Abstract

PURPOSE: To compare functional and anatomic outcomes of transjugular intrahepatic portosystemic shunts (TIPSs) created with the specialized Viatorr stent versus a Wallstent/Fluency stent combination. MATERIALS AND METHODS: Retrospective review of patients who underwent TIPS creation with stent-grafts was conducted over a 54-month period ending in June 2008. Patients were divided into three groups: Viatorr only, Fluency only, and combined Viatorr/Fluency, the latter of which was included in the overall evaluation but excluded from the comparative analysis between the Viatorr and Fluency groups. Patient demographics, Child-Pugh scores, and portosystemic gradient (PSG) reduction were compared. Patencies were calculated using the Kaplan-Meier method and compared. RESULTS: A total of 126 TIPSs created with stent-grafts were found: 28 with Fluency stents, 93 with Viatorr devices, and five combined. No significance in demographic factors or PSGs was found among groups (P > .05). Major encephalopathy rates were 3.6% and 4.3% in the Fluency and Viatorr groups, respectively (P = 1.000). Hemodynamic success rates were 93% and 98% in the Fluency and Viatorr groups, respectively (P = .099). The primary unassisted patency rates at 6, 9, and 12 months were 87%, 81%, and 81%, respectively, in the Fluency group and 95%, 93%, and 89%, respectively, in the Viatorr group (P = .03). Portal and hepatic end stenoses were the causes of TIPS narrowing in the Fluency and Viatorr groups, respectively. CONCLUSIONS: The Wallstent/Fluency stent combination is associated with a 1-year patency rate greater than 80%, with no significant difference versus the Viatorr stent regarding technical and hemodynamic success and encephalopathy rate. However, the Viatorr stent is associated with improved patency (89%) versus this bare stent/stent-graft combination.
