A modified procedure for transjugular intrahepatic portosystemic shunt flow reduction.

The authors present a modified transjugular intrahepatic portosystemic shunt (TIPS) flow reduction procedure to treat TIPS-related refractory hepatic encephalopathy, giving the results and follow-up on six patients. A 6-mm-diameter Uni Wallstent was introduced over a guide wire and deployed beyond the angulated portion of the TIPS. A Wallgraft was then introduced over the same guide wire, pushed through the Uni Wallstent coaxially, and deployed in the TIPS. All cases were technically and clinically successful. There were no deaths in the first month after the procedure. In this study, three patients had more than 1 year's patency.
