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。
Abstract
Objective: To assess the value of 64 multislice 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 right coronary artery from left coronary sinus(n=5), anomalous high origin of the right coronary artery(n=1), separate origin of CB from right sinus(n=4), anomalous origin of the left coronary artery from right coronary sinus(n=3), left circumflex coronary artery from right sinus(n=1), 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.
