Safety and Efficacy of Overdilation of 10 mm Viatorr Transjugular Intrahepatic Portosystemic Shunt Stents Using 12 mm Balloons

Abstract

Objective The aim of this study was to evaluate overdilation of 10-mm standard and 8–10 mm controlled-expansion Viatorr stents to 12 mm during transjugular intrahepatic portosystemic shunt (TIPS) placement when insufficient reduction (<50%) in portosystemic gradient (PSG) is achieved with standard 10 mm dilation.
