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.
Background & aims: 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.
Methods: Between May 2018 and December 2021, 466 consecutive patients with recurrent variceal bleeding treated with covered TIPS were prospectively included. Post-TIPS PPG were measured immediately (immediate PPG), 24-72 hours (early PPG), and again 1 month (late PPG) after TIPS placement. The agreement among PPGs measured at different time points was assessed by intra-class correlation coefficient (ICC) and Bland-Altman method. The unadjusted and confounder-adjusted effects of PPGs on the clinical outcomes (portal hypertension complications [PHC], overt hepatic encephalopathy [OHE], further decompensation, and death) were assessed using Fine and Gray competing risk regression models.
Results: The agreement between early PPG and late PPG (ICC: 0.34) was better than that between immediate PPG and late PPG (ICC: 0.23, p<0.001). Early PPG revealed an excellent predictive value for PHC risk (early PPG ≥ vs <12 mmHg: adjusted HR [95%CI]: 2.17 [1.33-3.55], p=0.002) as well as OHE (0.40 [0.17-0.91], p=0.030) while immediate PPG did not. Late PPG showed a predictive value for PHC risk but not OHE. By targeting the lowest risk of further decompensation, we identified an optimal hemodynamic target with early PPG ranging 11 to 14 mmHg that was associated with a decreased risk of OHE while effectively preventing PHC.
Conclusions: PPG measured 24 to 72 hours after TIPS correlates with long term PPG and clinical outcomes, and hemodynamic target with a PPG 11-14 mmHg reduced encephalopathy but not compromised clinical efficacy.
Impact and implications: The optimal timing of measurement and hemodynamic targets of portacaval pressure gradient (PPG) after transjugular intrahepatic portosystemic shunt (TIPS) remains inconclusive. Here we show that post-TIPS PPG measured at least 24 hours but not immediately after the procedure correlated with long-term PPG and clinical events, therefore should be used for decision making in order to improve clinical outcomes. Targeting post-TIPS PPG at 11-14 mmHg or 20%-50% relative reduction from pre-TIPS baseline that measured 24-72 hours after procedure reduced encephalopathy but not compromised clinical efficacy, therefore could be used to guide TIPS creation and revision in patients with cirrhosis and variceal bleeding undergoing covered TIPS.
