摘　　要：目的探讨肝动脉解剖变异情况及其临床意义。方法采用自行设计软件MIPS三维重建66例螺旋CT扫描数据中的肝动脉,根据Michels分型标准进行解剖变异分型。结果三维重建肝动脉形态逼真、立体感强。正常型40例,占60.61%;变异肝动脉26例,变异率为39.39%;未列入Michels分型的少见变异5例,占7.58%。结论肝动脉三维模型可以立体显示其解剖变异的各种类型。Objective To study the types of anatomical variations of hepatic arteries. Methods Hepatic arteries of 64-slice spiral CT scanning data were three-dimensional constructed by using selfdesigned software. The types of anatomical variations were analyzed and classified with Michels’ classification criteria. Results The model presented with realistic profile of hepatic arteries which allowed vivid three-dimensional observation. Of these patients, 40 had normal hepatic arteries （60.61%）, 26 had variations （3939%）, and 5 had infrequent aberrant hepatic arteries that was not included in Michels’ classification （7.58%）. Conclusion Threedimensional model of hepatic arteries can volumetricly display the anatomical variations of hepatic arteries.
