摘　　要：目的：应用64排螺旋CT血管成像探讨活体肝动脉解剖学分型及变异,为临床肝手术的顺利实施提供形态学资料.方法：采集200例受试者肝CT图像,经容积再现技术重建肝动脉.按照Michels分型方法观察肝动脉的解剖学形态和变异情况.结果：依据Michels分型方法,肝动脉的分型如下：正常解剖型148例.肝动脉起源变异者占26.0%,其中,属于Michels分型中变异者有4种共30例,Ⅲ型占6.5%、Ⅱ型占3.0%、Ⅴ型占5.0%、Ⅸ型占0.5%;Michels分型以外者有22例,其中肝总动脉3分叉型占4.0%、肝右动脉起自胃十二指肠动脉型占3.5%、肝右动脉起自腹腔干型占1.5%、还有4例为极少见型.结论：基于肝动脉变异的多样性和复杂性,以肝动脉起源变异和供血范围为标准来分型,更有利于临床应用.Objective： To investigate the anatomical type and variations of living hepatic artery with 64-multi-slice computed tomography angiography（64-MSCTA）, and to provide morphological information for the operation of liver interventional therapy and liver transplantion. Methods： CT images of 200 volunteers were collected and dealt with volume rendering techniques. The type of variation was classified with Michels＇ classification. Results： According to the Michels＇ classification, 148 cases were normal, and a total of 52 hepatic artery anatomic variations were detected in 200 case. There were 30 cases which were classified into Michels types. Michels type Ⅲ were 13 cases, Ⅱ 6 cases, V l0 cases, Ⅺ1 cases. There were 22 hepatic artery anatomic variations which could not be included in the Michels＇ classification. Three common hepatic artery bifurcation occured in 8 cases, while the right hepatic artery arising from the gastroduodenal artery occured in 3.5 of cases. The type of the right hepatic artery arising from celiac artery were 1.5 of all. 4 cases were in extreme rare type. Conclusion： The variations of the hepatic artery are complex. The variation classification of anomalous origin in the hepatic artery is benefit to liver transplantion and transcathetal chemoembolization.
