Primary constrained TIPS for treating refractory ascites or variceal bleeding secondary to hepatic cirrhosis

Objective:To report an initial experience using a primary constrained transjugular intrahepatic portosystemic shunt (TIPS) technique for treating cirrhotic patients with refractory ascites or variceal bleeding.Methods:All patients undergoing primary constrained (n = 9) and conventional (n = 18) TIPS between July 2014 and June 2016 were retrospectively reviewed. Preprocedure demographics, Child–Pugh, model for end-stage liver disease and technical variables were recorded. Outcomes measured included technical and clinical success, complications, 30-day mortality, as well as necessity for TIPS revision. Average (SD) and median follow-up was 237 (190) and 226 days.Results:All constrained and conventional TIPS were technically successful (100%). Clinical success as defined as a reduction or improvement in presenting symptoms was 88.9% (8/9) and 100% (18/18) in the constrained and conventional groups, respectively (p = 1). The average reduction in portosystemic gradient was lower in the constrained group, 6.1 m...
