Introduction:
Portal vein thrombosis (PVT) and portal vein stenosis (PVS) are rare complications after liver transplantation that can lead to graft failure and patient death.
Material And Methods:
The aim of this study was to evaluate the effect of interventional treatment for PVT and PVS occlusion after liver transplantation. Follow-up data of 7 patients who underwent stent replacement for PVT and/or PVS were analyzed. The clinical success, complications, and portal vein patency were analyzed.
Results:
Clinical success was obtained in 6 of the 7 patients. No portal hypertension-related symptoms reoccurred in the 6 patients during the follow-up.
Conclusions:
Interventional radiologic treatment produced a high success rate and a favorable long-term outcome.
