Identifying the optimal measurement timing and hemodynamic targets of portal pressure gradient after TIPS in patients with cirrhosis and variceal bleeding: a prospective cohort study

The optimal timing of measurement and hemodynamic targets of portacaval pressure gradient (PPG) after TIPS remains inconclusive. This study aimed to identify the ideal moment of hemodynamic measurements and the optimal target of PPG in patients undergoing covered TIPS for variceal bleeding.
