摘　　要：目的:探讨64层螺旋CT诊断冠状动脉起源异常的价值及对预后的评价。方法:对1211例冠状动脉CT血管成像(CTA)资料进行回顾性分析。结果:1211例完整冠状动脉CTA结果中,共检出冠状动脉起源异常18例,检出率为2.17%。包括右冠状动脉起源于左窦5例,伴前降支和回旋支单开口1例;右冠状动脉起源于升主动脉1例;圆锥动脉单开口4例;左冠状动脉主干起源于右窦3例;回旋支起源于右窦1例。前降支和回旋支单开口4例;共有8例冠状动脉分别起源于对侧窦,其中有3例该段有50%左右狭窄。结论:64层螺旋CT是冠状动脉起源异常安全和有效的确诊方法,并可对预后做出评估。Objective： To assess the value of 64 muhislice spiral CT for evaluation of the origin of coronary artery anomalies and prognosis. Methods： 1211 patients undergone coronary artery CT angiography （CTA） were reviewed for this study. Results： In consecutive 1211 patients, 64 MSCT identified 18 cases （2.17%） with an anomalous origin of the coronary artery, including anomalous origin of the fight coronary artery from left coronary sinus（n=5）, anomalous high origin of the fight coronary artery（n=l）, separate origin of CB from fight sinus（n=4）, anomalous origin of the left coronary artery from fight coronary sinus（n=3）, left circumflex coronary artery from fight sinus（n=l）, separate origin of left circumflex coronary artery and left anterior descending arteries from left coronary sinus （n=5）. Three coronary arteries in 8 patients with anomalous origin showed mild stenosis. Conclusion： Noninvasive 64 MSCT can detect the anomalous origin of the coronary artery with high resolusion, and can evaluate the prognosis of the anomalous origin coronary artery.
