Clinical study on transjugular intrahepatic portosystemic shunt creation with 8 mm diameter covered stent-graft / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical results of transjugular intrahepatic portosystemic shunt(TIPS)creation with 8 mm diameter covered stent-graft. Methods Ninteen concecutive patients with portal hypertension underwent TIPS creation with 8 mm diameter covered stent-graft for variceal bleeding and/or refractory ascites. Evaluation of the results through observing the improvement of clinical symptom and periodic follow up was carried out. Results Technical success achieved in all patients reaching 100% without related complications. Median follow-up was 13.5 months(ranged, 2.7 - 28 months). One case(1/19,5.3%)showed aggravation of hepatoencephalopathy and 2 others(2/19, 10.5%)revealed rebleeding. The primary patency rate was 100%(16/16)after 6 months, and 87.5%(7/8)after 12 months. Improvement or resolved rate of ascites was 66.7% (12/18). Conclusion TIPS creation with 8 mm diameter covered stent-graft can degrade the incidence of hepatic encephalopathy, improve the rate of TIPS patency and keeping the effective shunt flow.
