- W3008615968 abstract "To determine the effect of transjugular intrahepatic portosystemic shunt (TIPS) VIATORR endograft outflow position on shunt patency. A retrospective review of consecutive patients undergoing TIPS placement and revision with VIATORR stent-grafts (Gore) from November 2014 to February 2019 was performed. Patient demographics, imaging studies and follow-up clinic notes were reviewed. The angiographic images upon TIPS creation were reviewed to assess outflow shunt location in the hepatocaval junction or right atrium (HCJ/RA) or more peripherally in the hepatic veins (HV). The HCJ was defined as a shunt outflow within 1 cm of the junction between the hepatic veins and inferior vena cava. The groups were compared using a Shapiro-Wilk test. A total of 523 patients underwent TIPS placement and 14% underwent revisions, (n = 72) with 66% (n = 47) undergoing TIPS expansion. Median age was 61 years (range, 20-76). The top 3 indications for revision were shunt occlusion (n = 23), stenosis (n = 24) and worsening hepatic encephalopathy (n = 24). Overall primary unassisted patency rates at 9, 12, and 36 months were 95%, 90%, and 88%, respectively. The mean patency of thrombosed VIATORR stent-grafts in the HCJ/RA was 800 days and 439 days in the HV (P = 0.04). Occluded TIPS locations were: HCJ/RA (35%, n = 8) and HV (65%, n = 15) (P = 0.03). Initial TIPS endograft venous outflow position can predict shunt patency, with those in the HCJ having a longer patency compared to those in the HV. This correlates to previous data regarding outflow position in TIPS created with WALLSTENT endoprostheses." @default.
