Smaller Diameter and Adjustable Diameter Transjugular Intrahepatic Portosystemic Shunts

Abstract

Complications of overshunting, including hepatic encephalopathy and hepatic insufficiency, remain prevalent following transjugular intrahepatic portosystemic shunt (TIPS) creation. Smaller diameter TIPS may reduce the risk of overshunting, but the use of smaller stents must be weighed against the risk of undershunting and persistent or recurrent hemorrhage, ascites, and other complications of portal hypertension. This article explores the question of optimal shunt diameter by examining outcomes for smaller diameter TIPS stent-grafts (<10 mm), underdilated stent-grafts, and variable diameter stent-grafts.
