Clinical Outcome Using the Fluency Stent Graft for Transjugular Intrahepatic Portosystemic Shunt in Patients with Portal Hypertension

Abstract

The objective of this study was to evaluate the clinical outcomes using the Fluency stent graft for transjugular intrahepatic portosystemic shunt (TIPS) in patients with portal hypertension. From January 2008 to December 2011, 150 patients (110 male and 40 female with a mean age of 51 years) with portal hypertension underwent TIPS creation with the Fluency stent graft. Indications for TIPS treatment were variceal bleeding in 134 cases and refractory ascites in 16 cases. The clinical results pre- and postprocedure were evaluated. All 150 patients underwent a successful TIPS procedure without any technical complications. The portal pressure decreased from 24.3 ± 3.2 mmHg preoperatively to 15.1 ± 2.7 mmHg postoperatively ( P < 0.001), and the portal flow velocity increased from 18.3 ± 4.6 cm/s to 55.6 ± 15.8 cm/s ( P < 0.001). Emergency TIPS was performed in 18 patients with uncontrolled variceal bleeding. During hospitalization, the rates of shunt occlusion, hepatic encephalopathy, variceal rebleeding, and death were 1.3, 0.0, 1.3, and 2.0 per cent, respectively. At a mean follow-up of 24.1 ± 8.8 months, the rates of shunt occlusion, hepatic encephalopathy, variceal rebleeding, and death were 10.0, 15.3, 11.3, and 10.0 per cent, respectively. The main causes of death were hepatic failure, hepatic carcinoma, and recurrent variceal bleeding. The Fluency stent graft is effective in TIPS creation with high patency rates and improves the results of TIPS for portal hypertension.
