【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。更多还原

【Abstract】 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.更多还原
