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16层螺旋CT对242例患者行肝动脉CT血管成像检查。分析肝动脉及其分支的解剖走行情况,根据Michels分型标准进行解剖变异分型。结果:正常型169例,占69.8%;变异肝动脉73例,变异率为30.2%。未列入Michels分型的少见变异25例,占10.3%。结论:肝动脉解剖变异复杂,多层螺旋CT血管成像(MSCTA)有必要列为介入治疗、外科手术尤其肝移植前的常规检查。Objective： To discuss the types of anatomical variations of hepatic arteries. Methods： Hepatic arteriography was given to 242 patients by using the 16-slice MSCT. The anatomical variations of hepatic arteries were analyzed and classified with Michels＇ classification criteria. Results： Of these patients, 169 had normal heptic arteries （69.8%）, 73 had variations （30.2%）, and 25 had infrequent aberrant hepatic arteries not included in Michels＇ classification （10.3%）. Conclusion： The variation of hepatic arteries is complex. It is necessary for surgeons to evaluate hepatic arteries by MSCTA before interventional therapy, surgery and liver transplantation.
