Interventional therapy of complications after liver transplantation:arterial steal syndrome / 介入放射学杂志

ABSTRACT

Arterial steal syndrome(ASS),a scarce complication after liver transplantation,is charac-terized by hepatic arterial hypoperfusion of the graft caused by a shifting of blood flow into the splenic,left gastric,or gastroduodenal arteries. It can lead to stricture formation of biliary system and transplanted liver function exhaustion. The early diagnosis and treatment are important for protecting the transplanted liver function. Dynamic CDFI after liver transplantation as a routine is necessary to find out the suspected lesions,and transcatheter angiography as the gold standardization can give clear dignosis. Embolization of splenic artery is minimally invasive,successful and less complication treatment for ASS and especially the coil embolization of middle segment of splenic artery is the best choice.
