Technical and clinical outcome of transjugular intrahepatic portosystemic stent shunt: bare metal stents (BMS) versus viatorr stent-grafts (VSG)
Purpose: To compare retrospectively angiographical and clinical results in patients undergoing transjugular intrahepatic portosystemic stent-shunt (TIPS) using BMS or VSG. Materials and methods: From February 2001 to January 2010, 245 patients underwent TIPS. From those, 174 patients matched the inc...

| Summary: | Purpose: To compare retrospectively angiographical and clinical results in patients undergoing transjugular intrahepatic portosystemic stent-shunt (TIPS) using BMS or VSG. Materials and methods: From February 2001 to January 2010, 245 patients underwent TIPS. From those, 174 patients matched the inclusion criteria with elective procedures and institutional follow-up. Group (I) consisted of 116 patients (mean age, 57.0±11.1 years) with BMS. Group (II) consisted of 58 patients with VSG (mean age, 53.5±16.1 years). Angiographic and clinical controls were scheduled at 3, 6 and 12 months, followed by clinical controls every 6 months. Primary study goals included hemodynamic success, shunt patency as well as time to and number of revisions. Secondary study goals included clinical success. Results: Hemodynamic success was 92.2% in I and 91.4% in II (n.s.). Primary patency was significantly higher in II compared to I (53.8% after 440.4±474.5 days versus 45.8% after 340.1±413.8 days; p<0.05). The first TIPS revision was performed significantly later in II compared to I (288.3±334.7 days versus 180.1±307.0 days; p<0.05). In the first angiographic control, a portosystemic pressure gradient ≥15mmHg was present in 73.9% in I and in 39.4% in II (p<0.05). Clinical success was 73.7-86.2% after 466.3±670.1 days in I and 85.7-90.5% after 617.5±642.7 days in II (n.s.). Hepatic encephalopathy was 37.5% in I and 36.5% in II (n.s.). Conclusion: VSG increased primary shunt patency as well as decreased time to and number of TIPS revisions. There was a trend of higher clinical success in VSG without increased hepatic encephalopathy. |
