肝移植术后急性肝动脉闭塞的介入治疗

目的评价介入医学在诊断和治疗肝移植术后急性肝动脉闭塞中的作用.方法对7例原位肝移植术后急性肝动脉闭塞病例的诊断和介入治疗过程进行了回顾性分析.结果 59例肝移植术后血管造影证实存在肝动脉闭塞7例,其中多普勒超声发现5例;经导管溶栓治疗,7例肝动脉闭塞中5例部分或全部开通,对其中4例进行了血管内支架植入治疗,经1～13个月随访,肝动脉血流通常,避免了再次肝移植.结论血管造影对肝移植后肝动脉并发症的诊断具有重要价值,介入手段是处理肝移植术后急性肝动脉闭塞的有效方法.

Interventional treatment for acute hepatic artery occlusion after liver transplantation

Objective To determine the value of interventional method for diagnosis and treatment of acute hepatic artery occlusion after liver transplantation. Methods The clinical data of 7 patients with acute hepatic artery occlusion after liver transplantation receiving interventional treatment in our hospital were retrospectively analyzed. Results Of the 7 cases found by angiography, 5 were diagnosed by Doppler ultrasonography. After transcatheter thrombolysis, the hepatic artery was patent again partially or totally in 5 cases. The stent placement in hepatic artery was performed in 4 cases. The stent proved patent and no patient needed another liver transplantation. Conclusions Angiography plays an important role in diagnosis of the hepatic complication after liver transplantation. Interventional therapy is a valuable method for treatment of acute hepatic artery occlusion after liver transplantation.
