Abstract:
Objective To compare computed tomography angiography (CTA) and digital subtraction angiography (DSA) in identifying anatomical variation of hepatic artery.Methods A retrospective analysis was made on 220 patients who underwent both CTA and DSA in our hospital.The volume rendering (VR) reconstruction of CTA images was performed.The image quality and the recognition of hepatic artery anatomic variation between CTA and DSA were compared.Results There was a significant difference in the image quality of hepatic artery between the two imaging methods (x2 =88.016,P =0.000),DSA was superior to CTA.There was no significant difference in the accuracy of hepatic artery anatomical identification between CTA and DSA (x2 =0.252,P =0.615).This study has found five other types of hepatic artery anatomical variation besides Micheles types.Conclusion The anatomical variation of hepatic artery is complex,and there are many other variations besides Micheles types.CTA,as a noninvasive method,can provide sufficient information for hepatic artery anatomy.
