摘　　要：目的:探讨CTA检查在显示冠状动脉异常起源中的作用,冠状动脉异常起源的分类及其临床意义。材料与方法:采用64层螺旋CT行冠状动脉CTA检查25 596例,运用容积再现、多平面及曲面重建、最大密度投影等技术分析冠状动脉的起源情况。结果:共检出冠状动脉异常起源263例,其中右冠状动脉起源异常171例,左冠状动脉起源异常86例,双窦畸形6例,并对冠状动脉异常起源类型与临床综合分析,改动前人的分型。结论:冠状动脉CTA能清晰显示冠状动脉异常起源的各种类型,对临床有一定的指导意义。Objective： To investigate the role of CTA examination in displaying the anomalous origin of coronary artery, and showing the classification and the clinical significance based on CTA in detecting this disease. Materials and Methods： Coronary CTA examinations were performed in 25 596 cases by 64 multi-slice spiral CT. Volume rendering, multi planar and curved surface reconstruction and maximum intensity projection were used to analyze the origin of the coronary artery. Re- suits： The anomalous origin of coronary artery was found in 263 cases, including 171 cases of anomalous origin of right coro- nary artery, 86 cases of anomalous origin of left coronary artery, and 6 cases of double sinus malformation. According to the comprehensive analysis of the classification and the clinical manifestation of this disease, we modified the previous classifica- tion. Conclusion： CTA could display various types of anomalous origin of the coronary artery clearly, showing great importance in guiding clinical practice.
