Clinical Results of the Transjugular Intrahepatic Portosystemic Shunt

ABSTRACT

PURPOSE: To evaluate the cilinical results of transjugular intrahepatic portosystemicshunt(TIPS) for the control of variceal bleeding. MATERIALS AND METHODS: TIPS creation was attempted in 23 patients with endoscopically confirmed variceal bleeding. Most patients had multiple episodes of bleeding in the past and have been treated with multiple endoscopic sclerotherapies. Pre- and post-procedural hepatic and portal vein pressures were measured. After creation of TIPS patients were followed up at regular intervals. RESULTS: TIPS has been successfully accomplished in 22 of 23 patients using Wallstent(n=21 ) and Strecker stent(n=1 ). Immediate bleeding control was achieved in all patients with shunt creation. No procedure-related complication was noted. Portal vein pressure was reduced from 30.7+/-5.8 mmHg to 20.8+/-4.7 mmHg. The mean pressure gradient of portosystemic shunt dropped from 22.8+/-6.0 prior to TIPS to 12.2+/-4.1 immediately after. During the follow-up period (6-556 days, mean; 10months), seven patients died; progressive hepatic failure (n=4), variceal rebleeding(n=2), and respiratory failure(n=1). Hepatic encepha-Iopathy after TIPS was noted in 7 patients(31.8%). Variceal rebleeding occurred in 3 patients(13.6%). The remaining 15 patients have survived an average of 11 months. CONCLUSION: This results suggest that TIPS is a safe and effective method for lowering portal pressure and controlling variceal bleeding. Furthermore if these initial results are encourged by further long-term observation, TIPS could replace endoscopic and risky surgical intervention.
