Abstract
To compare retrospectively the clinical outcomes in patients treated with transjugular intrahepatic portosystemic shunt (TIPS) using the novel polytetrafluoroethylene-covered stents (Fluency) and bare stents. Sixty consecutive patients with portal hypertension treated with TIPS from April 2007 to April 2009 were included. TIPS creation was performed with Fluency stent grafts in 30 patients (group A) and with bare stents in 30 patients (group B). Liver function, TIPS patency and clinical outcomes were evaluated every 3 months after procedures. During hospitalization, there were no cases of hepatic encephalopathy (HE) and recurrence of variceal bleedings. Acute shunt occlusion was found in one patient in each group. Follow-ups were performed in group A with average time of 6.16 +/- 3.89 months and in group B with 8.34 +/- 4.42 months. The rates of recurrent bleeding, shunt occlusion, HE and mortality were 0.03, 0.0, 16.7 and 0% in group A, and 20.0, 30.0, 20.0 and 13.3% in group B, respectively. There was no difference of HE between group A and group B. The decrease of portal pressure and portosystemic pressure gradient, and the increase of portal flow were 34.1 and 23.3%, 60.0 and 52.8%, and 189.5 and 111.1% in group A and B, respectively. There were no differences of liver function between group A and B. The Fluency stent graft is relatively safe and effective in TIPS creation, with a high patency rate compared with bare stents.
