title: Percutaneous intravascular stents for treatment of portal venous stenosis after liver transplantation: midterm results.
abstract: Portal vein stenosis after liver transplantation is a relatively uncommon vascular complication that may result in graft loss if not promptly treated. The purpose of this study was to evaluate the midterm result of the use of intravascular stents for portal vein stenosis after liver transplantation. From April 2004 to September 2005, percutaneous transhepatic balloon dilation with stent deployment was performed in nine cases. Varices were embolized with stainless steel coils in two cases. No procedure-related complication occurred. Portal venous patency was maintained in all nine patients from 6 to 19 months (mean 10 months). In conclusion, an intravascular stent is an effective treatment for the portal vein stenosis after liver transplantation with excellent midterm patency.
