Three-dimensional construction and anatomical variations of hepatic arteries based on 64-slice spiral CT scanning data / 解剖学报

ObjectiveTo 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.
