Abstract
To retrospectively analyse long-term patency and overall survival of cirrhotic patients treated with TIPSS using e-PTFE-covered stents. Additionally, prognostic factors for better patency and survival were analysed. Two hundred and eighty-five consecutive cirrhotic patients with severe portal hypertension-related symptoms were included. Follow-up, including clinical assessment and duplex ultrasound, was analysed up to end of study, patient's death, liver transplantation or TIPSS-reduction. Patency rates and overall survival were estimated by the Kaplan-Meier method; potential differences in outcome between subgroups were calculated using the Pepe and Mori test. The 1-, 2- and 5-year primary patencies were 91.5%, 89.2% and 86.2%, respectively, with no new shunt dysfunctions after 5years' follow-up. TIPSS revision was performed more often in ascites patients (P = 0.02). The 1-, 4- and 10-year survival rates were 69.2%, 52.1% and 30.7%, respectively. Survival was higher in Child-Pugh class A-B (P = 0.04), in the recurrent bleeding group (P = 0.008) and in patients with underlying alcoholic cirrhosis (P = 0.01). Long term, primary patency of e-PTFE-covered TIPSS stents remains very high (>80%); shunt revision was required more frequently in ascites patients. Overall survival was better in Child-Pugh A-B patients with recurrent variceal bleeding and alcoholic liver cirrhosis. • Long-term primary patency rate of e-PTFE-covered TIPSS stents remains very high. • No new shunt dysfunction was found after 5years of follow-up. • Shunt revision was required more frequently in ascites patients. • Four and 10years' overall survival was 50 and 30%, respectively.
