Objective:
To investigate the safety, efficacy and long-term patency of parallel shunts (PS) in the management of the transjugular intrahepatic portosystemic shunt (TIPS) dysfunction.
Materials And Methods:
Between March 2007 and October 2010, 18 patients (13 men and 5 women) who underwent TIPS revision with the creation of PS were evaluated retrospectively. In the first 10 patients, a 10-mm-diameter Wallgraft endoprosthesis was deployed; in the latter 8 patients, an 8-mm-diameter Fluency endoprosthesis was deployed.
Results:
The creation of PS was technically successful in all patients. The mean ± standard deviation portosystemic pressure gradient before and after the procedure was 25.5 ± 7.3 mm Hg (range, 16-37 mm Hg) and 10.9 ± 2.3 mm Hg (range, 7-16 mm Hg), respectively. The duration of follow-up was 16.7 ± 10.8 months (range, 6-42 months). The primary shunt patency rates at 12 months after the creation of PS was 70% with Wallgraft endoprostheses and 87.5% with Fluency endoprostheses.
Conclusion:
TIPS revision with the creation of PS is a safe, effective and durable method for treating shunt dysfunction.
