【摘要】 目的 探讨肝癌的变异动脉供血规律，旨在指导肝癌的介入治疗。方法 998例肝癌动脉栓塞前常规腹腔动脉造影或肝总动脉造影，对疑有肝动脉变异的再行肠系膜上动脉和/或腹主动脉造影，分析DSA图像。结果 肝动脉呈典型分布者793例，占79.5%，肝动脉变异者205例，占20.5%，156例患者其肿瘤是由变异动脉供血，占肝癌患者的15.6%(156/998)，其中由变异肝右动脉供血者72例，由变异肝左动脉供血者56例，由变异肝总动脉供血者28例。由变异的肝左或肝右动脉供血的肝肿瘤128例，其中位于肝右叶的肿瘤有71例，67例由变

    异肝右动脉供血，4例由变异肝左动脉供血;位于肝左叶的肿瘤有57例，52例由变异肝左动脉供血，5例由变异肝右动脉供血。结论 熟悉肿瘤变异动脉供血，才能确保肝动脉插管的准确性和化疗栓塞的彻底性。

    【Abstract】 Objective To study the law of the pattern aberrant hepatic artery supply to hepatocellular carciˉnoma for directing interventional therapy.Methods Routine celiac arteriography before transarterial emobolization was underwent in998patients with liver cancer.In these cases with suspected anatomic variants of hepatic arteries，superiˉor mesenteric arterigraphy and/or abdominal aortography was undertaken.The imaging of digital substraction angiogrˉpahy(DSA)was analyzed.Results The distribution of hepatic arteries was showed as typical in793cases(79.5%)and the variants of hepatic arteries were in205cases(20.5%).Aberrant hepatic artery supply was found in156paˉtients(15.6%.156/998)with liver cancer ......
