PURPOSE: To evaluate the effects of secondary deployment of expanded polytetrafluoroethylene (ePTFE)-covered stent grafts in the treatment of dysfunctional transjugular intrahepatic portosystemic shunts (TIPSs) in comparison with other common approaches (conventional angioplasty or implantation of bare metal stents).
MATERIALS AND METHODS: A retrospective review of 121 dysfunctional bare metal TIPS presenting between 2000 and 2004 was conducted. The group was divided into four subgroups according to the type of intervention: conventional angioplasty (52 cases; 43%), bare metal stent deployment (35 cases; 28.9%), nondedicated ePTFE-covered stent-graft deployment (15 cases; 12.4%), and dedicated ePTFE-covered stent-graft deployment (19 cases; 15.7%). In all four groups, the primary patency after the specific intervention was calculated and mutually compared.
RESULTS: Primary patency rates after 12 and 24 months were 49.7% and 25.3%, respectively, in conventional angioplasty; 74.9% and 64.9%, respectively, with bare metal stents; 75.2% and 64.5%, respectively, with nondedicated ePTFE-covered stent grafts; and 88.1% and 80.8%, respectively, with dedicated ePTFE-covered stent grafts.
CONCLUSIONS: In the treatment of dysfunctional TIPS, better patency after the intervention was obtained by deploying dedicated ePTFE-covered stent grafts in comparison with conventional angioplasty, bare metal stents, and nondedicated ePTFE-covered stents.
