Abstract:
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.
