目的：应用64排螺旋 CT 血管造影（computed tomography angiography，CTA）评价肝动脉血管变异。方法：对200例行64排螺旋 CT 检查的患者的肝动脉 CTA 资料进行分析，结合文献分析肝动脉解剖变异率及 CTA 对肝动脉解剖变异的诊断价值。结果：200例中，肝动脉解剖结构正常者166例，肝动脉解剖变异者34例。根据 Michels 分型，发现6种解剖变异，其中最多的是 Michels Ⅲ型（14例，7．0％），其次是 MichelsⅡ型（9例，4．5％），另有 Michels Ⅳ型2例（1．0％）、MichelsⅤ型 6例（3．0％）、MichelsⅥ型1例（0．5％）、MichelsⅨ型1例（0．5％），Michels 分型以外的1例（0．5％）。本研究中肝动脉变异发生率与既往文献明显不同。结论：肝动脉的变异率及变异分型具有不规律性，64排螺旋 CTA 能提供肝动脉解剖结构的信息，对制定合理的手术、介入治疗方案有重要意义。

Objective:To evaluate the anatomical variations of hepatic artery via 64-slice spiral computed tomography angiogra-phy (CTA).Methods:The data of 200 patients who underwent 64-slice spiral computed tomography angiography were assessed by comparing with previous literatures,so as to analyze the rate of anatomical variations of hepatic artery and evaluate the diag-nostic value of CTA on anatomical variations of hepatic artery.Results:There were 166 cases with normal anatomical structure of hepatic artery and 34 cases with anatomical variations of hepatic artery.According to Michels'classification,six kinds of variations were found.The most was Michels Ⅲ(14 cases,7.0%),and the followings were Michels II(9 cases,4.5%),Mi-chels Ⅳ type(2 cases,1.0%),Michels Ⅴ(6 cases,3.0%),Michels Ⅵ(1 case,0.5%),Michels IX(1 case,0.5%),and non-Michels(1 case,0.5%).There were significant differences between incidence rate of anatomical variations of hepatic artery in this study and those in previous literatures.Conclusions:The incidence rate and type of variations of hepatic artery are irregu-lar.Anatomical information on hepatic artery,which is significant for reasonable scheme of surgical operation and intervention-al therapy,can be provided by CTA.
