Transcript

okay so uh what about the variations well the ovarian arteries I indicated are that most common source of additional supply the uterus and depending upon the study you look at how is detected its around

two three four percent something like that but there are some other potential sources there's the round ligament artery we talked about that th mesenteric occasionally we'll have a

collateralized or parasitize branches omental branches lumbars and occasionally pelvic sidewall branches and so we're going to show some of these examples so first I have sort of my own

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

so why staging important well when you go to treat someone if I tell you I have a lollipop shaped tumor and you make a lollipop shape ablation zone over it you have to make sure that it's actually a lollipop shaped to begin with so here's

a patient I was asked to ablate at the bottom corner we had a CT scan that showed pretty nice to confined lesion looked a little regular so we got an MRI the MRI shows that white signal that's around there then hyperintensity that's

abnormal and so when we did an angiogram you can see that this is an infiltrate of hepatocellular carcinoma so had I done an ablation right over that center-of-mass consistent with what we saw on the CT it

wouldn't be an ablation failure the blasian was doing its job we just wouldn't have applied it to where the tumor actually was so let's talk about

we know try to make this painless but I think it's kind of interesting

so metabolism is just talking about converting a medication into a less or more active form and that gets converted into what we call metabolites within metabolism you have your cytochrome p450 system which is responsible for

metabolism of a lot of the drugs that we give and essentially that's just a family of enzymes that are responsible for metabolism properties are going of the drug are going to influence the duration of action and the half-life of

your medication so for instance of a pee if a drug is highly protein bound what it does when you administer it is it binds to the protein molecules and slowly dissociates so you have a longer duration of action

because when it's bound to the protein it's in active half-life again any properties that increase the duration of action are going to be something we want to pay attention to and how is the drug excreted you can have excretion through

the bile feces renal system a big thing I think for us and IR is drugs that are really excreted benzodiazepines are the mainstay in providing the sedative component a procedural sedation it's going to enhance the inhibitory effect

of the gaba neurotransmitter in the central nervous system why do we care about that does anyone know have something to do with our reversal so our gaba neurotransmitter is responsible for inhibiting the activity

in the brain so if we didn't have a gaba neurotransmitter we would have seizures all day patients who have seizure history of seizure disorder are sometimes on benzodiazepine therapy at home if you sedate them and they require

reversal and you give them flemeth know you can potentially precipitate a seizure so it's just something you want to keep in the back of your mind it doesn't mean you're not going to reverse them you just want to be prepared to

handle a seizure if that occurs versed is our number one drug that we use onset of action and peak effect or seen in 3 to 5 minutes the antagonist as I mentioned is flumazenil and the half-life is three

hours typically in our department we give one milligram depending on the patient's physical condition and what they require and how anxious they are we may give 0.5 or up to two in one dose now you're gonna see and an Aaron says

this to in their procedural sedation guideline that you shouldn't exceed five milligrams I don't complete and that means overall in one case I don't completely agree with that I'll explain more why later but I think patients are

really complex and there can be a lot of drug interactions that are occurring that may cause them to require more sedation than a typical patient so it's not so cut and dry you could look at five milligrams and go that's kind of

more than the norm and maybe I need to look at is the sedation not working but you may have a patient that could take 10 11 12 milligrams of versed and be

ablating things in the bones well musculoskeletal blasian we're fortunate within our practice that we have a doctor councilman Rochester who's

a probably one of the biggest world's experts on this and these are his cases that he shared but you can see when you have small little lesions and bones that are painful you can place probes in them and you freeze them the tumor dies and

musculoskeletal things remain intact what about when you have cases like this where there's a fracture going through the iliac bone on the left with an infiltrate of malignancy well you can cryo blade it and what's cool about is

you can using CT guidance do percutaneous cannulated pins and screws and a cement o plasti ver bladed cavity and when you're done the patient who initially couldn't walk now can and whose pain scale went down to one so I

think that's that's very important to realize the potential of image-guided medicine this is something that previously would have had to been done in the orthopedic lab so you know I think this is extending options where

otherwise it would have been difficult same thing applies to the spine you can ablate and fill them with cement so

patient like this you have a very large left lateral HCC that's invading the left the patek vein and extending into the heart since when we get into things like radioembolisation if you have

multifocal liver disease if you want to apply radiation therapy to that's very difficult to do that because it actually requires more radiation dose to kill HCC than it does the adjacent normal liver the liver is actually that ready

sensitive so you can do things like SBRT and pick an individual lesion you can do things like a imrt which is you know survey 8 non focus generalize low dose but what's interesting Malaysian is that if you administer

particles they only shoot about two millimeters worth of the raishin field around it so of what used is that with one not much but if you put eight to forty million of them within the bloodstream they Auto sort themselves

based off of the vascular flow preferential that exists with tumors tumors actually emit hormones pull in blood supply that you weren't born with and that actually tends to pull beads from the bloodstream preferentially

towards it so this is an example where you stain a tumor with two types of wax one the portal that's blue one the artery that's red and you can see how much that preferential exists so what ends up happening is these spheres

cluster within the tumor and then provide local dose radiation that's very hot where the tumor is and low elsewhere so here's an example of that this is a patient with metastatic neuroendocrine disease multifocal liver lesions you can

see that vascular flow preferential this is what it looks like on the maa when we jecht a protein particle surrogate that has a technician I should have assigned to it just as a visualization of how the particle is

going to sort out and the post y9t bremsstrahlung CT is over there and you can see how intense the necrosis is within the tumor and how much it's spared the normal liver however you do get some radiation damage they don't

live a regardless that's why choosing the timing of when you're gonna do this is important this is a patient that was treated with tastes above and one session of y9u beneath so you can see that they do have different types of

therapeutic mechanisms they're not the same even though they look very similar in terms of when we're administering

gets pet MRIs right now our main focus are our oncology patients it helps us

determine the type of cancer they have the diagnosis of cancer assess disease progression treatment therapy and treatment planning and some antecessor treatment response so let's say a lesion is FDG avid and

has low blood perfusion that would help our physicians to us to say what kind of treatment they can give to the patient pet MRI is also good for patients who can tolerate longer scans right now it's a very young modality

there's still a lot of research goes on with this and coupled with that is advantage of research right now we actually in the Memorial sloan-kettering we have started using this instead of FDG we've used gallium 68 of to assess

neuroendocrine tumors who have also done cervical lymph Austin Tiger phim where FDG is injected directly at the patient's cervical cavity and that helps map out the lymph nodes in the survey in the pelvic area this can be used by the

surgeon and see what lymph nodes can be sampled during the surgery we provide some education and assessment before during and after the pet MRI we assess for the patient's allergies we tell the patient's they have to be NPO at least

six hours prior to FDG injection as for our anxious patients they often come pre-medicated and this just comes with some care coordination with their physician the physician would prescribe some low-dose anti-anxiety medications

and the patient would take it an hour before their test as for our claustrophobic patients we what we have done is we let them see the Machine we let we let them feel the Machine we put them inside if they would want to and it

would be up to them if they would be tolerating the scan we assess for their diabetes regimen and my refe will speak more about that later we assess for patients pregnancy status on patients loving to fifty years old process for

their breastfeeding status and screen their implants during the pet MRI we tell them about the coil placement we give them an emergency call bell and we tell them to decrease their movement well being is like although our some of

our patients would say I didn't move but then the image so differently there there's a possibility that the magnet can induce some involuntary twitching after the MRI we tell them that they can resume their

diet they can resume their diabetic diabetes regimen and as if they get MRI contrast they can pump and dump for about 24 hours after the test but if they don't get a contrast they can keep their breast milk inside the fridge just

to help to decay just to decay the isotope that was given to the patient it doesn't give any harm to the baby

so my name's Heather I'm a nurse in interventional radiology at NYU Langone health in New York and I am the clinical resources for our department so what that means is I'm responsible for individualizing our education to meet the needs of our department and one of

the first things I wanted to look at when I took on the role was our procedural sedation practices and how we can improve by enhancing our knowledge this presentation includes many of the lessons and concepts that I learned

along the way that I think are really important to understanding how to effectively administer procedural sedation so our learning objectives are going to be a review of the guidelines pre-procedure assessment components

including airway assessment pharmacology of the medications that we give and intra procedure assessment so this is the 2018 AAS a practice guidelines for a procedural sedation by non anesthesiologist has everyone seen this

good great as so this is especially important because as you'll see the American College of Radiology and Society of interventional radiology were involved in its development so this is our guideline and I think it's really

important to look at this look at the practice recommendations and see how they align with your own practice and if there may be some changes you need to make first thing you always want to look at when you're reviewing any sort of

literature whether it's evidence-based guidelines or maybe just a review article is you want to look at the methodology that the author used to create the guideline so anybody know why that's important you just shout it out

so if I want to write a guideline for procedural sedation I could find a bunch of studies or review articles that fit my point of view and use them throw them at the bottom and that would be that but even if I use for an demise control

trials which are considered the gold standard of experimental research those randomized controlled trials could be poorly constructed randomized controlled trials so they may have introduced bias at some point into the study

that's skewed the outcome and the findings so you really want to make sure that the authors of the guideline that you're looking at appraise the research that they're using to support their recommendations and that's what the

aasa' task force did so they used randomized control trials and observational studies and then they categorize the strength and the quality of the study findings so as you're going through you'll see that statistically

significant was deemed a p-value of less than 0.01 and outcomes were designated as either beneficial harmful or equivocal equivocal meaning this findings were not significant one way or the other and then they also used

opinion based evidence from experts so they surveyed members of their task force and they did take into account some informal opinion from message boards and letters to the editor so I think a good example here is one of

their recommendations about capnography so they did a meta-analysis of randomized control trials that indicated that the use of continuous and title carbon dioxide monitoring was associated with a reduced frequency of hypoxemic

events when compared to monitoring without capnography and then you'll see at the end of the recommendations this category so for this particular recommendation they labeled it as category a1 - B evidence and what that's

telling you as category a means it was a randomized control trial which is great it was a level one meaning it's a high level of strength and quality and B is telling you that there was statistically significant findings that demonstrated

benefit to the patient now another recommendation that you may see as you're reading through would be the NPO guidelines so if you look at any of the literature about NPO recommendations it's really all expert

opinion because all of the evidence has shown equivocal findings so for example one of the studies they looked at compared the outcomes of patients who had clear liquids one hour prior to the procedure versus two hours and they

found no change in the outcome I think it's important when you're a provider and you're looking at that because you're gonna base your judgment calls on the evidence so you may have a patient come in who had tea up until one hour

prior to their procedure and you have to make a decision whether or not you want to cancel or proceed and you could look at the findings of the literature that shows that there really hasn't been a proven difference in outcomes so you may

decide to just do the procedure versus capnography there's very strong evidence showing it's beneficial to the patient always so I think this is a real big take-home point of why we do everything we do about procedural sedation all of

our assessments and enhancing our practice as a sedation is a continuum and practitioners intending to produce a given level of sedation should be able to rescue the patients whose level of sedation becomes deeper than initially

intended pre-procedure our assessment

in providing the analgesic component of procedural sedation they activate opioid receptors in the brain and spinal cord to inhibit transmission of painful impulses fentanyl is the main drug that

we use the onset of action is seen in one to three minutes and the peak effect is seen in five to fifteen the half-life is two to four hours and we typically give a dose of 50 mics to start again it's metabolized by that cyp3a4 what's

especially I think important to note is that it gets metabolized to inactive metabolites so I had a situation when I was a newer nurse I was working in the ICU I had an elderly patient it was my third night with her and she was

admitted for acute kidney injury related to her urosepsis so she really wasn't making a lot of urine and she lives in an incredible amount of pain she has been screaming for two nights and I finally said enough I went to the

resident so we have to give her something so she said let's give her some morphine you want to give her one milligram she's elderly can we at least start with 0.5 and see how she does with that she said that's fine I gave her the

point for five of morphine and she went to sleep maybe thirty minutes later and she looked really comfortable now we didn't we don't or at that time we didn't use capnography for non intubated patience in my ICU I was in but she did

have a pulse oximeter on and all the other monitoring I didn't really disturb her throughout the night I knew she hadn't slept in two days so I would go in and check on her and turn her and see how she was doing and she seemed really

asleep but comfortable I go and do my bedside handover with the day nurse in the morning we go to wake her up and she's not waking up and we do a really good sternal rub and all your nail bed pressure and all those tricks

and nothing's working and she's she's out so we called in the attending in the resident and pees and they ended up doing an arterial blood bath and her paco2 was 75 yes so they did give her narcan and thankfully it worked and she

didn't require intubation the nurse practitioner pulled me over afterwards when things had settled down she said you know I want to talk to you about what happened why did you decide to give her morphine and start a fentanyl and I

said well you know morphine of aura fentanyl rather is a hundred times more potent than morphine and I thought I was doing the right thing because she's an elderly patient I was worried about her cuz she's frail but then she explained

to me that morphine gets metabolized to several different metabolites and one of them is actually 2 to 3 times more potent than the original morphine that you're giving in the IV and because she was in acute renal failure she wasn't

excreting the drug so she had this two to three times more potent drug just circulating around her system all night which led to her respiratory depression and her hypercarbia with fentanyl you have metabolism to inactive metabolites

so it's considered to be more safe for patients who are in renal failure that was a real big aha moment for me because there's a lot that you have to know when you're a nurse especially if you're working in a critical care area and you

hope that you're the providers you're working with are thinking of these things but they're also very stressed so it's all of our responsibilities to know the way that these drugs work and I think it's great in IR because we we

don't give it a lot of medications we give a fair amount but they're pretty much the same medications over and over so we do have an opportunity to really take a better deep dive and really the mechanism of action and their

pharmacokinetic properties considerations you do want to consider renal e impaired patients because it can alter the kinetics meaning that there's decrease protein binding as I said for versed but there is they are slightly

less protein bound than versed and there is a black box warning for cyp3a4 inhibitors specifically for fentanyl just something to keep in mind when you're giving it though I think this is really more I'm talking about patients

that are going home with a fentanyl patch you want to make sure they're not taking inhibitors at home kind of

study I would like to share to you in personal note that my training school

books and experiences never prepared me for all the different types of cancer I have seen while working at Memorial sloan-kettering I have come to realize that cancer does not discriminate it doesn't matter how old you are

socioeconomic status gender race color of your skin and geographical location and religious beliefs and taking care of the young pediatric patients makes me the saddest if cancer hits you it hits you

the youngest patient that ever took care of is two months old infant diagnosed with glioblastoma I remember that day clearly because I booboo the whole day based on this here comes the third case study this is a four year old child

diagnosed with hepatoblastoma a pet MRI with anesthesia is done the image to your left is pet and on the right is pet MRI you see the difference in the images this scan is done for the doctor to evaluate the extent of the disease you

could see there is a hypermetabolic uptake in the liver and in the pelvic area the color red on top of the head the patient that's normal that's a normal uptake there is no increase in the uptake so this considered normal

we're gonna do our closer look and I would like to show you the difference between the PET CT and the pet MRI the image on the middle is the PET CT done on March you could see how where are the areas that are you could see all the

increased uptake on the areas like the chest the neck thoracic region and the abdominal region the the bright area there at the bottom Dustin or my bladder up take look at the image on to your right that's a close-up loop of the

sagittal PET CT done on same month you could see clear I could see where the location of the abnormal act uptake are circled by the the white circle there is abnormal uptake in the spine and in the chest and

of course where the hepato blastoma is located but looking to your left that's the bet MRI you see how the image is so clear and defined you could now count from the you could count where the exact location is it's on T 11 and is in the

vertebra and there's evidence of the actual cord compression with all you know all you know is a neuro emergency this is a four year old child and the other abnormal app takes you could see also so this child don't only have

hepatoblastoma but also have OSHA's metastases so the scan is done to evaluate the extent of the cancer the last cases study is the 41 year old

fine versed is extensively metabolized by the liver so I mentioned the Cy p450

systems so the specific enzyme that metabolizes versed cyp3a4 now that sounds like way too much information but what's important about that is there are some drugs that are also metabolized by the same enzyme that are inhibitors of

this enzyme and one of them is verapamil so at my institution when you order verapamil and versed together a warning comes up that's telling you that the verapamil may potentiate the effect of the versed and that's because the

verapamil is inhibiting the metabolism of the versed which means it's sticking around longer it's a consideration because we give wrap a mill for our radial access cases for a Vizsla spasm prophylaxis and neural patients yes yeah

a lot of neural patients for a cerebral vasospasm properties it's 97 percent protein bound so that means if you have a patient who has low serum albumin you may see a more potent effect right away because they don't have as an

a lot of protein circulating so that drug won't have protein to bind to half life in patients with renal failure reduced elimination of an act of the active metabolite can cause drug accumulation and prolonged sedation and

I'll tell you why that's especially important in the next couple of slides and then considerations prolonged tap life and the elderly obese and reduce hepatic and kidney function I think most of us know this but I think it kind of

helps to drive at home if you know why why is it prolonged half life in reduced kidney function well it's because it's 97% protein bound and it needs to be excreted by the kidney and you have an active metabolite circulating around not

getting cleared opioids are the mainstay

the ablation concept in general is to provide an environment that is

completely hostile to tumor minus 40 degrees Celsius 150 degrees Celsius 500 gray which is a radiation dose we say it's very hard for it's about anything to survive but so why is it that it doesn't always work well that's a

function of all those parameters that you see there we got to make sure we pick the right patients we got to make sure that we treat tumor where we think it is and avoid trading things that don't need treatment avoid causing

damage to collateral structures and getting a reasonable margin where we actually get some of the tumor that's microscopic there are a lot of ablation modalities radiofrequency alternates electrical current very rapidly so that

generates friction within the lesion and causes heat it looks like this a lot of times you see these little times that stick out so that you can increase the size of your blasian zone and here's a one of those deployed in a patient who

had a colorectal Curren after hepatectomy cryoablation freezes things and it pushes a gas that once it goes through a pin hole tends to expand and cause rapid freezing he can also push another gas right through it and cause

rapid heating but this is just bringing tumors to that minus 20 degree minus 40 degree threshold the nice part about cryoablation is that you can visualize your ablation zone so we're right up against the bile duct here and it tends

to be a little more respectful of tissues so that's why cryoablation is chosen every once in a while we're do frequency ablation is an excellent tool we have lots of data for it but likes it sometimes it's difficult determine where

the ablation zone is interprocedural e microwave ablation there was just a randomized study that came out that compared microwave ablation to radiofrequency ablation and the results are very similar

it was a very very experienced institution doing it but the whole point here is that a lot of these tools work pretty well there's no clear superiority on them but one thing that microwave offers it's very fast so generates

temperatures to boiling within the tumor in about five minutes and so it's certainly very fast as compared to radiofrequency and you can see boiling happening within this tumor that's been accessed eventually there that gas is

actually literally fluid that is boiling away from the tumor couple of cool ones this one's reversal expiration what we do here is we place probes throughout the lesion and we pulse it to confuse the membrane on the cell to think that

it's a it has holes in it that it cannot close and so what is happening is the contents inside the cell leave and that's pretty much consistent with not being able to survive the nice part is we can accomplish all that without

thermal ablation what do we mean that we don't go over about 40 degrees Celsius so if something is involving a bile duct or involving a critical structure like the ureter it's not actually going to damage it it just basically tells all

the the cells within there to stop stop undergoing the cellular mechanisms responsible for life it's a little more finicky to place you have to place these little parallel probes here's one we did that was directly write on the

bifurcation of the main bile ducts and you can see here afterwards is an immediate post contrast scan how that whole area is ablative it does not take up contrast and this patient never developed biliary strictures that side

blasian it's well tolerated and folks with advanced pulmonary disease there's a prospective trial that showed that

there are pulmonary function does not really change after an ablation but the important part here is a lot of these folks who are not candidates for surgical resection have bad hearts a bad coronary disease and bad lungs to where

a lot of times that's actually their biggest risk not their small little lung cancer and you can see these two lines here the this is someone who dr. du Puy studied ablation and what happens if you recur and how your survival matches that

and turns out that if you recur and in if you don't actually a lot of times this file is very similar because these folks are such high risk for mortality outside or even their cancer so patient selection is really important for this

where do we use it primary metastatic lesions essentially once we feel that someone is not a good surgical candidate and they have maintained pulmonary function they have a reasonable chance for surviving a long

time we'll convert them to being an ablation candidate here's an example of a young woman who had a metastatic colorectal met that was treated with SPRT and it continued to grow and was avid so you can see the little nodule

and then the lower lobe and we paste the placement prone and we'd Vance a cryo plugs in this case of microwave probe into it and you turn off about three to five minutes and it's usually sufficient to burn it it cavitate s-- afterwards

which is expected but if you follow it over time the lesion looks like this and you say okay fine did it even work but if you do a PET scan you'll see that there's no actually activity in there and that's usually pretty definitive for

those small lesions like that about three centimeters is the most that will treat in a lot of the most attic patients but you can certainly go a little bit larger here's her follow-up actually two years

that had no recurrence so what do you do when you have something like this so this is encasing the entire left upper lobe this patient underwent radiation therapy had a low area of residual activity we followed it and it turns out

that ended up being positive on a biopsy for additional cancer so now we're playing cleanup which is that Salvage I mentioned earlier we actually fuse the PET scan with the on table procedural CT so we know which part of all that

consolidated lung to target we place our probes and this is what looks like afterwards it's a big hole this is what happens when you microwave a blade previously radiated tissue having said that this

was a young patient who had no other options and this is the only side of disease this is probably an okay complication for that patient to undergo so if you follow up with a PET scan three months later there's no residual

activity and that patient actually never recurred at that site so what about

interesting to grapefruit if a few YP three a-four inhibitor so I always remembered from nursing school they said

don't give grapefruit but I never really knew why but that's why it's just inhibiting the enzyme that's required for metabolism flumazenil is the reversal agent for benzodiazepines your initial dose is going to be 0.2

milligrams over 15 seconds what's important to note about flumazenil other than the seizures that I mentioned before is that the half-life is shorter for flumazenil than it is for versed so you can see a recitation effect which is

why you really need to monitor them for a good period of time after you're giving it and monitor to make sure they don't become reefa dated we're all familiar with narcan it's the reversal agents for opioid medications the

initial dose is 0.4 milligrams given over 30 seconds and you can repeat every one to three minutes to a maximum of ten milligrams other medications I think are useful to mention because you do see them and I are usually given by an

anesthesiologist propofol is a great drug onset of action is less than one minute but it's a potent drug so you can see significant hypotension and respiratory depression for us in New York it's not permitted for use by non

anesthesiologists Dex Mehta Tommy Dean is another interesting drug that's sort of getting into the kind of talk in the IR world so in the 2018 guidelines that I mentioned before they address sex medicine

and they said that it could be an alternative for versed in particular cases it's a highly selective centrally acting alpha-2 agonist with eggsy oolitic sedative and some analgesic effects

you usually administer it as a bolus over 10 minutes and then you start a continuous infusion however some of the very potent bradycardia that you can see can be mitigated by eliminating the bolus infusion or the bolus

administration rather and significant considerations with this are hypotension and bradycardia does anyone use pres iudex in their ir suite oh you do okay you guys give it cool we'll talk our our anesthesiologists are

a little territorial with it however the research does show that it does have a better safety profile in certain patients so it you know yeah so that's my experience with it but our particular anesthesiologist that oversees our

sedation committee and all of our sedation practices is concerned about us using in an ir because not all the practitioners have experience administering it there's not a reversal so if the patient became bradycardic you

would have to treat their bradycardia with fluids or atropine or other medications for your particular institution yeah right it yes yes always look at your state guidelines yes so the a what the a sa says about the

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

looking for risk we find it in about 11 areas and they're in an order that

represents those that are highest in risk for lawsuits obstetrics tends to be the highest because of its dollar value so there are nurses that work and they're called Life Care planners and they use different charts and statistics

from the government and from the CDC that work on disease processes and birth errors and they come up with a dollar amount for the care of that child and that tends to be for the life that's predicted from government charts and

that's why those end up being in the millions of dollars and as we look we see that radiology is actually eighth on this list and the the driver behind this is the missed or heirs in diagnosis

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 these are a lot of slides most limited you know I'm talking I'm talking to you guys I'm talking showing you a lot of technical stuff you know and a lot of slides and I'm gonna talk mostly technical of you know how tips and dips are done kind of a step by step so even

the title it's kind of a workshop step by step of how basically you do you do tips and dips and what and and what are they so in general when you have when you have this is basically kind of out flow spleen spleen dumps blood into the

portal vein the mesentery dumps blood into the portal vein portal vein goes into liver liver does its thing and then dumps the blood into the eppadi veins to the right atrium okay for that because the liver is connected with the spleen

and the guts in series unlike any other organ basically the liver has to be a low-resistance organ because the portal circulation is low-pressure look the liver has to be a low-resistance organ with liver disease especially liver

cirrhosis you actually get increased resistance and in the liver with that disease and you get basically a backup of the blood flow in the portal circulation and increases the pressure in the portal circulation that's kind of

the genesis of or the pathogenesis of portal hypertension backing up circulation the spleen and in the guts then you get ascites and hydra thorax that's kind of think of it as weeping of fluid into the pleural space and into

the and into the perineum part of it is oncotic part of is osmotic basically think of it nutritional and pressure driven causes at the same time we all have potential portosystemic connections in other words they're there but they're

not connected or they're not opened up in plumbing they hold them bleed valves or pressure valves when the pressure is high and you know they start weeping or leaking you know in your in your basements we have the same thing

we have so many portosystemic connections there are about 55 named ones there are innumerable ones that are actually that are actually not named the common ones that we know are because of because of bleeding is esophageal

varices that's the connection usually between the left gastric vein and the azekah can be hazardous system you can also get gastric varices and that's usually connecting between a spleen and the left renal vein through a gas renal

shunts you can get also all sorts of connections even down in the internal hemorrhoids we get actually portal hypertension hemorrhoids and bleeding and so many numerous other shunts that we just don't have time to cut to cover

it to cover all these so the general to the general thought of treating all these complications of portal hypertension is to decompress the system to reduce the pressure and that's along the lines of years and decades of

surgery shunts that were placed and now tips ism largely replaced all these surgical shunts with the exception of Vancouver and Tampa okay that they still do some surgical actually a lot of surgical shunts most most other places

in North America converge to a tip to a tip shunt the the advantage of the tips of over surgical shunts is the usual what we hear is minimally invasive it you know it's a quick recovery less morbidity and mortality areason for

white tips has beaten the surgical shunts is the transplant era all these surgical shunts are actually extrahepatic so when you go for a transplants and liver hits the buckets they actually have to go and shut down

these shunts wherever they created them steena renal portal cable in the tips it goes out with a liver in the bucket so there's no complication of transplantation that's the real advantage of tips over surgical shunts

and that's why it's become very very prevalent in in in North America with a transplant error when approaching gastric varices just briefly another way is a BRT Oh which is to go basically into the left renal vein go up the shunt

and specifically screw rows the stomach and that's not the that's not this kind of subject of our of our discussion here I'm gonna talk to you

includes an interview of the patient abnormalities of major organ systems like cardiac status do they have a reduced ejection fraction do they have coronary artery disease I want to know

if they have an EF of 10% because if they become hemodynamically unstable and I want to give them fluids I'm not going to bolus a patient with a very low ejection fraction with two liters of fluid you're gonna cause

pulmonary edema and you're going to worsen the situation renal status is huge a lot of our patients are renal e impaired and that can affect the way that they clear the sedation medications that we're giving pulmonary status do

they have COPD asthma or sleep apnea sleep apnea is major in procedural sedation neurologic status do they have a history of seizures endocrine status hyper or hypo metabolism of medications can occur if they have a thyroid

disorder we want to know about adverse experiences with sedation in the past do they have a history of a difficult airway for us at NYU if they have been already been identified as a difficult airway that automatically means we're

doing the procedure with anesthesia current medications potential drug interactions is very important we'll go over that a few slides drug allergies and herbal supplements that they're taking tobacco alcohol or

substance use and frequent or repeated exposure to sedation agents is just going to increase their tolerance of the medications physical exam vital signs auscultation of heart and lungs and then their airway assessment sorry excuse me

do they have any Strider snoring or sleep apnea advanced RA they're gonna have a hard time tilting their neck back if they have cervical spine disease or they have rheumatoid arthritis chromosomal abnormalities like

trisomy 21 patients with Down syndrome can have an enlarged tongue that can impair your ability to manually ventilate them if respiratory depression wants to occur body habitus if they have significant obesity especially of the

head and neck areas and head and neck limited neck extension short neck decreased ornamental distance which is basically just looking at how far back they can tilt their head any neck mass and then again cervical spine disease or

trauma do they have a c-spine collar are they on c-spine precautions that's not a patient we're going to be able to manipulate their airway and then mouth opening we do use Mallampati and I'll review

that in a couple of slides so the AFC classification is a categorization of the patient's physiologic status that can be helpful in predicting operative risk it is recommended by the AFA that if a patient is an Asaf or that that

should prompt an evaluation by an anesthesiologist I will tell you at NYU we will still get procedural sedation to some patients who are in Asaf or but we like to identify it ahead of time because if they have significant

comorbidities that will potentially increase their likely hurt likelihood of having an adverse outcome we then have a lower threshold for activating a rapid response or a code if something was to happen if we got concerned about

something so the airway assessment is

there are advantages of this modality one there's less radiation exposure for

the patient we receive about three millisieverts of background radiation every year with one PET scan a patient can get up to eight years worth of background radiation in just one skin the only exposure of radiation a patient

gets in a pet MRI is through the isotope pet MRI has a better disease characterization especially for areas in a Patou biliary region the pelvic areas and the kidneys information and the relationship between lesions and

adjacent tissue is better delineated with the pet MRI so it's easier to see which part is cancerous and which partners normal cells there are varying opinions and research studies are being done to make a determination if pet MRI

is a better modality than pet CTS well PET CT is a lower-cost skin has increased accessibility there are more PET scanners available and more more technologists are trained for this modality PET CT is a shorter skin there

are no contraindications for affairs implants pet CTS are preferred method for imaging the lungs of thoracic nodules and bone structures however with a pet MRI it's good for soft tissue organs such as the brain the muscle

delivered the kidneys the pancreas our GYN pelvic structures such as ovaries the uterus and cervix and also the prostate there are limitations of this skin one it is a much longer skin one whole body pet MRI can last at least

about an hour there are contraindications with certain implants due to the magnetic factor of the of this test and is not preferred for imaging air-filled structures because it can give off artifacts there

are weight limitations for our machine our machine holes can hold up to about 500 pounds of weight it is this our machine as smaller bore compared to the white board MRI the MRI whiteboy is about 70 centimeters in diameter

our pet MRI machine is only 60 centimeters in diameter in this picture the difference of the 10 centimeter difference doesn't seem much however if you put a patient in there and this is one of our coworkers

he is 270 pounds and 6 feet tall and the white board MRI his shoulders fit comfortably well inside it in the sky inside the scanner however in this pet MRI machine he said he did feel a little snug and a little tight inside

but you also have to take an account that we have to put coils on top of our patients that 10 centimeters does make a big difference the coils will help us give the good quality images that we like and I also have to note that we

have to put the head coil or the helmet on top of the patient's head to give good images of the brain the reason why the pet MRI scanner is smaller is because we have to make room for the pet detectors we try to make it bigger the

gradient coil on the radiofrequency coil have to be further away from the center of the magnet and that compromises the quality of our images so which patient

positron emission tomography is the use

of a radioactive tracer in this case FD gee her fluorodeoxyglucose to assess the metabolic activity of ourselves ftg is tagged with glucose and glucose is used by our body for energy cancer cells are thought to be our Armour hypermetabolic

so if we inject FDG to our patients it goes to areas with hyper metabolic activity this area is called a hotspot and when a hotspot is noted in a PET scan its it's thought to be cancerous this is an example of a hyper metabolic

region noted in the pelvic area of the patient this patient is diagnosed of cervical cancer and what is MRI as you all know MRI is the use of radio frequency currents produced by strong magnetic fields to provide detailed

anatomical structures it is the preferred method for imaging soft tissue organs and there's no ionizing radiation present now what is pet MRI pet MRI is a combination of these two modalities instead of going to two scans using two

scanners we have one scanner that is able to obtain pet and MRI images simultaneously so why can't we just call this pet well we run through a few problems we have fdg-pet CT where it's a PET scan with low-dose CT accompanying

it and there's fdg-pet CT with diagnostic CT we're full sequences of CT is coupled with a scan and a pet MRI always has a diagnostic MRI done with 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

timing of a minute administration is that you need to know the drugs time of onset peak response and duration of action and titration of drug to effect is an important concept so you need to know whether the drug you just gave hit

its peak effect before you start Rideau seing them that concept is called Li and C to peak drug effect and all that's saying is that you just want to make sure that you're hitting the peak effect before you redose if you don't you can

have dose stacking which can put the patient at risk for toxicity and latency to peak drug effects can be changed by the physical physical chemical properties like we just discussed so how much it provides to protein is it lipid

soluble it's basically talking about how quickly it can get to the site of action and do what it needs to do pharmacokinetic and pharmacodynamic variability is basically just telling you that I could give one person a

milligram of versed and then give the next patient a mil a milligram of versed and they can have completely different responses and some things we can predict ahead of time and other things are we're just not going to know I mentioned the

cytochrome p450 system there are patients that have genetic variances of those enzymes that can change the way they metabolize the drug there's no way that we're going to know that beforehand the way that you deal with this or

tackle this problem is you start small assess and adjust we all know this you learn this in nursing school it's easy to add more it's always going to be worse to try to take it back you won't be able to take it back

I like this chart just because it kind of talks about the different variables that you may encounter so we already talked about the pharmacokinetic variabilities but some of the pharmacodynamic variabilities are going

to be your drug receptor status genetic factors drug interactions and tolerance when I look at drug receptor status I'm thinking methadone buprenorphine if you have a patient on buprenorphine and that receptor is occupied by the

buprenorphine it's going to cause competition for the next opioid you try to give like fentanyl we've had some problems patience in our department with this drug as far as titration is concerned

you want to administer each component individually to achieve the desired effect now this was a change for us when I first started talking about this because we used to give versed and fentanyl together every single time but

with the AFA recommends is that you give the drugs individually monitor the response and then assess accordingly this is an algorithm I found on up-to-date it's just a suggestion obviously it's not going to fit every

patient but it's just describing how you would start out with midazolam first give that time to hit the peak effect which again remember is gonna be 3 to 5 minutes and that can feel like a long time NIR so it's a little painful to do

this but it is going to I think lead to a better outcome for you and for the patient as far as their experience then if necessary give fentanyl I usually give that for the access because really I think for the most part most of the

things we do aren't overtly painful there may be painful parts of the procedure but it's not just two hours of pain or it shouldn't be and then you want to observe the patient if you gave fentanyl you really want to wait five

minutes and then redose from there so usually I just give the one dose of fentanyl and then I stick with my versed by eliminating that that double dose every time you're going to be able to go higher on your versed or your fentanyl

depending on what you need to give so that makes sense to everybody we were we were giving we call it one round versed in fentanyl one round and then by the fourth round nurses were understandably going oh good I the

patient needs more but I feel really uncomfortable and a CRNA said to me one day why are you guys giving fentanyl and versed every time it's great for the synergistic effect but you're going to hit that feeling a lot faster than if

you just give small incremental doses of versed to get them through the procedure and leading into synergistic interactions so giving a benzodiazepine and opioid together elicits a synergistic interaction you can think of

it as 1/2 plus 1/2 equals 4 in the city and that's a lot of what we were seeing we were seeing this you know give the fence alone verse said okay they're really sedated and then they're not anymore and then they're really

sedated and then they're not anymore versus this really nice steady maintenance of sedation during the procedure intra procedure you want to be

them so my particular area of interest is a blade of radium ization and what we'd like to do is to break the liver

down into a bunch of little tiny perfused volumes off of a single vascular pedicle or what we call angio zones and those are those allow us to segment out if you only have small volume disease for example like here in

segment three why do I have to treat the entire left to paddock low I can actually treat just that small portion just like it what it tastes only now I'm administering y9t but since it's expendable liver I

can administer doses that are way higher orders of magnitudes higher than what I could if our infusing into the liver just on its own so here's an example of that if you look at this lesion in the right of panic lobe you'll see these

little lines over them what we want to achieve is around a 205 GRA threshold for these lesions that's the red line everything that's south of red in terms of color orange Holly to blue is not cold enough to kill tumor so if we

administer a dose of a tea grade to the lobe we get this coverage which is to be a partial response if I administer 150 grey suddenly that red line gets larger what happens when you administer 400 grey now you've officially covered the

entire lesion and so you're going to lose the adjacent liver at those kind of doses and as well - what what the real question then is not sort of how much dose you give it's you give what you need to to ablate the tumor in its

entirety and you see what the patient's left with if someone's left with anatomically a lot of remnant liver because of how you've segmented out that lesion then go ahead and dose extremely high and that's essentially what we've

seen in pathologic results it's one of the highest things of high school pathological crosa rates you can achieve with a trans arterial therapy it's highly competitive with thermal ablation in the correctly selected bleezin

so this is an example of what it looks like when you segment out a little lesion like this and this patient ultimately went to resection and this was a complete pathologic necrosis but as you can see even it was a cirrhotic

patient we chose a very small volume of liver that we felt the patient would tolerate so that's a blade of vernalization let's take a look at what looks like in real time so we have a little capsular lesion we felt that

ablating this patient who was a potential transplant candidate we felt we can probably with a blade of radium realization so you go in and this is the comb beam CT that looks at a complete enhancement of the lesion within the NGO

zone this is what the MAA looks like when we administer it you can see how it tends to cluster within the tumor but you can see what the adverse territory is the liver adjacent to it this is what the engine room looks like how highly

selective it is the day of and this is what the wine ID actually looks like is the wine 90 doing its job and you can see how conformal it is there's no risk whatsoever to the liver that's adjacent outside of that field of

a maximum of around 11 millimeters and this is a patient at one month with a complete imaging response and this patient never developed a recurrent to the site and what's actually sole mode of treatment for this person's liver

cancer this is how you get complete pathologic response if you look at those little tiny grey dots in there those are actually the spheres within tiny little vessels within the tumor sometimes they go even to the portal branch but you can

see how they're not clustered uniformly but when you make them super hot that allows them to give range where otherwise they would be fine a little bit short so this also applies to the whole lobe this was a patient that had a

very unusual presentation of colon cancer that was invading the portal II we weren't sure what to do with this patient no one was because a very rare occurrence so we said well we would like

to resect him but there's not enough liver and we're not sure if this person's gonna survive because we've never seen portal cancer invading the portal vein so we said let's treat it with the radiation lobectomy and what's

cool here is if you look at the the arteries even though the tumor is invading the portal vein it's bringing arterial supply along with it like a vagabond and that's the conduit that allows us to treat these patients so

when we saw that we felt this patient we good candidate for irradiation lobectomy which is applying an ablative dose of y9t to the entire low not just a small segment in patients where otherwise cannot because of the anatomy the tumor

or if you're trying to shrink that lobe to get that person ready for surgery why because if you look at the size of the lobe on the left from this first image and compare it here you can see how much larger it got what happens is that part

that the surgeon ultimately tens on resecting in volutes over time and becomes completely vitalized and turns into scar tissue so we know that if a surgeon goes in afterwards to cut it out it's going to not result in liver

failure and that level of security allows people to have sir who otherwise wouldn't this patient is not going to have metastatic disease because we followed their blood level markers let me see how low they are and

is going to have enough liver remnant so the patient went to resection and this is the pathologic specimen and this was also a complete pathologic necrosis so I

the traditional three pillars are

surgical medical and rad honk which actually was once part of radiology and separated just like interventional radiology has and where is the role for this last column so many patients are not medically operable so if you set the

gold standard you know that the cure for someone has a primary liver mass well about 20 percent of patients who present can undergo resection what you do for the remaining portion so Salvage is what we offer when someone has undergone

standard of care and it didn't work how do we hop back in and try to see how much these folks it's low-risk it's not very expensive at all as compared to things like surgery and the recovery is usually the same date so

this concept here of tests of time is kind of interesting a lot of times when we look at a tumor let's say it's 2 centimeters it's not really the size of the tumor but it's how nasty of a player it is and it's

difficult to find out sometimes so what we do is we'll treat it using an IR technique and watch the patient and if they do well then we can subject them then to the more aggressive therapy and it's more worthwhile because we've found

that that person is going to be someone who's likely going to benefit you can use this in conjunction with other treatments and repeat therapy is well tolerated and finally obviously palliation is very important as we try

to focus on folks quality of life and again this can be done in the outpatient setting so here's a busy slide but if you just look at all the non-surgical options that you have here for liver dominant primary metastatic liver

disease everything that's highlighted in blue is considered an interventional oncology technique this is these the main document that a lot of international centers use to allocate people to treatments when they have

primary liver cancer HCC and if you see if you see at the very bottom corner there in very early-stage HCC actually ablation is a first-line therapy and they made this switch in 2016 but it's the first time that an

intervention illogic therapy was actually recommended in lieu of something like surgery why because it's lesions are very small its tolerated very well and it's the exact same reason why your dermatologists can freeze a

lesion as opposed to having to cut everything off all the time at a certain point certain tumors respond well and it's worth the decrease in morbidity so

female recently diagnosed with cervical cancer this is the baseline imaging the

one on the left is pet the one on to your right is pet MRI which one you think the doctor likes better so there is a cervical lesion you could see the abnormal uptick or hypermetabolic uptake in the cervical area that's what we call

hot spots but we do a closer look because the pet MRI this time is used or done for planning for surgery or treatment look at the actual pet MRI you could see the hypermetabolic uptake in the cervical area the normal bladder

and normal uterus those are normal updates under your right you could see the uterus full the full outline of the uterus and exactly where the cervical lesion is located and the bright one at

the bottom is the normal blood er this scan is done to help the doctors plan for the surgery and to check if there is metastasis at this time there's none and the path MRI is choice of modality of choice for this reason because MRI is

the only modality that could do all the planes and it does very good in differentiation of tissues this is the end of our presentation and if you have any questions feel free to do so I did not pass out thank you

[Applause] [Music] [Applause]

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

all about effective bag-valve-mask it's the mainstay of airway management and procedural sedation but also in the o.r so you're gonna see if you're ever working with an anesthesiologist that

the first thing they want to see is how easily they can ventilate the patient with a mask and if they have trouble they know that's potentially going to be a patient that may give them difficulty later on when they're attempting to

intubate because when they go to intubate the patient if they're not successful they immediately stop and go back to bagging the patient they want to know that that's gonna be there their failsafe and that they have an

effective way of delivering breaths the difficult airway is going to be defined in terms of whether effective gas exchange can take place with an Ambu bag so at NYU we use the sorry we use the Mallampati so this classification system

attempts to grade the degree of airway difficulty the foundation of the assessment is that the tongue is the largest anatomical structure that can inhibit mask ventilation now again if you look at the research surrounding

this Mallampati used in isolation it's not useful you really want to look at all of the other airway assessment criteria that I just previously discussed because it's on our required documentation you know it can be

something that maybe providers get focused on just open your mouth cool and move on but it really is important to look at all the other components not to call out my attending sitting over there so this is a great mnemonic that I like

moans it's just a quick easy way to identify a patient that may give you a little bit of trouble when it comes to manual ventilation so M is for mask o for OB 3a for age and for no teeth and s for stiff lungs so you can see with this

patient here with the beard he has a lot of facial hair so that's a patient that you're gonna have a difficulty getting a good seal with and if you can see they actually covered his beard with Tegaderm in order to get an effective seal right

painful later but great for his airway um last thing yes at this point oh great this points you guys can still hear me okay so for this patient for for obese patients in general my biggest pain point I guess you could say is when I

see patients inappropriately position during procedural sedation and a nurse will call and say the patient's not really well sedated but his his capnography waveform looks all off he's occasionally having periods of apnea can

you come and help and the patient looks like this so a patient who's sedated is not going to be able to comfortably spontaneously mentally win their position like that you can see his airway is a little bit compressed here

he has to overcome extra body habitus in order to effectively take a breath so what you want to do is just ramp your patient and this is obviously extreme like if you're doing an angiogram you're not the providers gonna say what on

earth are you doing but what you can do is take that pillow out and put a little roll underneath the shoulders and you're gonna see the airway open up and if I get patients who come in and they can't be flat maybe they have congestive heart

failure so they have that pillow orthopnea you can position them like this give them the sedation and then take everything out that's what I always do you you want to make sure that you have

good positioning and that's going to set you up for success patients who are elderly or have no teeth are going to be what we call a dentist and they essentially just have loss of musculature in the face which is going

to correlate with surface area which means you're not gonna be able to get a good seal so what they did in this particular patient is they actually put gauze in to just increase that surface area and then patients with stiff lungs

are going to be patients who have a history of COPD or any other restrictive lung disease and they just may be difficult to ventilate Pharmacology and

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

checking on the patient periodically at least every five minutes and monitor the

response to verbal commands if a verbal response isn't possible come up with some technique with the patient ahead of time if they're gonna give you a thumbs up or thumbs down if they're gonna close one eye raise an eyebrow whatever they

want to do come up with that come up with that with them in advance and use that to guide their to their ability to maintain their airway because sedation is going to be the main indicator of eventual respiratory depression if

that's going to occur it's not going to be your respiratory rate or your other dimo dynamics it's going to be the level of sedation we we have this problem a lot one of the nurses came up to me the other day and said the doctor told me

not to talk to the patient during the procedure I said no that's just pull this up I always say pull up the guide line this is Society event you can say this is your Society they told me I need to assess the patient every five minutes

and assess their response to me there has to be some sort of verbal response the patient doesn't have to move their arms around or give you a hug it's it's really just saying I'm okay Richmond agitation sedation scale

this is what we use at NYU this is a scale essentially to measure the level of sedation our goal is to try to get patients into this negative three sometimes it's not always possible but we want to use this to determine whether

or not the patient is slipping into a deeper level of sedation and again that's important because this is going to tell us that the patient is then at risk for respiratory depression or apnea if they transition into a negative 4 or

negative 5 ventilatory depression and airway obstruction are two different problems I just think it's important to know this because it's gonna require two different rescue mechanisms although you will usually see both of these happening

at the same time I only saw one time where it was true ventilatory depression it was in the neuro suite does anybody do wadda tests yeah okay so I had only I've only seen this once but we gave the amytal and the patient had complete

depression of their respiratory center so she did not breathe at all we had to do really deep stimulation in order to get her to take a breath so we could have done all the airway maneuvers in the world it wasn't going to help her we

had to wake her brain up and tell her to take a breath if she didn't we would have had to have intubated her that would have been the only way to rescue her because as far as I know there's no reversal for the amytal that we give bag

mask ventilation this is the cornerstone of basic airway management it's not a skill easily mastered I think a lot of people will sometimes fly through this because you do this in ACLs if you worked in an ICU you did this a hundred

times but what's different between this and a sedation setting and in a code situation is the patient and the code is already dead the thing that's not going to save them is is you're good you know Ambu bag skills it's gonna be the CPR

what's going to save your patient who is respiratory depressed in a procedural sedation setting is effective airway skills because according to the H a ventilation via an Ambu bag may be just as effective as ventilation via an

endotracheal tube that's huge so you can buy your patients some time while you're getting the reverse or you're calling for an anesthesiologist to come and intubate them if you're not able to effectively

ventilate them and they progress to a CPA as I'm sure you're all aware that just is a major indicator for eventual poor outcomes the patient could experience some airway techniques that are helpful you can do the head tilt

chin lift or a jaw thrust in patients what you do want to be mindful of obviously if they're in c-spine precautions if you are doing the procedure with procedural sedation which I would caution against then you would

just go right to a jaw thrust you're obviously not going to manipulate their cervical spine and capnography I know everyone knows capnography I'm a huge huge fan of capnography I can't stress it enough I think does everyone use it

does anyone not use it you don't use it okay okay just know if you are having trouble getting your institution to provide the finances if that's their concern as I just showed you in the beginning of the presentation there is

very strong evidence showing that there it's a positive outcome for the patient if something was to happen one day with a patient and and maybe it was to go to litigation although guidelines aren't meant to be a

hard and fast rule likely it would be brought up in the litigation they would say why do all of these organizations recommend capnography but it wasn't used in your institution and then they may say well we haven't seen any cost

benefit and then they would say well but there is cost benefit it's level a one evidence so it's really really useful and most importantly pulse-ox is going to report an average saturation overtime so you are going to see some lag so it

could be one to two minutes before you actually see a change in the pulse ox and your patient may not have been breathing for those one to two minutes so once the pulse ox does go down it's going to go down real quick and also if

you want to look at some additional resources I think the air and capnography toolkit they did not ask me to say that but I do think it is actually really really great and it was put out

steer another thing I just want to say to make the capnography work for you I think in our institution we've been using it for a long time but it doesn't always work we use this nasal cannula that's supposed to have this nice little

reservoir but it's really not great because it's cold in the room so the plastic will stiffen and it flips up use some tape or I just put a simple mask over the nasal cannula and then you'll get your waveform you'll have the the

carbon dioxide captured I think there's some fancy masks out there I think Medtronic is may be releasing a mask that does a capnography which will be great but in the meantime just make it work for you and make it work in the

beginning of the procedure sooo as you're giving more and more sedation potentially you're not then worrying about futzing around with making the capnograph you work nonpharmacologic methods I think are really important so

we get this a lot Twilight are you giving me propofol it's the same as a colonoscopy right or you're gonna knock me out right right so these are really important conversations to have in the prep area when you're getting your

patient ready make them aware they're not going to have these things and be honest with them if they're adamant they want to be asleep they want the Twilight you reschedule there it's I have found it's not worth trying to convince them

to do something that they don't want to do because they're just gonna write a really nasty letter later and and I don't and I don't blame them because I think sometimes we're not honest and we think we're doing the right thing and

you know don't worry we'll get you through it were you gonna be really comfortable and sometimes patients aren't going to be comfortable and that's okay and if they're not okay with that then we have to do what we need to

do to make sure that we're meeting what their needs and that leads into setting realistic expectations I always tell patients you might not see me the whole time I'm gonna check on you at least every five minutes if you don't see me

it's because I'm right behind you tell me what you need every five minutes I'm going to say are you okay if you need to be a little bit more asleep if you're in pain you're having anxiety tell me and I'll give you more medication this is a

collaboration and I find that that really eases a lot of the anxiety especially them knowing you're right behind them the whole time if they can't see you like their tented you know without a halo I think yeah the covered

halo we were talking about before if they can't see you it gives them a lot of anxiety if they think no one's in the room and there's just a provider they can't see doing a procedure on them sedation scripts my attending left but

we had a little bit of a healthy argument about this so I talked to him about scripting the way that we talked to patients about sedation so we're all saying the same thing all the time and he said you know I'm an attending and I

I didn't do a residency and a fellowship to be a robot and all these things and you know it was and I he loves giving me a hard time about this stuff so it was kind of funny because he's doing he's currently engaged in a grant project

that's looking at our work flow throughout the institution and he has research assistants that are working on it with him and one of the things that they did was they went on the floor with some of our residents who are consenting

the patients for procedures and she the very next day in a meeting it was totally unrelated it said to him you know they're saying the wackiest things to the patients some of them are saying don't worry about it you'll be asleep

yeah yeah it's like whatever you had last time and they're really not setting them up with realistic expectations so when we get them at least our impatience when we get them down stairs for their procedure they're totally confused about

what they're gonna have done and then I think they feel very anxious because they're about to go right into the room and now we're telling them you're not going to be asleep you'll you'll be able to talk to me during the keys so you're

not saying everyone has to be a robot and say exactly the same thing but I you may want to talk to your staff about hitting the same take-home messages so that they're not hearing all different descriptions of sedation throughout

their stay all right thank you everyone
