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.

摘要：

目的 介绍肝移植术后肝动脉 - 门静脉瘘的诊疗方法，并探讨肝动脉 - 门静脉瘘的介入治疗方法及效果。方法 天津市第一中心医院收治 2 例肝移植术后经皮经肝穿刺活检引发的肝动脉 - 门静脉瘘患者，经影像学确诊后，均采用经微导管弹簧圈栓塞瘘口治疗。结果 患者 1 经介入栓塞治疗后，门静脉主干宽度明显减少，血流恢复正常，脾大有所缓解，腹腔积液减少 ；患者 2 经介入栓塞治疗后，肝门区波动性包块消失，血流恢复正常。2 例患者的治疗证明以弹簧圈栓塞治疗肝动脉 - 门静脉瘘是安全有效的。结论 肝移植术后肝动脉 - 门静脉瘘一旦诊断明确，介入栓塞治疗是治疗该疾病的首选治疗手段。
