PurposeTo analyse technical and clinical success of transjugular intrahepatic portosystemic shunt (TIPS) in patients with portal hypertension and compare a stent and a stentgraft with regard to clinical and technical outcome and associated costs.Materials and Methods170 patients (56 ± 12 years, 32.9 % females) treated with TIPS due to portal hypertension were reviewed. 80 patients received a stent (group 1) and 83 a stentgraft (group 2), and seven interventions were unsuccessful. Technical data, periprocedural imaging, follow-up ultrasound and clinical data were analysed with focus on technical success, patency, clinical outcome and group differences. Cost analysis was performed.ResultsPortal hypertension was mainly caused by ethyltoxic liver cirrhosis with ascites as dominant symptom (80 %). Technical success was 93.5 % with mean portosystemic gradient decrease from 16.1 ± 4.8 to 5.1 ± 2.1 mmHg. No significant differences in technical success and portosystemic gradient decrease between the groups were observed. Kaplan–Meier analysis yielded significant differences in primary patency after 14 days, 6 months and 2 years in favour of the stentgraft. Both groups showed good clinical results without significant difference in 1-year survival and hepatic encephalopathy rate. Costs to establish TIPS and to manage 2-year follow-up with constant patency and clinical success were 8876 € (group 1) and 9394 € (group 2).ConclusionTIPS is a safe and effective procedure to manage portal hypertension. Stent and stentgraft enabled good technical and clinical results with a low complication rate. Primary patency rates are clearly in favour of the stentgraft, whereas the stent was more cost effective with similar clinical results in both groups.
