Purpose: The purpose of this study is to compare shunt patency and clinical outcomes between bare stents and expanded polytetrafluoroethylene (ePTFE) covered stents in patients who had undergone transjugular intrahepatic portosystemic shunt (TIPS) creation. Materials and Methods: 43 consecutive patients with active gastroesophageal variceal bleeding who had undergone de novo TIPS creation were included in this study. For TIPS creation, bare stents were placed in twenty patients (Group 1) from January 2001 to December 2003, while ePTFE-covered stents were placed in twenty-three patients (Group 2) from January 2004 to December 2007. The primary and secondary patency rates of TIPS along with the clinical outcome were assessed, and a comparison was made between the two groups. Results: The technical success rate was 100%. Cumulative primary shunt patency rate in Group 1 was 78.5%, 55.8%, and 45.8% at 6, 12, and 24 months, respectively, and in Group 2, 91.1%, 86.0%, and 79.9%, respectively (p = 0.009). Cumulative secondary shunt patency rate in Group 1 was 86.3%, 70.7%, and 64.3%, respectively, and in Group 2, 91.1%, 91.1%, and 85.0%, respectively (p = 0.022). Conclusion: The use of ePTFE-covered stents particularly designed to spare the juxtacaval segment of the hepatic vein resulted in an improved patency of shunts compared to using bare stents.
