In clinical practice, the reduction of porto-caval pressure gradient (PCPG) following trans-jugular intra-hepatic porto-systemic shunt (TIPS) does not always meet the recommendation of current guidance. We evaluated the impact of different degrees of PCPG reduction, measured at the end of an elective TIPS, on ascites control, recurrence of portal hypertension-related bleeding (PHRB) and survival.
Approach and Results:
Cirrhotic patients receiving TIPS for refractory ascites (RA) or for the secondary prophylaxis of PHRB were consecutively enrolled. Reduction in PCPG was defined inadequate (IHR) in patients not achieving a PCPG <12 mm Hg for both secondary prophylaxis of PHRB and RA, or a reduction of at least 50% only for PHRB. Four-hundred-fifteen patients were analyzed. An adequate hemodynamic response (AHR) was achieved in 66%. Fifty percent of patients received an under-dilated (≤7 mm) endoprosthesis. No significant differences between patients with IHR and AHR were observed in rebleeding rate and ascites control, while overt hepatic encephalopathy was higher in AHR. Regardless of TIPS indication, survival was not significantly different between IHR and AHR, while advanced age and liver function before TIPS were significantly associated with a higher cumulative incidence of liver-related death. Notably, the cumulative incidence of liver-related mortality was higher in RA patients when AHR was defined as a post-TIPS PCPG <12 mm Hg or a reduction ≥50%.
Conclusions:
AHR measured at the end of an elective TIPS may not be essential to define the eventual outcome, while a marked drop in PCPG could negatively affect the prognosis of patients with RA.
