Abstract:

Objective To introduce the diagnosis and treatment methods for hepatic artery-portal veinfistula after liver transplantation，and to explore the procedure and efficacy of intervention therapy. Methods2 patients suffered hepatic artery-portal vein fistula after liver transplantation caused by percutaneous liverbiopsy，and were treated with microcoil embolization of the fistula after radiological diagnosis in Tianjin first centerhospital. Results In case 1，portal vein width reduced significantly after embolization with blood flow returned to normal，splenomegaly decreased，and ascites reduced. In case 2，hepatic hilar pulsatile mass disappeared afterembolization with restoration of normal blood flow，which proved microcoil embolization was a safe and effectivemethod for hepatic artery-portal vein fistula. Conclusion Once post-transplant hepatic artery-portal vein fistulais diagnosed，interventional embolization is the preferred treatment.
