Background: Treatment options for patients with cavernous transformation of portal vein (CTPV) are limited. This study aimed to evaluate the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) to prevent recurrent esophageal variceal bleeding in patients with CTPV.
Methods: We retrospectively analyzed 67 consecutive patients undergone TIPS from January 2011 to December 2016. All patients were diagnosed with CTPV. The indication for TIPS was a previous episode of variceal bleeding. The data on recurrent bleeding, stent patency, hepatic encephalopathy and survival were retrieved and analyzed.
Results: TIPS procedure was successfully performed in 56 out of 67 (83.6%) patients with CTPV. TIPS was performed via a transjugular approach alone (n = 15), a combined transjugular/transhepatic approach (n = 33) and a combined transjugular/transsplenic approach (n = 8). Mean portosystemic pressure gradient (PSG) decreased from 28.09 ± 7.28 mmHg to 17.53 ± 6.12 mmHg after TIPS (P < 0.01). The probability of the remaining free recurrent variceal bleeding was 87.0%. The probability of TIPS patency reached 81.5%. Hepatic encephalopathy occurrence was 27.8%, and survival rate was 88.9% until the end of follow-up. Four out of 11 patients who failed TIPS died, and 4 had recurrent bleeding.
Conclusions: TIPS should be considered a safe and feasible alternative therapy to prevent recurrent esophageal variceal bleeding in patients with CTPV, and to achieve clinical improvement.
