BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement in survival in patients with recurrent and refractory ascites and variceal haemorrhage. Prediction of post-TIPS survival is primarily determined by factors identified before the TIPS procedure, as data collected during or after TIPS implantation are limited. The aim of the study was to evaluate the influence of early hemodynamic changes after TIPS placement on survival, in order to refine post TIPS management.
METHODS: In this prospective bicentric study, consecutive patients (n = 105) undergoing TIPS placement for ascites or variceal haemorrhage underwent measurement of portal pressure gradient (PPG) immediately at TIPS insertion (PPG0) and 24 h later (PPG24h) and the ΔPPG was calculated from PPG24h and PPG0 (ΔPPG = PPG24h-PPG0). Kaplan-Meier survival analysis and uni- and multivariable regression analyses were conducted to identify survival predictors.
RESULTS: Patients with lack of increased ΔPPG exhibited poorer 90-day and 1-year survival compared to patients with increased ΔPPG. This worse survival was independent of The Model for End-Stage Liver Disease (MELD) score, Child-Pugh score, bilirubin levels, creatinine and the Freiburg index of post-TIPS survival (FIPS) > 0.92. Among these patients with poorer outcome, elevated bilirubin (> 25 μmol/L) further distinguished survivors from non-survivors.
CONCLUSION: Lack of increased ΔPPG post-TIPS insertion identifies a high-risk patient group with worse survival. We propose incorporating this second PPG measurement and determining ΔPPG into clinical practice to identify these patients early and tailor post-TIPS patient care.
