Clinical Efficacy and Survival Prediction Analysis of Transjugular Intrahepatic Portosystemic Shunt in Patients With Liver Cirrhosis

This study aims to develop a practical tool for identifying cirrhotic patients at high risk of hepatic encephalopathy following transjugular intrahepatic portosystemic shunt (TIPS) placement. A retrospective analysis will be conducted on medical records of 624 cirrhotic patients who underwent TIPS from 2011 to 2021. Statistical methods will be applied to screen preoperative routine indicators associated with post-TIPS hepatic encephalopathy risk. A predictive nomogram will be constructed incorporating the screened indicators to estimate individual preoperative risk. The predictive performance will be compared with conventional clinical scoring systems. This tool is intended to facilitate preoperative risk evaluation and targeted management of high-risk patients undergoing TIPS
