Large Paraumbilical Vein Shunts Increase the Risk of Overt Hepatic Encephalopathy after Transjugular Intrahepatic Portosystemic Shunt Placement.

ABSTRACT:

Background

This study aimed to evaluate whether a large paraumbilical vein (L-PUV) was independently associated with the occurrence of overt hepatic encephalopathy (OHE) after the implantation of a transjugular intrahepatic portosystemic shunt (TIPS).

Methods

This bi-center retrospective study included patients with cirrhotic variceal bleeding treated with a TIPS between December 2015 and June 2021. An L-PUV was defined in line with the following criteria: cross-sectional areas > 83 square millimeters, diameter ≥ 8 mm, or greater than half of the diameter of the main portal vein. The primary outcome was the 2-year OHE rate, and secondary outcomes included the 2-year mortality, all-cause rebleeding rate, and shunt dysfunction rate.

Results
