Case Summary | Portal Vein Thrombosis: Endovascular Management

so we kind of had a bunch of portal vein cases I think we'll stick with that theme and this is a 53 year old woman who presented to the emergency room with severe abdominal pain about three hours after she ate lunch she had a ruin why two weeks prior the medications were

really non-contributory and she had a high lactic acid so she they won her a tan on consi t scan and this is you can see back on the date which is two years ago or a year and a half ago we're still seeing her now and follow-up and there

was a suggestion that the portal vein was thrombosed even on the non con scan so we went ahead and got a duplex and actually the ER got one and confirmed that portal vein was occluded so they consulted us and we had this kind of

debate about what the next step might be and so we decided well like all these patients we'll put her on some anticoagulation and see how she does her pain improved and her lactate normalized but two days later when she tried to eat

a little bit of food she became severely symptomatic although her lactate remain normal she actually became hypotensive had severe abdominal pain and realized that she couldn't eat anything so then the question comes what do you do for

this we did get an MRA and you can see if there's extensive portal vein thrombus coming through the entire portal vein extending into the smv so what do we do here in the decision this is something that we do a good bit of

but these cases can get a little complicated we decided that would make a would make an attempt to thrombolysis with low-dose lytx the problem is she's only two weeks out of a major abdominal surgery but she did have recurrent

anorexia and significant pain we talked about trying to do this mechanically and I'd be interested to hear from our panel later but primary mechanical portal vein thrombus to me is oftentimes hard to establish really good flow based on our

prior results we felt we need some thrombolysis so we started her decided to access the portal vein trance of Pataca lee and you can see this large amount of clot we see some meds and tera collaterals later i'll show you the SMB

and and so we have a wire we have a wide get a wire in put a catheter in and here we are coming down and essentially decide to try a little bit of TPA and a moderate dose and we went this was late in the afternoon so we figured it would

just go for about ten or twelve hours and see what happened she returned to the IRS suite the following day for a lysis check and at that what we normally do in these cases is is and she likes a good bit but you can see there's still

not much intrahepatic flow and there's a lot of clots still present it's a little hard to catheterize her portal vein here we are going down in the SMB there's a stenosis there I'm not sure if that's secondary to her surgery but there's a

relatively tight stenosis there so we balloon that and then given the persistent clot burden we decide to create a tips to help her along so here we are coming transit paddock we have a little bit of open portal vein still not

great flow in the portal vein but we're able to pass a needle we have a catheter there so we can O pacify and and pass a needle in and here we are creating the tips in this particular situation we decide to create a small tips not use a

covered stent decide to use a bare metal stent and make it small with the hope that maybe it'll thrombosed in time we wouldn't have to deal with the long-term problems with having a shunt but we could restore flow and let that vein

remodel so now we're into the second day and this is you know we do this intermittently but for us this is not something most of the patients we can manage with anticoagulation so we do this tips but again the problem here is

a still significant clot in the portal vein and even with the tips we're not seeing much intrahepatic flow so we use some smart stance and we think we could do it with one we kind of miss align it so we

end up with the second one the trick Zieve taught me which is never to do it right the first time joking xiv and these are post tips and yo still not a lot of great flow in the portal vein in the smv

and really no intrahepatic flow so the question is do we leave that where do we go from here so at this point through our transit pata catheter we can pass an aspiration catheter and we can do this mechanical

aspiration of the right and left lobes you see us here vacuuming using this is with the Indigo system and we can go down the smv and do that this is a clot that we pull out after lysis that we still have still a lot of clot and now

when we do this run you see that s MV is open we're filling the right and left portal vein and we're able to open things up and and keep the the tips you see is small but it's enough I think to promote flow and with that much clot now

gone with that excellent flow we're not too worried about whether this tips goes down we coil our tract on the way out continue our own happened and then trance it kind of transfer over to anti platelets advanced or diet she does

pretty well she comes back for follow-up and the tips are still there it's open her portal vein remains widely Peyton she does have one year follow-up actually a year and a half out but here's her CT the tip shuts down the

portal vein stays widely Peyton the splenic vein widely Peyton she has a big hematoma here from our procedure unfortunately our diagnostic colleagues don't look at any of her old films and call that a tumor tell her that she

probably has a new HCC she panics unbeknownst to us even though we're following her she's in our office she ends up seeing an oncologist he says wait that doesn't seem to make sense he comes back to us this is 11 3 so

remember we did the procedure in 7 so this is five months later at the one year fault that hematoma is completely resolved and she's doing great asymptomatic so yeah the scope will effect right that's exactly right so so

in summary this is it's an interesting case a bit extreme that we often don't do these interventions but when we do I think creating the tips helps us here I think just having the tips alone wasn't going to be enough to remodel so we went

ahead and did the aspiration with it and in this case despite having a hematoma and all shams up resolved and she's a little bit of normal life now and we're still following up so thank you he's

great case and it's sort of a great book

end to what we opened with when I showed you a case of a woman with a massive P you've got some stents and there was still clot but it follow up all the rest of the clot disappears because once you create a flow channel people then life

by making their own endogenous TPA and that's essentially what you've leveraged over there enough flow that with anticoagulation she cleaned out veins that you hadn't even touched including the splenic vein so and created and what

I used to call an obsolescent tips a short-timer that you can now release her from complete follow-up from which is a really kind of elegant final closure you can leave her for her oncology follow-up for her non tumor so any closing

comments that you want to make for kind of cool collection of cases anything from the audience as we as we wrap you up we're know we're a couple minutes over time so from us this has been great fun and we're very happy that you had us

here and hopefully this was interesting for you folks as well thank you very much on behalf of all of us
