injective microphone or vairocina another Don Thurman onto messin this has

lower occlusion rates but remember we're not focused on lower occlusion rates will focus on how did it affect the patient and we already heard this is where the vcm q came from ok this was in conjunction with the FDA

they develop this the company that makes a very thin it is available now it's it's the first form that's approved by the by the FDA member homemade foam theoretically is not approved by the FDA it's approved for in company great

sadness answer accessory saphenous varicosities for above and below the knee the company specifically did not go for getting it to be indicated for the small saphenous doesn't mean you can't do it but they did not that was a

decision because they were concerned they might get more TV tease in their in their studies and and so it's basically it's not proven small saphenous but you can do with it what you want of off-label i guess and they were looking

at improvement of symptoms of the superficial and competence and the appearance of visible varicosities and

who came in with just over she had a four month with delayed heal wound she finally presented at us after the wound

healed because she had rest pain that wasn't recognized they thought the pain was due to the the wound the wound healed and they realized oh she still has pain well that's because she has crippled limb ischemia and so she was

she was brought in for that just you know she has bilateral disease I'm just gonna concentrate on talking about the right leg for for today's discussion but she does have inflow disease in these types of patients I do get

cross-sectional imaging so I can determine just how extensive the iliac diseases or if it involves the aorta to then determine what it what to make sort of jumping into it so the right leg again she has about a 10-7

occlusion of the bright SFA this occlusion here's the femur for reference the knee is actually down way down here so this is actually just above the a doctor again tried to use in this case I did do wire work I got past a good

portion of it here's my wire right here and here's the O pacified lumen so what you can see is the wires actually adjacent to the lumen so at this point I'm re said suspecting that I'm sub intimal I confirm that by removing the

wire do little puff there's blushing that blush is up intimal so I know I'm sub intimal so at this point what were the things you can do obviously the first things you do try to pull that back try to find a different space a

different location to wreak analyze when that's not successful then you start thinking about southern super recanalization multiple devices for that there's the outback device which is a little hook that you can try to spear

yourself into the main lumen and pass a wire there's also device from Medtronic about the anterior device what this is it's a balloon that you inflate to sort of stick yourself into that wall it has two ports that are on the side one

points one direction one points the other direction it allows you to find that open lumen and we use a re-entry angled wire to get back in so in this case just as a cartoon here's the the anterior device place downward this is

would be the balloon inflated you would basically jab into the port into the into the main lumen so that's sort of basically what I did here again here's the agile device each of the ports you can see as a little divot once you put

it sideways you can determine which we are going to stick there's my wire right into the lumen and there it is down further into the rest of the the vessel subsequent to that pre-dive it with a three and then overlapping

since were used finally here is her post i did treat both legs but you can see just the dramatic difference going from the monophasic waveforms to tri-phasic waveforms restoration table api's for her I couldn't help but throw this in

treatment options once you've sort of isolated that there are leaky valves and the patient has typical symptoms that there are some surgical options but really embolization and catheter

directed treatment are really the mainstays of treatment both because it's an outpatient procedure you get to go home the same day and the recoveries fairly easy the factors that we consider when you embolize or block these

varicose veins are listed here you want to you want desired duration you want it to be closed forever you can't replace valves it would be nice to be able to do that but there's not a valve replacement so much like in the leg when you're

treating varicose veins you're either blocking or taking veins out so the surgical options are to take the vein out or to ligate but and the vascular options would be to block it and so I would just thought I would cover just a

little bit of embolization materials I'm sure you're all very familiar with and as I'll mention a little bit later there's there's sort of not necessarily agreement on what type of things people use to embolize gonadal veins or pelvic

varicosities but i'll show you what i do but give you a background of just generalized embolization materials so I'm sure you've all seen gel foam supplied as a sheet you can make a slurry you soak it with contraire

so that you can see it as you're putting it in some people use glue and will glue the entire gonadal vein it solidifies when it's mixed with saline or blood usually mix it with acai it also you can see it as

you're injecting it and then the standard coils which there are multiple sizes shapes detachable non-detachable Amplatz or plugs all the mechanical devices that can be used to block blood vessels and then I put on Souter deck

all because there are some people that will sort of do the sandwich technique you may have heard we'd put a coil peripherally and a coil up by the renal vein and then in between the coils you can film a sclerosant and embolize that

way the other important factor for me is using the suture deck all on the actual varicosities I'm not just necessarily treating or blocking off the the blood supply to them you know and I'll mention that a little bit more during the case

here so go through a case patient with

so just a compliment what we everybody's talked about I think a great introduction for diagnosing PID the imaging techniques to evaluate it some of the Loney I want to talk about some of the above knee interventions no disclosures when it sort of jumped into

a little bit there's a 58 year old male who has a focal non-healing where the right heel now interestingly we when he was referred to me he was referred to for me for a woman that they kept emphasizing at the anterior end going

down the medial aspect of the heel so when I literally looked at that that was really a venous stasis wound so he has a mixed wound and everybody was jumping on that wound but his hour till wound was this this right heel rudra category-five

his risk factors again we talked about diabetes being a large one that in tandem with smoking I think are the biggest risk factors that I see most patient patients with wounds having just as we talked about earlier we I started

with a non-invasive you can see on the left side this is the abnormal side the I'm sorry the right leg is the abnormal the left leg is the normal side so you can see the triphasic waveforms the multiphasic waveforms on the left the

monophasic waveforms immediately at the right I don't typically do a lot of cross-sectional imaging I think a lot of information can be obtained just from the non-invasive just from this the first thing going through my head is he

has some sort of inflow disease with it that's iliac or common I'll typically follow within our child duplex to really localize the disease and carry out my treatment I think a quick comment on a little bit of clinicals so these

waveforms will correlate with your your Honourable pencil Doppler so one thing I always emphasize with our staff is when they do do those audible physical exams don't tell me whether there's simply a Doppler waveform or a Doppler pulse I

don't really care if there's not that means their leg would fall off what I care about is if monophasic was at least multiphasic that actually tells me a lot it tells me a lot afterwards if we gain back that multiphase the city but again

looking at this a couple of things I can tell he has disease high on the right says points we can either go PITA we can go antegrade with no contralateral in this case I'll be since he has hide he's used to the right go contralateral to

the left comment come on over so here's the angio I know NGOs are difficult Aaron when there's no background so just for reference I provided some of the anatomy so this is the right you know groin area

right femur so the right common from artery and SFA you have a downward down to the knee so here's the pop so if we look at this he has Multi multi multiple areas of disease I would say that patients that have above knee disease

that have wounds either have to level disease meaning you have iliac and fem-pop or they at least have to have to heal disease typically one level disease will really be clot against again another emphasis a lot of these patients

since they're not very mobile they're not very ambulatory this these patients often come with first a wound or rest pain so is this is a patient was that example anyway so what we see again is the multifocal occlusions asta knows

he's common femoral origin a common femoral artery sfa origin proximal segment we have a occlusion at the distal sfa so about right here past the air-duct iratus plus another occlusion at the mid pop to talk about just again

the tandem disease baloney he also has a posterior tibial occlusion we talked about the fact that angio some concept so even if I treat all of this above I have to go after that posterior tibial to get to that heel wound and complement

the perineal so ways to reach analyze you know the the biggest obstacle here is on to the the occlusions i want to mention some of the devices out there I'm not trying to get in detail but just to make it reader where you know there's

the baiance catheter from atronics essentially like a little metal drill it wobbles and tries to find the path of least resistance to get through the occlusion the cross or device from bard is a device that is essentially or what

I call is a frakking device they're examples they'll take a little peppermint they'll sort of tap away don't roll the hole peppermint so it's like a fracking device essentially it's a water jet

that's pulse hammering and then but but to be honest I think the most effective method is traditional wire work sorry about that there are multiple you know you're probably aware of just CTO wires multi weighted different gramm wires 12

gram 20 gram 30 gram wires I tend to start low and go high so I'll start with the 12 gram uses supporting micro catheter like a cxi micro catheter a trailblazer and a B cross so to look at here the sheath I've placed a sheet that

goes into the SFA I'm attacking the two occlusions first the what I used is the micro catheter about an 1/8 micro catheter when the supporting my catheters started with a trailblazer down into the crossing the first

occlusion here the first NGO just shows up confirmed that I'm still luminal right I want to state luminal once I've crossed that first I've now gone and attacked the second occlusion across that occlusion so once I've cross that

up confirm that I'm luminal and then the second question is what do you want to do with that there's gonna be a lot of discussions on whether you want Stan's direct me that can be hold hold on debate but I think a couple of things we

can agree we're crossing their courageous we're at the pop if we can minimize standing that region that be beneficial so for after ectomy couple of flavors there's the hawk device which

essentially has a little cutter asymmetrical cutter that allows you to actually shave that plaque and collect that plaque out there's also a horrible out there device that from CSI the dime back it's used to sort of really sort of

like a plaque modifier and softened down that plaque art so in this case I've used this the hawk device the hawk has a little bit of a of a bend in the proximal aspect of the catheter that lets you bias the the device to shape

the plaque so here what I've done you there you can see the the the the the teeth itself so you can tell we're lateral muta Liz or right or left is but it's very hard to see did some what's AP and posterior so usually

what I do is I hop left and right I turned the I about 45 degrees and now to hawk AP posterior I'm again just talking left to right so I can always see where the the the the AP ended so I can always tell without the the teeth

are angioplasty and then here once I'm done Joan nice caliber restored flow restored then we attacked the the common for most enosis and sfa stenosis again having that device be able to to an to direct

that device allows me to avoid sensing at the common femoral the the plaque is resolved from the common femoral I then turn it and then attack the the plaque on the lateral aspect again angioplasty restore flow into the common firm on the

proximal SFA so that was the there's the plaque that you can actually obtain from that Hawk so you're physically removing that that plaque so so that's you know that's the the restoration that flow just just you know I did attack the

posterior tibial I can cross that area I use the diamond back for that balloon did open it up second case is a woman

you see again renal Dena Graham you can see a hint of the gonad of Ain selective

vena Graham again showing us the large gonadal vein and that's my post so charcoal with the occlusion balloon and then treat I showed the cartoon slide before that we look at all four of those territories so I always start with the

left but then I'm gonna look at the right gonadal vein as well as the internal iliac veins on both sides in this case the right go Natalie was normal as were the internal iliac veins so not seeing any varicosities

normal venous outflow so this patient it was only treated with a left gonadal vein embolization

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

so what what venous insufficiency is is really leaky valves so if you want to hit the play on that so that's all venous insufficiency that's what we

talked about it's it's leaky valves and so you can see this the valve leaflets there which are paper-thin is allowing blood to go the wrong way if you want to hit play on that one when we looked for valve

insufficiency for sure in the legs we use ultrasound and there's a bunch of different things that we look at an ultrasound you first look if you can augment blood flow so that was that first part we see if it's compressible

to make sure there's not a clot in it that's this part you can see the vein winking at you and then finally we look at valsalva or some type of way to determine if the valves are competent or incompetent and what this figure is

showing is that when a patient valsalva Zoar tenses up their abdominal muscles you see the gray line for the ultrasound crossing the access and going the opposite way all that means is it's got opposite directional flow which you

should not be able to do if your valves work so if your valves work you would not see that ultrasound picture crossing the line here it would just continue right there or would just stop and then flow would start again once you stop fel

salving so that's how we check in a leg but for pelvic venous insufficiency that's kind of hard to ultrasound the deep pelvic veins I could certainly look for varicosities with a an ultrasound of the pelvis but you can't really find the

source of an usually the source veins are the internal iliac veins or the gun at Elaine's and those are tough to ultrasound so secondary evidence of incompetence or leaky valves in those systems is varicosities

and so in the case of pelvic venous insufficiency those varicosities are in the pelvis and you see on the slide here you got varicose veins deep in the pelvis here and here and see some larger ones in that same

area on that CT scan so that'll tell us varicose veins that doesn't necessarily tell you whether the issue is with a gonadal vein or an internal iliac vein it just tells you that there are sequelae of varicosities much like in

the leg you might have varicose veins in the ankle but the problem is really higher up in the leg at this afterno femoral Junction so that gives us secondary evidence but it hasn't really told us the cause of the varicose veins

this is just a CT image that it also may show a large gonadal vein right here so you normally should not see it that big it's right there also secondary evidence that the valve is incompetent but it doesn't really test the valve itself

it's it just gives you the idea that veins enlarge and the valves gonna be leaky this is a cartoon schematic of the

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]

another device that's new in the market

is the inari device it is a combi combination of suction thrombectomy and mechanical thrombectomy and it you can see it looks like three Amplatz or plugs on a catheter but that blue catheter is actually a very nice suction system as

well so you can go beyond the clot pull it in and then suck it into the catheter this is very useful because you can pull clot out without giving any TPA and you have a lot less blood loss so if you can take the clot out with a lot less blood

loss I think you can out patients again the benefit is that there's no thrombolytic and the patients have less bleeding drawbacks like many of these devices is there's really no studies to prove that they work we can prove that

they can remove clot from the patient's body but that we don't know that that actually helps in the long run so what we really want to know in all the studies which we're actually going to show three of the main studies is

whether this actually helps patients life in the long term do they does it improve their mortality so the first

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

we're gonna move on to embolization there a couple different categories of embolization bland embolization is when

you just administering something that is choking off the blood supply to the tumor and that's how it's going to exert its effect here's a patient with a very large metastatic renal cell lesion to the humerus this is it on MRI this is it

per angiogram and this patient was opposed to undergo resection so we bland embolized it to reduce bleeding and I chose this one here because we used sequentially sized particles ranging from 100 to 200 all

the way up to 700 and you can actually if you look closely can see sort of beads stacked up in the vessel but that's all that it's doing it's just reducing the blood supply basically creating a stroke within the tumor that

works a fair amount of time and actually an HCC some folks believe that it were very similar to keep embolization which is where at you're administering a chemo embolic agent that is either l'p hi doll with the chemo agent suspended within it

or drug eluting beads the the Chinese have done some randomized studies on whether or not you can also put alcohol in the pie at all and that's something we've adopted in our practice too so anything that essentially is a chemical

outside of a bland agent can be considered a key mobilization so here's a large segment eight HCC we've all been here before we'll be seeing common femoral angiogram a selective celiac run you can make sure

the portals open in that segment find the anterior division pedicle it's going to it select it and this is after drug living bead embolization so this is a nice immediate response at one month a little bit of gas that's expected to be

within there however this patient had a 70% necrosis so it wasn't actually complete cell death and the reason is it's very hard to get to the absolute periphery of the blood supply to the tumor it is able to rehab just like a

stroke can rehab from collateral blood supply so what happens when you have a lesion like this one it's kind of right next to the cod a little bit difficult to see I can't see with ultrasound or CT well you can go in and tag it with lip

Idol and it's much more conspicuous you can perform what we call dual therapy or combination therapy where you perform a microwave ablation you can see the gas leaving the tumor and this is what it looks like afterwards this patient went

to transplant and this was a complete pathologic necrosis so you do need the concept of something that's ablative very frequently to achieve that complete pathologic necrosis rates very hard to do that with ischemia or chemotherapy

alone so what do you do we have a

and then one more example just to sort of illustrate the idea of a heat sink or

a cold sink right so this patient has a mass in their left adrenal gland right next to the aorta it's just anterior to the kidneys so the problem here is if you put a microwave ablation probe right next to the aorta you're likely to burn

the aorta and if you want to point the microwave ablation probe directly at the aorta well there isn't really a good window for that right you would have to go through the kidney you'll go through bowel and on route to getting there so

really I elected to do cryoablation right so that's the mass that's the aorta so you're obviously worried about injuring any order you place two probes into the lesion they obviously are streaking us out right now but that's

the aorta right there so we are four millimeters away from the aorta with these two probes you would think you'd be concerned about damaging it but using that cold sink effect you can see how the ice boss actually carves around the

aorta so you can get a really nice ablation on to that structure with that Waring that you're damaging the aorta or any nearby big vascular structure now that doesn't happen with pancreas if you freeze into pancreas you're going to get

a pancreatitis and if you freeze into bowel your bowel is going to have a perforation so that really just is with blood vessels that you can do that

artery embolisation work so I'm going to cut through this like like fancy words so basically what happens is because an infarction of the prostate that

decreases a lot of this excuse me it did subsequent cost is shrinker prostate by decreasing tht and hopefully will she's a prostate he also has to do with the innervation and decreasing the sensitivity of the alpha-1 receptors

which actually does is actually smooth the muscle around a process allowing urine to flow freely so just to give you an example even though patient has a prostate volume 150 grams mute if we were to

shrink it just a little bit it doesn't mean that their symptoms would be relieved actually because the smooth muscle relaxation around the prostate a lot of the symptoms may actually get better so this this procedures indicated

for some of us who may be at high risk for any surgical procedure someone who's refractory to medical therapy or does not want to consume medical therapy or someone who obviously hat with a high IPSS score

the thing with PAE is obviously technically it's very challenging because as you go under proceed the artists get smaller and smaller so you have to consider the elderly who may have some atherosclerosis disease and

there's also risk of non-target embolization where we could potentially embolize the penis or the bladder or direct them as far as strict factors we want to consider patients age someone has diabetes chronic renal failure we

want to make sure that patient doesn't have any recent infection stones or any instrumentation regarding their neurological system so what are the

now other causes this is a little bit different different scenario here but it's not always just as simple as all

there's leaky valves in the gonadal vein that are causing these symptoms this is 38 year old Lafleur extremity swelling presented to our vein clinic has evolved our varicosities once you start to discuss other symptoms she does have

pelvic pain happiness so we're concerned about about pelvic congestion and I'll mention here that if I hear someone with exactly the classic symptoms I won't necessarily get a CT scan or an MRI because again that'll give me secondary

evidence and it won't tell me whether the veins are actually incompetent or not and so you know I have a discussion with the patient and if they are deathly afraid of having a procedure and don't want to have a catheter that goes

through the heart to evaluate veins then we get cross-sectional imaging and we'll look for secondary evidence if we have the secondary evidence then sometimes those patients feel more comfortable going through a procedure some patients

on the other hand will say well if it's not really gonna tell me whether the veins incompetent or not why don't we just do the vena Graham and we'll get the the definite answer whether there's incompetence or not and you'll be able

to treat it at the same time so in this case we did get imaging she wanted to take a look and it was you know shame on me because it's it's a good thing we did because this is not the typical case for pelvic venous congestion what we found

is evidence of mather nur and so mather nur is compression of the left common iliac vein by the right common iliac artery and what that can do is cause back up of pressure you'll see her huge verax here and here for you guys

huge verax in that same spot and so this lady has symptoms of pelvic venous congestion but it's not because of valvular incompetence it's because of venous outflow obstruction so Mather 'nor like I mentioned is compression of

that left common iliac vein from the right common iliac artery as shown here and if you remember on the cartoon slide for pelvic congestion I'm showing a dilated gonna delve a non the left here but in this case we have obstruction of

the common iliac vein that's causing back up of pressure the blood wants to sort of decompress itself or flow elsewhere and so it backed up into the internal iliac veins and are causing her symptoms along with her of all of our

varicosities and just a slide describing everything i just said so i don't think we have to reiterate that the treatments could you go back one on that I think I did skip over that treatments from a thern er really are also endovascular

it's really basically treating that that compression portion and decompressing the the pelvic system and so here's our vena Graham you can see that huge verax down at the bottom and an occluded iliac vein so classic Mather nur but causing

that pelvic varicosity and the pelvic congestion see huge pelvic laterals in pelvic varicosities once we were able to catheterize through and stent you see no more varicosity because it doesn't have to flow that way it flows through the

way that that it was intended through the iliac vein once it's open she came back to clinic a week later significant improvement in symptoms did not treat any of the gonadal veins this was just a venous obstruction causing the increased

pressure and symptoms of pelvic vein congestion how good how good are we at

very helpful these patients the calcium this and the vessels can be

seen through with the MRA it doesn't it doesn't cause as much artifact so it could be easier to see what's going on in calcified vessels additionally you saw an image in Marc's talk as well of this is an example of a time-resolved

image of an MRA or you can basically recreate exactly what you're seeing in an angiogram and this could be very helpful to kind of determine what kind of TVL disease you're getting yourself into

newer MRI techniques that we're using in the evaluation patients with PID functional MRI which compares the ratio of how much oxygen versus deoxygenated hemoglobin we have in a tissue so we can apply this to a pre and post exercise

scenario in patients to have claudication as well although it's not it's only approved in research protocols this is an example of what you see for that so pre intervention here's the CTA image reconstruct

in 3d with a long segment an iliac occlusion and then post intervention you can see there's a standard reconstructed vessel and the you can both chart this out and do it and superimpose it on the MRA image and you're gonna get an actual

quantitative amount of tissue reperfusion but studies are still ongoing to determine just how much increasing the amount of red that's in that image is important we don't know the answer to that yet here's just

another example a patient underwent an anterior tibial artery recanalization and you can see the improvement in the t2 star which is just one of the one of the measurements that you can use on these images so what's on the horizon

next is me talking about Egypt and Ethiopia and how I are how IRS practice in Egypt and Ethiopia and I think feather and Musti is gonna talk a little bit about Ethiopia as well he's got a

lot of experience about in about Ethiopia I chose these two countries to show you the kind of the the the the difference between different countries with within Africa Egypt is the 20th economy worldwide by GDP third largest

economy in Africa by some estimates the largest economy in Africa it's about a hundred million people about a little-little and about thirty percent of the population in the u.s. 15 florist's population worldwide and has

about a little over a hundred ir's right now 15 years ago they had less than ten IRS and fifteen years ago they had maybe two to three IRS at a hundred percent nowadays they're exceeding a hundred IRS so tremendous gross in the last 15 years

in the other hand Ethiopia is a very similar sized country but they only have three to five IRS that are not a hundred percent IRS and are still many of them are under training so there are major differences between countries within

within Africa countries that still need a lot of help and a lot of growth and countries that are like ten fifteen years ahead as far as as far as intervention ready intervention radiology

most of the practice in Ethiopia are basic biopsies drainages and vascular access but there is new workshops with with embolization as well as well as well as vascular access in Egypt the the ir practice is heavily into

interventional oncology and cancer that's the bulk that's the bulk of their of their practices you also get very strong neuro intervention radiology and that's mostly most of these are French trained and not

American trains so they're the neuro IRS in Egypt or heavily French and Belgian trains with with french-speaking influence but the bulk of the body iron that's not neuro is mostly cancer and it involves y9e tastes ablations high-end

ablations there's no cryoablation in Egypt there is high-end like like a nano knife reverse electric race electroporation in Egypt as well but there is no cryo you also get a specialty embolization such as fibroids

prostate and embroiders are big in Egypt they're growing very very rapidly especially prostates hemorrhoids and fibroids is an older one but it's still there's still a lot of growth for fibroid embolization zyou FES in Egypt

there's some portal portal intervention there's a lot of need for that but not a lot of IRS are actually doing portal intervention and then there's nonvascular such as billary gu there's also vascular access a lot of

the vascular access is actually done by nephrology and is not done by not not done by r is done by some high RS varicose veins done by vascular surgery and done by IRS as an outpatient there's a lot of visceral angiography as well

renal and transplants stuff so it's pretty high ends they do not do P ad very few IR s and maybe probably two IR s in the country that actually do P ad the the rest of the P ad is actually endovascular PA DS done by vascular

surgery a Horta is done all by vascular surgery and cardiothoracic surgery it's not done it's not done by IR IR s are asked just to help with embolization sometimes help with trying to get a catheter in a certain area but it's

really run by by vascular surgeons but but most more or less it's it's the whole gamut and I'm going to give you a little example of how things are different that when it comes to a Kannamma 'kz there's no dialysis work

they don't do Pfister grams they don't do D clots the reason for that is the vascular surgeons are actually very good at establishing fishless and they usually don't have a

lot of problems with it sometimes if the fistula is from Beau's door narrowed it's surgically revised they do a surgical thrombectomy because it's a lot cheaper it's a lot cheaper than balloons sheaths and and trying to and try a TPA

is very expensive it's a lot cheaper for a surgeon to just clean it out surgically and resuture it there's no there's no inventory there are no expensive consumables so we don't see dialysis as far as fistula or dialysis

conduits at all in Egypt and that's usually a trend in developed in developed countries next we'll talk

different applications renal ablation is very common when do we use it

high surgical risk patients primary metastatic lesions some folks are actually refused surgery nowadays and saying I'll have a one centimeter reno lesion actually want this in lieu of surgery people have

familial syndromes they're prone to getting a renal cancer again so we're trying to preserve renal tissue it is the most renal parenchymal sparing modality and obviously have a single kidney and a lot of these are found

incidentally when they're getting a CT scan for something else here's a very sizable one the patient that has a cardiomyopathy can see how big the heart is so it's you know seven centimeter lesion off of the left to superior pole

against the spleen this patient wouldn't have tolerated bleeding very much so we went ahead and embolized it beforehand using alcohol in the pide all in a coil and this is what it looks like when you have all those individual ice probes all

set up within the lesion and you can see the ice forming around I don't know how well it projects but in real time you can determine if you've developed your margin we do encompass little bit of spleen with that and you can see here

that you have a faint rim surrounding that lesion right next to the spleen and that's the necrotic fat that's how you know that you got it all and just this ablation alone caused a very reactive pleural

effusion that you can see up on the CT over there so imagine how this patient would have tolerated surgery pulmonary

new data of the Emmy trial that came out last year our ten-year results saying

that after ten years after ten years women who wanted to retain their uterus they looked at them in ten years three-quarters of those women were still very very satisfied and also were still able to retain their uterus so ten-year

data came out randomizing people for uterine artery embolization versus hysterectomy of the women who chose you to an artery embolization ten years later they were still very happy so I tell my patients that this is what you

should expect that you will have symptomatic improvement in 12 months around 85 to 95 percent of the patients are pretty happy there is a entry intervention rate it is not zero and it can be higher than ten

depending on what kind of Imogen is seen ahead of time and that we know that dysfunctional uterine bleed tend to do a little bit better than bulk type symptoms and that's partly because of subjective nature of that so this is one

of the patients that I treated when I was in in Virginia and Riverside and she's a former miss Brazil and she came to see us with what she also called reversed cycles like she would bleed more than she would not and she was

wearing depends and it took everything to just coach her out of the car to come inside to do a consultation because she was so afraid that if she got out she would be sitting in a pool of blood and she had an MRI showing what looked like

a eleven point seven centimeter fibroid she had embolization and that was her six month follow-up MRI to the right which looks like a very impressive result they don't all look this way which is why I save this image something

that looks like a normal uterus now I for the persons that I told to hold your high horse here is the time okay so what happens if I want to have a baby because these are the things you remember we're being ambassadors for this procedure we

need to be having the answers for the things that are our friends and family members are going to be asking us so if you want to have a baby I would say that the data that informs us as to what to do with you is still very weak but the

only randomized prospective trial that we have out there says that you should actually have myomectomy and a Cochrane review was also done and it still says that there's very low level evidence suggesting that myomectomy may be

associated with better fertility outcomes as opposed to UAE but more research is needed and we still require more research so at the very least what I have to do and now you feel compelled to do is to send my patients to see

someone who is a fertility specialist in consultation so we can make this decision together so if your poor surgical candidate if you have the gazillion fibroids and if you've had surgery before a hostile

abdomen and the patient says you know what dr. Newsome there's nothing that you can tell me ever to say that I'm going to have surgery then we're going to be doing something else that is not surgery okay the other thing that your

are just a couple examples you know this is a little bit of older data but our uterine fibroid embolization have gone up by 60 percent from when we started to where we are now or filter retrieval

program gone up by 400 percent you know our ablations have gone up by over 50% you know and that's it's not saying that's all because of social media but it's partially because of that because we do get patients that come into our

clinic because of that and then on top of that I'll tag when I'm doing an ablation I'll tag my urologist or I'll tag de aslv you know and then all of a sudden sometimes they like it which pushes it to their followers or they'll

retweet it which directly pushes it to their followers and then in which case you're putting yourself in the consciousness of people that can refer you cases and all of a sudden now you become indispensable in the realm of

ablation at least in my case because everybody sees me posting about it right so everybody in our institution is sending me ablation cases and that's a really great thing for us so you know I

know we're running a bit short on time so I want to briefly just touch about

some techniques with comb beam CT which are very helpful to us there are a lot of reasons why you should use comb beam CT it gives us the the most extensive anatomic understanding of vascular territories and the implications for

that with oncology are extremely valuable because of things like margin like we discussed here's an example of a patient who had a high AF P and their bloodstream which tells us that they have a cancer in her liver we can't see

it on the CT there but if you do a cone beam CT it stands up quite nicely why because you're giving levels of contrast that if you were to give them through a peripheral IV it would be toxic to the patient but when you're infusing into a

segment the body tolerates at the problem so patient preparation anxa lysis is key you have them exhale above three seconds prior to that there's a lot of change to how we're doing this people who are introducing radial access

power injection anywhere from about 50 to even sometimes thirty to a hundred percent contrast depends on what phase you're imaging we have a Animoto power injector that allows us to slide what contrast concentration we like a lot of

times people just rely on 30% and do their whole the case with that some people do a hundred percent image quality this is what it looks like when someone's breathing this is very difficult to tell if there's complete

lesion enhancement so if you do your comb beam CT know it looks like this this is trying to coach the patient and try to get them to hold still and then this is the patient after coaching which looks like this so you can tell that you

have a missing portion of the lesion and you have to treat into another segment what about when you're doing an angio and you do a cone beam CT NIT looks like this this is what insufficient counts looks like on comb beam so when you see

these sort of Shell station lines that are going all over the screen you have to raise dose usually in larger patients but this is you know you either slow down the acquisition speed of your comb beam or

you raise dose this is what it looks like after we gave it a higher dose protocol it really changes everything those lines are still there but they're much smaller how do you know if you have enhancement or a narrow artifact you can

repeat with non-contrast CT and give the patient glucagon and you can find the small very these small arteries that pick off the left that commonly profuse the stomach the right gastric artery you can use your comb beam CT to find

non-target evaluation even when your angio doesn't suggest it so this is a patient they have recurrent HCC we didn't angio from here those arteries down there where those coils were looked funny even though the patient was

quote-unquote coiled off we did a comb beam CT and that little squiggly C shape structures that duodenum that's contrast going in it this would be probably a lethal event for the patient or certainly would require surgery if you

treated that much with y9t reposition the catheter deeper towards the lesion and you can repeat your comb beam CT and see that you don't have an hands minh sometimes you have these little accessory left gastric artery this is

where we really need your help you know a lot of times everyone's focused and I think the more eyes the better for these kind of things but we're looking for these little tiny vessels that sometimes hop out of the liver and back into the

stomach or up into the esophagus there's a very very small right gastric artery in this picture here this patient post hepatectomy that rides along the inferior surface of the liver it's a little curly cube so and this is a small

esophageal branch so when you do comb beam TT this is what the stomach looks like when it enhances and this is what the esophagus looks like when it enhances you can do non contrast comb beam CTS to confirm ablation so you have

a lesion this is the comb beam CT for enhancement you treat with your embolic and this is a post to determine that you've had completely shin coverage and you can see how that correlates a response so the last thing we're going

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

typical symptoms if you want to hit the play on this I think this is one we've probably already seen but it's it's the the algorithm that I go through for treatment so we do my renal vena Graham

there we go it's classic definitely has reflux and so next I will selectively catheterize the gonadal vein and here you see very large pelvic varicosities and so my standard is to actually treat the varicose veins with a sclerostin

much like I would sclerosis a varicose vein in the leg and there's a few reasons that I do that and so here's how I do it I'll put an occlusion blown up you see the picture on the left of the screen has an occlusion balloon it's the

same occlusion balloon we use for a tips procedure and I'll temporarily block the gonadal vein and fill up the system or the varicosities with contrast so that I get a sense for the volume of sclerosis and I would use then the picture on the

right is a venogram after I've injected the sclerostin so I've evaluated the volume and then I've replaced all that contrast by forcing it through the system to drain out the pelvic veins and filling the varicosities with

soldier column I do that because I believe and there's no data to prove it that it helps prevent superficial phlebitis in those varicosities so if we're just gonna block off the gonna dull vein then we have stagnant blood in

all the pelvic varicosities and stating that blood wants to clot and when blood clots on its own it'll stretch and expand the vein and cause pain and so in my own personal experience that has created a little bit worse post

procedural symptoms for patients compared to the patients that I use so TRADOC all to actually treat the varicosities so that's what I start out with and then since I'm kind of an old-fashioned guy I still go with the

coils and so I coiled the whole going a ttle vein and you can use sort of whatever you want you know that's the simplest thing for me are using nester coiours coils and and fill it up some people use the long detachable shaping

coils kind of an expensive way to do it if it saves you radiation then then that's that's one of the reasons to do it but the point is in in the venous system you have to be able to and I show this slide because you can see a

collateral vein or at least a branch there a confluence point that we've coiled off too if you do not treat the entire length there's a there's a lot higher chance for recurrence and veins have a way to find their way around if

they can communicate back up then patient gets recurrent symptoms and that can happen in about ten percent of cases so in order to prevent that you treat the whole gun out of vein and that's sort of why I think some people like to

use liquid sclerosis because then they will be able to sort of profuse all those branch points that would have a chance for recurrence case number two

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

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 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

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

to talk about is indirect angiography this is kind of a neat trick to suggest to your intervention list as a problem solver we were asked to ablate this lesion and it looked kind of funny this patient had a resection for HCC they

thought this was a recurrence so we bring the comb beam CT and we do an angio and it doesn't enhance so this is an image here of indirect port ography so what you can do is an SMA run and see at which point along the

run do you pacify the portal vein and you just set up your cone beam CT for that time so you just repeat your injection and now your pacifying the entire portal vein even though you haven't selected it and what to show

well this was a portal aneurysm after resection with a little bit of clot in it the patient went on some aspirin and it resolved in three months so back to our first patient what do you do for someone who has HCC that's invading the

heart this patient underwent 2y 90s bland embolization microwave ablation chemotherapy and SBRT and he's an eight-year survivor so it's one of those things where certainly with the correct patient selection you can find the right

things to do for someone I think that usually our best results come from our interdisciplinary consensus in terms of trying to use the unique advantages that individual therapies have and IO is just one of those but this is an important

lesson to our whole group that you know a lot of times you get your best results when you use things like a team approach so in summary there are applications to IO prior to surgery to make people surgical candidates there are definitive

treatments ie your cancer will be treated definitively with curative intent a lot of times we can save when people have tried cure intent and weren't able to and obviously to palliate folks to try to buy them time

and quality of life thermal ablation is safe and effective for small lesions but it's limited by the adjacent anatomy y9t is not an ischemic therapy it's an ablative therapy you're putting small ablative radioactive particles within

the lesion and just using the blood supply as a conduit for your brachytherapy and you can use this as a new admin application to make people safer surgical candidates when you apply to the entire ride a panic globe

thanks everyone appreciate it [Applause] [Music]

so what does the future hold for us we would like to do more complex procedures right now we're doing why 90s after all

we built a hot lab we have radiation safety who's coming to our site on Mondays nuke med is also involved with that we've done for successful procedures so far so that was a big win for us we're also doing prostate artery

embolization which is new for our Center too which is also great we want to do anything that's safe and profitable essentially and we don't also maybe consider publishing our safety data to increase the available public data and

hope for better reimbursement rates so that was us a year in after everything that we had endured were still smiling we have a good time together I think they might kill me if they knew this picture was in my presentation so those

who know them please don't tell them but yeah we're still enjoying it there and that concludes my presentation

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

- [Lu Qingsheng] I have no disclosures. We know for indication of EVAR we need favorable proximal neck anatomy but if it not unfavorable maybe we are some Type 1a endoleak it's a serious complication for EVAR. So for prevent and treat Type 1a endoleak

especial for some juxtarenal aneurysm maybe we use the chimney fenestration branch and some sac bag. Could we find a simple safe cheap and effective method? So we find from open surgery we were introduced this fibrin glue

means its complex of thrombin and fibrinogen, it's used hemostasis in open surgery so we put that into inject that into the sac, we call it fibrin glue sac embolization. I will show you some cases.

For this case is very short neck and not quality of deck and after deploy the stent graft, of course very serious Type 1a endoleak. But fortunately, we put a catheter before we deploy the stent graft so this catheter is into the sac of the aneurysm

then we use up a long controlled blood flow and we inject from the catheter into the sac of the aneurysm and we inject the fibrin glue. And you can find the contrast not moved after we withdraw balloon. Then we do the angiogram.

We find no any endoleak. Another case showed is angulated neck as this patient. Of course after we deployed stent graft have a lot of endoleak. And we do again this technique. And control the balloon, control the blood flow,

then inject the fibrin glue, and we check all that and withdrew the balloon, there are no any movement about the sac. And we do the angiogram and no any endoleak. Till now, we did, we begin this technique 2002, so we follow long time that we can show it's safe.

So till now we treat 156 cases and proximal less then short proximal neck is 75 cases even some of less than 10 millimeters. And angulation more than 60 degree even some cases more than 75 degree.

Most of them more than 98% of patients' endoleak was resolved. And during our follow up, the mean time more than 100 months, only three patients died of aneurysm related sac enlargement.

The mean maxim aneurysm diameter decreased and no recurrent Type 1 endoleak so we have confidence that it's safe and no any sealant-related complication for example renal failure and aplasia other things. So we discuss the mechanism

it's not only embolization for endoleak but also coagulating all sac of aneurysm like this in shows how it worked. And we also measure the pressure in the sac. Intrasac pressure decreased significantly in treated cases. And how about that technique we need occlusion

proximal blood flow and protect branch ateliers and prevent distal embolization. And we also treated into the rupture aneurysm and it can treat any type of endoleak as these cases it's a rupture aneurysm we do the EVAR emergency.

And after we deploy this devices, we find this endoleak. We don't make sure which kind of endoleak but anyway we just do that, control the blood flow use the balloon then inject the fibrin glue in that.

And all the sac of aneurysm. Then we do the angiogram and endoleak disappeared. We'll be treat any type endoleak of the rupture EVAR we prevent rupture post-EVAR and we decreased abdominal compartment syndrome. So the conclusion is

fibrin glue sac embolization is a simple and effective treatment method. And this method could expand the current indication of EVAR. For selective the length maybe can to the 5 millimeters, angle maybe can to the 90 degree,

and for emergency we seen it should be into the older EVARs for rupture aneurysms. Thank you very much.

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
