摘　　要：目的对照分析计算机断层成像血管造影(computed tomography angiography,CTA)和数字减影血管造影(digital subtraction angiography,DSA)对肝动脉解剖变异的识别情况。方法回顾性分析在我院同时行CTA和DSA诊疗的患者220例,将CTA图像进行容积再现(volume rendering,VR)重建,评价CTA行VR重建后图像和DSA图像质量对肝动脉解剖变异的识别情况。结果两种成像方法显示肝动脉图像质量的差异有统计学意义(χ2=88.016,P=0.000),DSA优于CTA;CTA与DSA对肝动脉解剖识别准确性的差异无统计学意义(χ2=0.252,P=0.615)。本研究除了显示肝动脉解剖变异的Micheles分型外,还发现了Micheles分型外的5种变异类型。结论肝动脉解剖变异复杂,除Micheles分型外,还存在其他多种变异;CTA作为一种无创的方法能够对肝动脉解剖提供足够信息。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 (χ2=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 (χ2=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 non-invasive method,can provide sufficient information for hepatic artery anatomy.
