This study concludes that the presence of TIPS has a protective value against the development of post-BRTO ascites/hydrothorax as well as recurrent hemorrhage but this does not translate to improved patient survival.
Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.
The management of parastomal varices is not established. Transjugular intrahepatic portosystemic shunt (TIPS) creation is the most commonly described treatment; however, the rebleed rate after TIPS is 21-37%. The purpose of the study is to determine the effectiveness of transvenous obliteration using sodium tetradecyl sulfate (STS) and to describe a new simplified technique in obliterating these varices. Four patients are presented who underwent transvenous obliteration using STS. One was obliterated using balloon occlusion from the systemic veins, the second was obliterated without balloon from a transhepatic antegrade approach, and the last two patients were obliterated using the direct antegrade technique. This simplified technique requires only a micropuncture kit (not requiring balloons or coils) and ultrasound transducer compression of the systemic draining veins, relying on high portal pressure to keep the sclerosant confined to the varices. The sclerosant is essentially trapped between the portal pressure and the ultrasound-transducer compression (10-15 min). Technical success was achieved in all four patients without procedural or postprocedural complications and no rebleeding for a mean follow-up of 17 (range 2-33) months. Transvenous obliteration of parastomal varices utilizing STS as a sclerosant is safe and effective. The newly described technique is simple, feasible, and requires minimal equipment (no balloons or coils or catheters).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
