Comparison study of Doppler ultrasound surveillance of expanded polytetrafluoroethylene‐covered stent versus bare stent in transjugular intrahepatic portosystemic shunt

Abstract

ePTFE-covered stents resulted in higher patency rates and better hemodynamics than bare stents. Routine US surveillance may not be necessary in patients with ePTFE-covered TIPS stent.

Persistence of gastric or esophageal varices on final angiography increases transjugular intrahepatic portosystemic shunt revision rate after polytetrafluoroethylene-covered stent shunt creation

“…Late TIPS stenoses, which may lead to occlusion, are mostly caused by intimal hyperplasia (34,35). The use of graft stents seems to be associated with lower intimal hyperplasia (36,37). The combination of those two factors probably explains why position of the vein end graft stent and then the distance between stent and inferior vena cava had no influence on the shunt patency in our study as in the study by Andring et al (23).…”

Doppler ultrasound surveillance of TIPS-patency in the era of covered stents – retrospective analysis of a large single-center cohort

“…All DU examinations were performed with high-end ultrasound devices (Siemens Acuson Sequoia 512, Siemens Acuson S3000, Philips iU22). Our standardized protocol included analysis of flow profiles and peak flow velocities inside TIPS (portal end, middle portion, and caval end), main portal vein, intrahepatic portal vein branches, and hepatic veins [5,9,10,25,26]. Liver parenchyma was screened for hepatocellular carcinoma (HCC).…”

ePTFE‐TIPS vs repetitive LVP plus albumin for the treatment of refractory ascites in patients with cirrhosis

“…Self‐expandable polytetrafluoroethylene (ePTFE)‐covered stent grafts have been implemented into clinical routine for the treatment of refractory variceal bleeding and as early TIPS in selected patients with acute variceal bleeding related to portal hypertension. ePTFE‐covered TIPS seem to be superior to previously used, uncoated metal stents with regard to patency and stent dysfunction . Although TIPS using bare stents showed good results for controlling refractory ascites in previous trials, data on the effectiveness of ePTFE‐covered TIPS was scarce …”

“…ePTFE-covered TIPS seem to be superior to previously used, uncoated metal stents with regard to patency and stent dysfunction. 19,22,25,26 Although TIPS using bare stents showed good results for controlling refractory ascites in previous trials, [27][28][29][30] data on the effectiveness of ePTFE-covered TIPS was scarce. 31,32 Recently, Bureau et al 33 published a prospective randomized controlled trial comparing ePTFE-TIPS vs LVP+A in 62 patients with severe and/or recurrent ascites, and found increased transplant-free survival (TFS) in the TIPS group while the risk of developing HE was similar.…”
