Prognostic Factors for Post-Transjugular Intrahepatic Portosystemic Shunt Creation Liver Failure and Death.

Area of Science:

• Hepatology
• Interventional Radiology
• Clinical Outcomes Research

Background:

• Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure to manage portal hypertension.
• Post-TIPS liver failure (PTLF) is a significant complication impacting patient morbidity and mortality.
• A robust classification system is needed to grade PTLF severity.

Purpose of the Study:

• To assess the incidence and grading of PTLF in patients undergoing TIPS.
• To identify prognostic factors for PTLF development and severity.
• To evaluate the predictive value of the Model for End-stage Liver Disease (MELD) score for PTLF.

Main Methods:

• Single-center retrospective study including 559 patients who underwent TIPS between 1998 and 2025.
• Utilized a classification system to grade PTLF, characterizing hepatic insufficiency.
• Statistical analysis, including Area Under the Receiver Operating Characteristic Curve (AUROC), was performed to assess MELD score as a predictor.

Main Results:

• The overall incidence of PTLF was 17%, with a 6% incidence of grade 3 PTLF (death).
• The MELD score was a significant predictor for PTLF (AUROC = 0.637 for grades 1-3; AUROC = 0.785 for grade 3).
• A MELD score exceeding 16 was identified as a cutoff indicating increased risk for PTLF.

Conclusions:

• PTLF is a considerable risk following TIPS procedures.
• The MELD score is a valuable tool for predicting PTLF, particularly severe outcomes.
• Pre-procedural MELD score assessment can aid in risk stratification for patients undergoing TIPS.
