just to show you that if you're interested in the process you can look it up it's there's a few out there all right so how are the patients selected for treatment like I said tumor board and moving on now to the surgical

options there are two surgical options liver resection and liver transplant surgical resection is currently considered to be the definitive treatment for HCC and the only one that offers the prospect of cure or at least

long-term survival however most patients have unresectable disease at presentation because of poor liver function the overall resect ability rate for HCC is only 10 to 25 percent and even among those who undergo surgical

resection with curative intent there is a recurrence rate of it to 80% at five years post resection survival rates are in the range of 80 to 92% at one year sixty-one to 86 three years and 41 to 74 at five years

the most common sight of post resection recurrence is a remaining liver for patients who are not surgically resectable liver transplant is the only other potentially curative option virtually all patients who are

considered for liver transplant are unresectable because of the degree of underlying liver dysfunction rather than tumor extent down staging using local regional therapies can also be used to increase eligibility for orthotopic

liver transplant while on the transplant list patients disease progress and meeting criteria gets complicated so patients on the transplant list are and do get some other therapies

which I will later discuss so we're surgical resection is not possible for poor liver function liver transplant is a treatment of choice prior to 2008 no systemic therapy was available that demonstrated an improvement in survival

with the publication of two randomized placebo-controlled phase 3 trials the oral multi targeted tyrosine kinase inhibitor sorafenib has become the new standard of treatment for advanced HCC with an increased median survival from

seven point nine months and the placebo group to ten point seven months in the treatment group systemic therapy can be difficult to tolerate because of the side effects dose reduction or treatment interruption is often needed

despite the side-effects treatment is recommended and to be continued into a progression of the tumor is demonstrated the majority of diagnosed patients with HCC present with advanced disease oral therapy has taken two pills twice daily

equaling 400 milligrams B ID so interventional radiology it's like surgery only magic so I I always think about this when patients come in and pre-op beam and they think they're having surgery you know it's well a lot

of benefits to ir what we're doing so interventional radiology is where the magic happens and non-surgical approach procedures are performed percutaneous local ablation include ethanol injection and radiofrequency ablation microwave

ablation is utilized both percutaneously and intraoperatively and lastly there is trans arterial embolisation which depending on the embolization agent can either be chemo bland or radioisotopes percutaneous ethanol injection known as

Pei has a long track record and is very effective in destroying HCC tumors that are less than or equal to 2 centimeters in diameter performed under percutaneous ultrasound guidance a needle is placed into the tumor and absolute alcohol is

injected over recent years radiofrequency ablation referred to as RFA has largely replaced Pei at most centres RFA's also performed percutaneously advancing a specially designed electrode into the tumor and

applying radiofrequency energy to generate a zone of thermal destruction that encompasses the tumor and a 1 centimeter margarine surrounding liver RFA is thus preferable to ethanol injection for patients with solitary

tumors 2 to 4 centimeters in size for tumors smaller than 4 centimeters RFA can achieve initial complete response rates of over 90% in microwave ablation MWA microwaves are created from the needle to create small

regionals regions of heat the heat destroy the liver cancer cells RFA and microwave are effective treatment options for patients who might have difficulty with surgery or those whose tumors are less than one and a half inch

in diameter the success rate for completely eliminating small liver tumors is greater than 85% so can I get a show of hands from the audience on who what facilities are doing chemo embolization everybody pretty much are

you guys doing them next to the gentleman yeah okay so this is gonna be a boring review here alright so trans arterial embolisation a minimally invasive procedure performed to restrict to tumors blood supply it is performed

by advancing and angiography catheter into the branches of the hepatic artery supplying the tumor and injecting an agent mixed with orally contrast followed by a cluding agent known as beads the beads which range from 100 to

300 micrometers in diameter are carried by the circulation into the terminal hepatic arterioles where they lodge and include the vessel resulting in the schema tumor necrosis the procedure is done using moderate sedation patients

are monitored for 23 hours or less for pain and post embolization syndrome trans arterial chemo embolization thus is where the chemo therapeutic agent mixed with beads is injected to the tumor

these particles both blocked the blood supply and induced cytotoxicity attacking the tumor in several ways taste is the treatment of choice when the tumor is greater than four centimeters or there are multiple

lesions within the liver taste takes advantage of the fact that while the liver is refused by both the portal vein and the hepatic artery HCC survives its blood supply almost entirely hepatic artery tastes has been shown to

prolong survival in patients with intermediate stage HCC and objective responses were observed in the majority of patients tear trans arterial radioembolisation is a form of catheter directed internal radiation that

delivers small microspheres with Radio isotopes directly into the tumor y9t microspheres are administered and a procedure similar to taste the procedure has been shown to be safe and effective in cirrhotic patients with HCC the side

effects are usually well title tolerated one major advantage of y9t over taste is that it is indicated in the case of portal vein neoplastic thrombosis while taste traditionally has been considered a contraindication all right so there's

after after years in these patients so I'm gonna kind of change gears here from acute PE to chronic PE and this is actually something that I'm very interested in is actually what happens

in these patients so chronic thromboembolic pulmonary hypertension or CTF which I'm going to say for the rest of the talk because that's a lot easier is really what happens in some patients whose pee never really goes away another

term you may hear is post PE syndrome but that's the same thing essentially so post PE syndrome or CTF occurs in about 3 to 5 percent of patients with acute PE and it's a it's higher in patients with recurrent PE so if patients have some

sort of blood clotting disorder where they keep getting a clot they may get CTF we have no idea as to who is gonna be the patient who's gonna get it so we don't know right now who the patients

are and that's sort of a focus in the cardiology and IR and hematology and sort of worlds to figure out who's gonna get post PE syndrome it's one of the leading causes of pulmonary hypertension and it's really under diagnosed because

patients just don't know so patient has a PE they go through the system they go they get discharged they're alive and well and then they just never recover they're still fatigued they're just really never able to get back to their

life they think it's you know that they have this chronic bronchitis again or common or frequent pneumonia it turns out that they have post PE syndrome or CTF and it's never been diagnosed so CTF has this very complex algorithm and it

involves a lot of different teams but a patient who has PE and clinical suspicion what actually has this walk-test so they walk down a hall which is a known length and it sees how far they can get on a sir

of time and that's the six-minute walk this these patients if they have a positive six-minute walk test which requires no intervention really they go on and have a VQ scan or VQ scan with some other sort of imaging if they's

find if these tests come back with findings suggestive of CTF then they get a pulmonary angiogram in a right heart catheterization for every patient because then you have to make a decision as to what you're gonna do

surgical treatment medical treatment or now an interventional treatment so this is a VQ scan I'm a board-certified radiologist and I am NOT an expert at reading these anymore but what you what you want to look at is that if there are

areas that look abnormal that don't match so in a VQ report you're looking for areas of mismatch which means that ventilate that the that ventilation is happening but there's no perfusion so we're looking for VQ deficiencies this

has a very high sensitivity for PE but not a good specificity it's a lot less radiation exposure than CT but as we all know in a patient who has a VQ scan for a qpe we're really not sure if it's real or not but in chronic PE a VQ is a gold

standard actually at least in the initial diagnosis after that you get a

here's another patient 62 year old male

patient just a similar case who had head in that cancer again after radiation therapy who experienced some bright red blood while coughing all right here's the CT scan and what I want to draw your attention to a little tough to see I

think I'll let me go up up here point it out with a mouse well I don't have a mouse so I guess not is basically you can see right in the middle of the two lungs kind of right in front of the trachea which is the black

circle alright just go right in front of that up to the top you can see the round white circle which is the brachiocephalic artery and just projecting off the back of that is another little kind of outpouching of

contrast a little nipple coming off of of the brachiocephalic artery that doesn't belong there all right here's the angiogram and it's a little difficult to see but there is a see if I can describe it better to you alright I

think this is actually a video so I'm sorry I don't know the ability to run it unless you can click on it can you guys click on the back up so if you want to look at it again you see the angiogram kind of running and just at the origin

of the brachiocephalic artery which is the first branch of the aortic arch you can see that outpouching of contrasts coming right to the right of that vessel that's a pseudoaneurysm and again we went through the same thought process we

said you know I want to put a covered stent across that but my problem was that we didn't just have the right size that would not block one of the carotid arteries and not extend too far into the aorta so we had no choice but to

consider embolization in this particular case so here's what we did here we actually put a micro catheter if you can just click I think that's a video to the left no I guess not you know what it's okay

what we did for this particular case was we went in from the arm and we put a micro catheter directly into that pseudoaneurysm because we couldn't feel we didn't feel we could put a stent across it so we put the micro catheter

in there we started to put some coils and it actually went further than we thought outside of the artery and here's the post image so you can see our final image you can see the coils that are sitting just adjacent to the

brachiocephalic artery and we preserved good flow there to end this basically

case I can make up the ages anyway so it doesn't matter so 43 year old patient on a motorcycle that collided with a deer all right presents with left upper quadrant abdominal pain and now we're looking at a cat scan all right who

wants to look at a cat scan you look like you're up for it what do you think what do you see no no you're not sure so we're looking so the key is the left upper quadrant pain right the patient presented with left-sided pain you

should know that whenever we're looking at a study like this we're looking as if we're talking to the person so the right side is on the left the image the left is on the right side and so if you look on the these are two

images if you look at the right side of the image you can actually see the spleen that's like that beam shape thing towards the back of the patient and what we should see is a homogeneous appearance of the organ but what we're

seeing are some kind of dark grayish lines going through it that's essentially a laceration of the screen that's what we're looking at that's the pathology that will prompt us doing a procedure like this and when we ever we

see a patient with splenic trauma we try and grade the trauma so one thing you're going to hear about is it's a patient with a grey 2 laceration or a great 4 laceration or something like that and that basically just describes the extent

of the laceration through the spleen the further through the spleen it goes the higher the number is the worse it is for the patient okay we tend to get involved with patients who who essentially have grade 3 or higher lacerations and are

hemodynamically stable so in this particular patient this was thought to be a grade 3 splenic laceration but there was not a whole lot of blood around the spleen so we thought this patient had some time to come to

angiography and embolization so here's the angiogram lo and behold what we see is again a blobby thing which is the theme of this lecture remember this is bleeding so we're looking for blobby things and all the way on the right side

of that image you can see that cloud of contrasts that black contrast that's extravasated of contrast that's not normal all the way to the right you guys see it are you good so going all the way to the right that's

what we're trying to do now when we do splenic embolization there's two ways we think about this do we want to go all the way to where the bleeding is all the way out into the screen and embolize one little branch that's injured or do we

want to do something called the proximal splenic embolization we would just put like some coils or plugs right at the origin of the splenic artery with the goal of being to slow down the flow and allow the spleen to heal a lot of it is

just what's possible maybe what time it is how tired we are things like that all factors that weigh into it but here's a little bit of a better view you can see the area of extravasation now here's another picture now we put

our microcatheter out there now you're getting a bit more of a sense of what's going on there you can see the extravagance II the vessel that it's coming from and then we put our catheter all the way out there and now we're

right at the source of the bleeding so our philosophy is if we see bleeding we want to go as far as we can towards the source of the bleeding keeping in mind that whenever we don't get as close to the bleeding as possible we're

sacrificing normal parts of the organ that we're treating and that's the philosophical leap that we make during these procedures so we were able to get out there and then we embolize leaving a lot of flow through the rest of the

spleen and the patient was able to survive like we never did anything alright that's our goal now here's a

patient 40s year-old patient again car accident lower abdominal pain and bruising so it sounds like you guys can appreciate that's an injury alright so we'll move past that so here's a CT scan these are four separate images from the

same patient CT scan and it is a bit more subtle I'm not suggesting it's easy to see you know we can appreciate the injury but one thing that you should be able to notice again is that concept of symmetry so when our residence or even

myself or anybody reads a cat scan we always want to kind of appreciate all the differences in the symmetry that we're seeing and so what you can see here is especially on that upper left hand side you can see the penis coming

out of the patient almost coming out of the patient and if you just draw a line straight back from there you should notice that there's a bit more tissue on the left side of the patient than the right side of the patient but that's

what we're looking at and if you go to the image over to the right the top right image right at that same area there's a little bit of a white blush which just shows that there is some bleeding going on there and if you look

at the third image which is the one on the bottom left right below one of the bones or there's another area of a white contrast collection or bleeding all right you can maybe see that again on the fourth image so that's what we're

looking for on the CT that asymmetry or the thickening of the tissue and we're looking for an escape of some contrast from where we should expect it to be all right so many of these patients will be

unstable those are the patients that probably need to go right to the or but for the patients who are really you know doing okay we have a chance to intervene on them and the reason why that's important is the more unstable they are

the higher the chance of mortality especially with the pelvic fracture so pelvic fractures are a big deal if you have a hemodynamically unstable patient with a pelvic fracture that's something to take very seriously

all right many of these patients will get CTS or C if we see extravasation they often come to us for angiography so here's the angiogram again a great example if you only look at one picture or two pictures

you're not going to see the problem all right so if you look at the first two pictures you really don't see anything I would I would argue it looks normal but as you get to that third picture you see that kind of collection of contrast

on the bottom right-hand side of the picture all right that's why you need to look at all the pictures of the and reom not just one picture you watch them it's like watching a

little movie now you just stand there and watch it over and over again I get a sense of what it looks like at the beginning middle and end of the angiographic run or set of images the other thing is it's very hard to see

extravasation of contrast when you're in the aorta so many times we do an aorta gram we take some pictures and we may or may not see anything but if we know there's a pelvic fraction we know it's more on the left side we'll go into the

left internal iliac artery and do a more selective angiogram and here's a picture of that selective angiogram and now you can see the extrapolation even more clearly hopefully you can all see it the bottom kind of leftish part of the image

all right here's a more selective now we say okay we definitely see something now we're going to get a little bit further into the system here's a picture now it's very clear you can go if you don't see it all right so you should see it on

the bottom all right and now our goal is to just get as close as we can and so we got all the way down then we put some coils there and again our goal is to make sure that we get just into the vessel that we treat and embolize it now

people will say what agent should we use do we use gel foam do we use particles do we use coils do we use glue or onyx the truth is you can you can really use anything but the thing with the most control so for trauma we tend to use

coils for trauma alright because our goal is to deposit an embolic agent right at the site of the injury that's our goal if we use particles we don't have as much control or a liquid we don't have

as much control they could go somewhere we don't want it to go all right here you're dealing with the blood supply of the penis the rectum the bladder other things which you know most of us would prefer not be injured during an

angiogram all right so we don't want to do something that we don't have complete control over and coils give us that type of control

talk here with something that's new on the horizon believe it or not it was actually on the horizon 20 years ago and then it went away because there were a lot of patients that were treated with a

lot of complications and it's making a resurgence and this is balloon pulmonary angioplasty or BPA for short so this is an intervention which may be feasible in non-operative candidates so I mentioned to the Jamison classification earlier

type 1 and type 2 disease should be treated with surgery again it should be treated is curative but patients with type 2 and a half or 3 disease can be treated with balloon pulmonary angioplasty in the right in the right

frame which means that a surgeon has said I cannot operate on this a medical doctor has said boy they're not going to get better with their medicine let's try something else well this is that something else and that's what involves

everyone in this room so this is these are usually staged interventions with potentially high radiation and contrast dose if you think about it it's like Venis recan and a pulmonary AVM all-in-one so it's a potentially a long

complex procedure with a lot of contrast and a lot of radiation but it can provide a lot of benefit to these patients I'm going to talk about the comp potential complications at the end which is one reason why not

everyone should do these all the time so this is a pulmonary angiogram from the literature when you're injecting a selective pulmonary artery you can see that this patient has multiple stenosis there's no real good flow there the

vessels look shriveled up like I mentioned to you before you can get a balloon across it and balloon the areas and then you can see afterwards so the image a on the left is before an image D is afterwards believe it or not this are

in the most experienced hands because the most experienced hands are for palm the BP AR in Japan they do hundreds of cases of these a year at each hospital I've personally only done five so but this is a something that I'm very

interested in and you can see how how much benefit it has for that patient another way you can see these are the webs and the bands that I mentioned to you earlier so what's interesting is that if you look on the first set of

images on the top and the images on the bottom those are the same patients it's the same view before top rows before and the bottom rows after balloon pulmonary angioplasty so the first image is a pulmonary angiogram where if you kind of

see this there's there's some area areas of haziness those are the webs and bands the image on the the middle is the blown-up views and you can see those areas and then the image on the right is intravascular ultrasound which I use

every day in my practice it's a catheter with an ultrasound on it and when you look at it on the top image image see you can see a lot of thrombus you're actually not seeing flow and on image F on the bottom you're seeing red which is

the blood flow so these patients can actually improve the luminal diameter bye-bye ballooning them you can treat occlusions again image on the left shows you a pulmonary artery with a basically an occlusion proximally and then after

you reek analyze it and balloon it you can see that they can get much more

so let me just be honest you know two things about me when I speak I can't stand still if you've ever heard me talk

before so he always has to make me up but secondly I don't think I'm gonna make it through this without getting emotional I feel like if I can get through this whole spill without it being an ugly cry then I look like it's

a success and if you don't know what that is you can Google Kim Kardashian ugly cry so all right so I had the opportunity to go to Tanzania in October November of this year and be part of the first ground zero nurses on the ground

and the first IR there and let me tell you how this went down the end McNamara was really involved with rad aid before she got off our board and one day I had a wild hair and told Bruce from our management company was like hey I think

I want to do one of those trips can you hook me up with Patti over at Rite Aid and he was like yeah sure so Patti calls and she said you know I think he'd be great for a tanzania project I'm like great let's go and she's like wait now

who are you and how do we how are you even affiliated with Arab and I said no where's Tanzania so that's where it's at and if you know me I'm kinda like eh let's go and I don't even know where we're going and it's a 23 hour flight in

case you're interested but Tanzania is a country of 60 million people for you to get a perspective of what that looks like it's California and New York State's population combined and could you imagine not having an IR we've

have five IR s in Little Rock Arkansas going down one small interstate that looks like no biopsy no drain no just the very basic IR procedures that we take for granted don't exist there or didn't before we got there so in October

of 2017 the Yale read a chapter went down there and they assessed the potential for establishing an ir intends and so based on these findings they decided with went collaboration between the movie and Billy National Hospital

the orthopaedic Institute which you're actually like toothed small hospitals on the same campus or actually excuse me MNH is very large and then mo I is kind of smaller but on the same campus there University and the Rite Aid chapter they

would joint plan to start the first ir so the program consists of three components which is practical training a curriculum development and then finding a way to create some sustainable product development you're probably probably

aware you hear about people donating products to these countries but there's the sustainable how do I create a program in a process where we're not just waiting on someone to donate something where we can keep this our

system going so the program overview so this was we're going on two-week rotations over three years and the teams consist of an IR doc and RN and Artie we were the first group to go over in 2018 and so our goals are in year one to do

basic percutaneous procedures biopsies and drains year to going to vascular access and in year three doing more angio type cases like tase's embolization zan etc and developing a teaching curriculum because while there

is a radiology program for residents there was an IR specific one and they're creating that now so our goal is the first nurses on the ground was to provide this comprehensive nursing assessment to help map the project over

the next three or five years now when they went in the year before you can imagine all of the infrastructure assessment all of the you know the equipment there was so much that went into that but the nursing piece was our

job as the first people on the ground and this was so incredibly well received in Tanzania and they were so excited that we were on the front page of the Guardian you can see our doctors Eric and aza down at the bottom right who are

actually here at SAR this week on what looks like to be Good Morning America in Tanzania and when I arrived I was I found out we were having a first conference and there was a camera in my face so I'm

not sure what's which Swahili speaking news outlet I was on but I think I might have been on one and to the left you can see David Pro logo was the attending that I worked with at the same press conference so what I'm trying to say is

no pressure I was like we got it no pressure we have to create this nursing assessment and we wanted to do a good job because it was very well received in the media and we wanted to make sure this all went off really well I would

my last case here you have a 54 year old patient recent case who had head and neck cancer who presents with severe bleeding from a tracheostomy alright for some bizarre reason we had two of these

in like a week all right kind of crazy so here's the CT scan you can see the asymmetry of the soft tissue this is a patient who had had a neck cancer was irradiated and hopefully what you can notice on the

right side of the screen is the the large white circles of contrast which really don't belong there they were considered to be pseudo aneurysms arising from the carotid artery all right that's evidence of a bleed he was

bleeding out of his tracheostomy site so here's a CTA I think the better image is the image on the right side of the screen the sagittal image and you can see the carotid artery coming up from the bottom and you can see that round

circle coming off of the carotid artery you guys see that so here's the angiogram all that stuff that is to the right to the you know kind of posterior to the right of the screen there it doesn't belong there that's just

contrast that's exiting the carotid artery this is a carotid blowout we'll call it okay just that word sounds bad all right so that's bad so another question right what do you want to do here

I think embolization is reasonable but probably not the thing we can do the fastest to present a patient to treat a patient is bleeding out of the tracheostomy site so in this particular case this is a great covered stent case

alright and here's what it looked like after so we can go right up and just literally a cover sent right across the origin of that pseudoaneurysm and address the patient's bleeding alright

so who are the most ideal candidates for fibroid embolization obviously I would say the most ideal candidates are patients that are symptomatic and I've told you already that 80% of black women

have fibroids but guess what only half of those will be so symptomatic that they would need to be even treated so just because fibroids exist don't mean that they need to actually be treated already so you

to actually have symptoms most patients that are symptomatic will again wait to getting treatment for like three and a half to five years but when they come we want to make sure that they're symptomatic and that they're not trying

to become pregnant and I know somebody in the audience has a question around that already so let's hold your high horses I'm coming to that how about patients that don't want to have surgery or just don't have time to

have surgery they don't have time for long recovery if you don't care if you have your uterus or not then I'm not so sure that you need to be pursuing a uterine sparing procedure okay and I'm gonna pause here to address one other

thing that it's a myth it is a myth that if you do not need to have children then you do not need your uterus I beg to differ and when we talk to women they are quite upset about this preposition that the uterus is only there for

baby-making purposes in fact there have been several studies now that have come out to say that women that have had early hysterectomy even with their ovaries in place are predisposed to coronary artery disease or

cardiovascular events we would like patients that are poor surgical candidates because if they can have surgery then they may be able to have surgery or patients that do not desire future fertility patients that have

already concerns about hysterectomy because of religious reasons or don't want to have hormonal therapy and I actually like patients that have have a have obesity because if we are able to do this procedure then they're spared

more complications related to surgery so the ideal patient then and this is a very important point said all three criteria would need to be fit that if you're a patient in order to be offered embolization number one

you have to have fibroids believe it or not you have to have symptoms that are related to fibroids and then you have to have some MRI that says that the location of where your fiber it is is causing that symptom and that these

fibroids are vascular let me explain okay and I'm going to skip this so I've been working with people for a long enough time and I've work of Julie for years I've worked with Diane and Anna and some other people for like ten years

and imagine if you're working with me for ten years you know that you're probably going to be able to do this procedure too like you're scrubbing right next to me eventually like you pick these things up what I get paid for

is not to do that and for the experienced nurses and techs that are in the room you know exactly what I'm talking about you're better than the doctors half of the time you really could do this procedure but what I get

paid for is to decide who does not even get to come on the table to get this procedure done so pay attention to this slide and these this criteria is being challenged every day and we're getting more and more data to say that this is

old information that we used to say if the uterus was like more than six months then you probably shouldn't have a uterine sparing procedure but we know that we do in embolization all the time in patients that have large fibroids

anyway but there's no data to actually give us that information most of the trials that we have and we have had a lot of them they have excluded patients where their individual fibroids were greater than 12 centimeters if you have

had an indeterminate and de metrio biopsy or you're having abnormal pap smear doing a uterine sparing procedure makes no sense so we use these imaging to really help us to determine which patients really

deserve to be treated so everybody can see that that image on the Left where it says submucosal refers to and I'm gonna try and come down so I can see these images here and you can see that there is a fibroid that is in

truck hava teri do you see that that round thing that is surrounded by the white fluid that is someone that has what we would call a type zero fibroid completely within the unit of course this is going to cause bleeding but

should this person have a uterine artery embolization or a hysterectomy Gail no this patient should have like hysteroscopic resection like a D&C and they would just scrape that thing out and then their symptoms would go away or

the patient on the right that has a normal appearing uterus and then this pedunculated gigantic thing that has bled into itself that is like a sub serosa fibroid of the extreme just hanging off on the outside now should

this patient have embolization no someone can tie a string right at that little connection and take that thing out so using our imaging to help us to decide which patients should be treated is very important or this patient who

came with Oh dr. Newsome I've been bleeding for 10 weeks in a row I have reversed cycles I have bulk I have bladder symptoms and yet they have that little dot that little black thing there that little dot

at the top that is the only place where there's a fibroid so this patient should not be a candidate for embolization either because yes they have symptoms and they have that little tiny daughter for fibra but that is not what's causing

those symptoms so it is important that we're not doing procedures on patients just because we can but because we're using our imaging and the patient's symptom to decide which patients are the best candidates for these procedures

Sean I know you have not seen these slides at all you wanted I John can talk about this with his eyes closed so it's

not like there's anything but this is the data that was published from the Jade publishing jvi are from what Sean has written and it's just the current standards relating to what you should be expecting what we tell our patients that

they should expect for outcomes as it relates to uterine artery embolization again I'm not really here to try to point this I know you can google these you can get the information yourself but just to say that all of our procedures

have risk and we need to be clear with our patients about them now I believe that with all of these risks combined the benefits of doing uterine fibroid embolization for most patients is far greater than the risk and that's why I

really do have my practice so these are the benefits right shorter hospital stay and I would say more cost-effective and that is really debatable because gynecologists have become smarter and smarter now they're doing like same-day

hysterectomies if you have a vaginal hysterectomy then maybe a UFE is not as cost-effective because they don't have to do an MRI beforehand and they don't get an MRI afterwards and do all of that anyway and if you look at the long-term

cost of that then maybe having a hysterectomy in some patients could be that but we know for sure that patients are more satisfied when they get a embolization procedure than in my MEC to me not in the beginning run because the

procedure can be very painful that is not the procedure itself is painful but post embolization syndrome which could last anywhere from five to seven days can can be very painful again this is the comparative data that was published

by dr. Spees who is our gold medal winner this year understand a lot a lot of work in this space has allowed us to have this conversation with our gynecology partners but also with our patients as we talked about like when

can you return to work how long are you going to be all for you know am I going to need extra child care or whatever how long would I be in the hospital this information helps us to inform our patients about that then on average

you'll stay in the hospital around you know a day or so and most uterine artery embolization procedures are same-day procedures and interventional radiologists are doing these in freestanding centers as well as other

providers without any issues so we're almost down to the end we know that fibroid embolization is proven to be an effective and durable a procedure for controlling patient symptoms it's minimally invasive and it's outpatient

most patients can go back to some normal activity in one to two weeks it has a low complication rates and some patients mein neatest to surgery and should have surgery so in our practice we send around 1/3 of our patients or so to

surgery and the reason that that is that high is that patients are allowed to come and see myself or dr. de riz Nia from the street they do not have to be referred from their gynecologist and so they're just coming from the street then

you will be referring them to a gynecologist because of some of the things that may not make them a good candidate for embolization such as this

patient who experienced the heart attack who had right little quadrant pain after a cardiac catheterization all you like oh so here's the cat scan and what you should appreciate there is in the front of that first image which is the axial

image all right you can see the hematoma that's brewing kind of in the front you notice how all these pictures kind of look the same that's the good part about giving a lecture on bleeding and trauma because they all kind of look the same

so that's the hematoma on the front part of the pelvis and on the on the right image which is more of a coronal like looking at the patient image you can see it right near the right groin you can see that hematoma all right so our next

step was to do an angiogram and this is what the angiogram looks like who wants to volunteer what do they say all right I saw someone raise his hand over here some walk over here what do you think yeah well yes so it is a retro hematoma

would you say describe the angiogram for everybody right where it's at the external iliac down the common femoral looks like there's contrast going up to the left and down to the right probably close to where they accessed yeah

probably but so yeah probably probably too high but the other thing is that's probably a pseudoaneurysm that probably is the evidence that there was a bleed there we're not seeing Frank extrapolation of contrast in a literally

contrast pouring out but we are seeing the effects of an injury to the artery and the constraining of the the remaining normal tissue to hold on to that bleed so the question is what do we want to do no that was very good because

I fooled you it's not always embolization so sorry I lied so in today's world a lot of times when we see this type of pathology we have again relatively new technology available to us again we

could go into that pseudoaneurysm and embolize it and that would be a legitimate treatment but my friend here is right you know this is a great case for a covered stent so we could go in and put a stent right across that area

of injury and stent it so these days looking at coverage stands as an option for patients with arterial injury is a very legitimate option you just have to be able to deliver it has to be the right artery you have to be able to get

the stent where it needs to go we all work with vascular surgeons who are great and they can put these stents and iliacs and aortas but they can't make those turns into livers and kidneys and spleens it's got to be the right artery

this is this is the right artery okay we saw this patient and we said well we could kind of get a micro catheter into that area of injury and embolize it or we could just put a cover sent across it and all go home to have dinner with our

kids so that was option B is what we chose here so this is a great cover stent case okay here's another patient

24 year old patient after a car accident has lower abdominal pain and melena so blood coming out of the rectum here's the CT scan anyone want to take a stab but you can just shout it out

so this time we're looking at the liver right so the liver is the big thing on the right side of the screen and what you can see is the dark hematoma posterior to the liver but you should also notice that big white dots sitting

right in the hematoma all right that's important because that's active bleeding that's the report when you guys when you guys get called in for these cases and someone says oh this you know liver trauma with active

bleeding this is the picture that is spurring that announcement okay this is what active bleeding and the liver looks like again there's a bleeding scale there's an injury scale for a liver trauma we don't need to go into that

slides are available if you want them alright here is the angiogram now again my rule works all right if you see vessels get smaller and then big again something's abnormal so in this particular picture I want you to notice

the catheter sitting in the right hepatic artery the blood is going up into the right lobe of the liver and right near the top of the pictures that big circular kind of blobby thing now this is by definition extravasation

sometimes we use the term pseudoaneurysm to describe this I just want you to appreciate what a pseudoaneurysm means it means that there's a hole in the artery that contrasts or blood is leaking out of that hole and the body is

essentially constraining the bleeding it's not going all over the place it's being constrained that's what we call a pseudoaneurysm all right that's just one way to look at it and geographically so this is an injury to the artery blood is

leaking out of the artery but maybe one layer of a three-layered blood vessel or even just the surrounding tissue is constraining that bleeding alright so what do we want to do for this exactly exactly you're getting it all right so

here we can get our microcatheter all the way out there the closer we get to it the better now in end organs like the liver or the kidney we don't actually have to get all the way out there getting close to it's going to be good

enough but the closer we get to it the better for stopping the bleeding and preserving the function of that organ all right so look how close we literally got right into the injury and then we're able to embolize it that's the goal all

right now the liver is a nice place the treat because as you know there's two sets of blood vessels going to the liver there's the portal veins in the apat ik artery so if we just embolize a little a patek artery the

liver is not going to notice that at all because it still has the portal venous flow bringing blood to that liver but our goal is to get in there preserve as much of the liver that we can and address that injury okay here's another

60s year old patient with afib who fell and presented with abdominal pain and bruising in their anterior abdominal

wall for whatever reason we see a lot of these patients who come in with kind of bruising after they fall on their abdomen here you can see why hopefully you can see the big hematoma and the anterior abdominal wall so you can

imagine what this patient look like they have this kind of you know ball sized thing under their abdominal wall all right here's our angiogram in this particular case we went into the inferior epigastric artery which kind of

runs up from the pelvis up along the anterior abdominal wall you can see how small it is we were able to get a micro catheter in there and just in the middle just to the left of the middle of the picture you can see that kind of black

your circle that's again a pseudoaneurysm arising from the branch of the inferior epigastric artery and boom we can go in and coil it all right so that's what that looks like so now all of you kind of maybe I used to

sitting in the background we'll know when you're getting called in for these patients this is the type of pathology that we're looking at on CT and on angiography all right another patient 68 year old

questions comments and accusations please hello this topic is very personal to me I've had it actually had a UFE so this is like one of my big things I work in the outpatient center as well as a

hospital where we perform you Effy's and frequently the radiologist will have me go in and talk to the patient it's from a personal perspective one of the issues which it may just have been from my situation was pain control post UFE

whether you normally tell your patients about pain control after the UFE someone say we are all struggling with this yeah oh it's not what's your question is going to be okay good I'm gonna get doctor Dora to answer Shawn the question

is what do you what do we do with this pain issue you know what are you doing for the home there at Emory there you know and a lot of practices we we don't rely on one magic bullet for pain control recently we've been doing

alternate procedures for two adjunctive procedures to help with pain control for example there are nerve blocks that you can do like a superior hypogastric nerve block there's there's Tylenol that can be given intravenously which is seems to

be a little more effective than by mouth there's there's a you know it and a lot of times it's it's a delicate balance right between pain post procedural pain because you can often get the pain well controlled with with narcotics opioid

with a pain pump but the problem is 12 hours later the patients is extremely nauseous and that's what keeps her in the hospital so it's a it's a balance between pain control and nausea you can you can hit the nausea

beforehand using a pain and scopolamine patch that that'll get built up in the system during the procedure and that kind of obviates the nausea issues like I said that the the nerve blocks the the tile and also there are some other

medicines that can can be used adjunctive leaf or for pain control in addition to to the to the opioids so the answer the question is there are multiple there multiple answers to the question there's not one magic bullet so

that helped it did one of the things that I tell the patients is that you know everyone is different and yet some people I've seen patients come out and they have no pain they're like perfect and then some come out and they are

writhing in the bed and they're hurting and they're rolling all around what and I always ask the acid docs are you telling them they could possibly have you know pain after the procedure because some have the expectation that

I'm going to be pain-free and that's not always the case so they have an unrealistic expectation that I'm gonna have the UFE but not have pain what I also tell them is that the pain it's kind of like an investment right and

this is easy for a guy to say that right but but it's it's an investment the worst part the worst pain you should be feeling is the first 12 12 hours or so every day I tell my patient you're gonna be getting better and better and better

with far as the pain as long as you is you follow our little cookbook of medicines that we give you on the way home and I want you to make sure that you fill these prescriptions on the way home or you have someone fill those

prescriptions for you before he or she picked you up in the hospital and lately we have been and I see that you're there as well lots of other little tricks that are out there right and again there are all

little tricks so ensure arterial lidocaine doctor there is near alluded to and if you're on si R Connect you may it may spill over on some of your chat rooms here people have been using like muscle relaxant like flexural or

robertson with some success but just know that we don't have any studies that tell us how that's supposed to do so when i have someone that is like writhing in pain i just use everything so i do it superior hypogastric nerve

vlog and i actually will do some intra-arterial lidocaine although not so much lately i have been using the muscle relaxant but i will warn you that i've had two patients with extreme anticholinergic effects where they are

now not able to pee from that so you know where we're doing that balance act I see that you're there can I take that question here first just so we're we're doing the same thing we're using the multimodal just throwing all these

things at people and we're trying the superior hypogastric blocks but we're collaborating with anesthesia to do that right now do you all do your own blocks or do you collaborate with anesthesia we do our own blocks okay it isn't it is

not that difficult I would tell you that but again it's kind of like you know you got to do if you start feeling better and then you're like we don't really need them we'll just do it on our own okay thank you again yes what's the

acceptable interval between UFE and for IBF oh that's a your question what is the interval between UFE and IVF so if you wanted to get pregnant yeah and can you have a you Fe and then have an IVF like how long would you have to wait

wait and tell you before you can have that the IBF it I guess it really depends on the age of the patient because we know that that the threshold for which patient tend to have that inability to conceive

is around 45 years old so you know it did below the you know below the age of 45 the risk of causing ovarian failure or or the inability to conceive is significantly less it's zero zero to three percent so I would say that you

know you probably want the effects of the fibroid embolization to two to take effect it takes around 12 months for these fibroids to shrink down to their most weight that they're gonna they're going to shrink down the most I wouldn't

say you need to wait 12 months to put our nine vitro fertilization there's no good there's no good literature out there I don't believe that's your next and so I would say just remember that if you came to my practice and you said you

wanted to get pregnant I will be sending you to talk to fertility specialists beforehand we do not perform embolization procedures as a way to become pregnant there's no data to support that but if you saw your

gynecologist and they said let's do this then I'm sure they'll be doing lots of adjunct things to figure out what would be an ideal time then to for you to have IVF and if I dove not having any data to inform me I would ask you to wait a year

and what will be the effect of those hormones that they gave you if for example a patient has existing fibroids what would be the effect of those hormones that IVF doctors prescribed their patients yeah so fibroids actually

can grow during pregnancy so I would say that most of those hormones are pro fertility hormones so I would expect that maybe you can see some of that effect as well yeah alright if you have any other questions you can grab me oh

you're I'm sorry go with it okay yes we we have time I don't want to keep anybody here for that so I have a two-fold question the first one is post-procedure can you use a diclofenac patch or a 12-hour pain

patch that is a an NSAID have you have any experience with that and your next question my second part of the question is there a patient profile or a psychological profile that tips you that the patient is not going to be able to

candidate because of their issues around pain so they're two separate but we have in success sending people home that first day so I'm looking to just make it better I haven't had experience with the Clos

phonetic patch it's in theory it seems ok you know these are all the these are they're all these are non-steroidal anti-inflammatory drugs so there are different potency levels for all of them they you know they range from very low

with with naproxen to to a little bit higher with toradol like that clover neck I think is somewhere in between so we found that at least I found that that q6 our our tour at all it tends to help a lot so with that said I I don't have

much experience with it with the patch in answer to your second question the only thing I can say is there there is a strong correlation between size of fibroids and the the amount of a post procedural pain and post embolization

syndrome so there really you know we often say we don't really care too much about the number of fibroids but the size of the fibroid is is is should be you know you should you should look at that on pre procedural imaging because

if it gets too big it may not be worth it for the patient because they may be in severe pain the more embolic you put into the blood supply's applying the the fibroid the the greater the pain post procedural pain

are there multiple other factors that would contribute to pain but that's that's one aspect you can you can look at post procedurally on imaging okay thank you very much yes ma'am hi what what kind of catheter do you use

to catheterize the fibroid artery when you pass by radio access yeah so over the last three years the companies have been really very good about that so there are a few things that I without endorsing one company or the other that

you need to make sure that the sheath that you're using is one of those radial sheets a company that makes a radio sheath you should not use a femoral sheath for radial access so no cheating where that's concern you may get away

with it once or twice but it will catch up to you and you need a catheter that is long enough to go from the radio to the to the groin so I'm looking for like a 120 or 125 centimeter kind of angled catheter whether it's hydrophilic the

whole way or just a hydrophilic tip or not at all you can you can choose which one in our practice most of us still tend to use a micro catheter through that catheter although if I'm using a for French and good glide calf and it

just flips into like a nice big juicy uterine artery then I may just go ahead and take that and do the embolization if the fellow is not scrubbed in as well so thanks a lot but they make they make many different kinds like that and more

of those are to come all right I'm you can please please please send us any other questions that you have thanks for your time and attention and enjoy the rest of the living
