64层螺旋CT冠状动脉血管成像诊断冠状动脉变异的价值

目的：评价64层螺旋CT冠状动脉血管成像（CTA）在诊断各种类型冠状动脉变异中的价值和临床应用。方法：回顾性分析617例行冠状动脉CTA检测患者的冠状动脉变异检出率，并根据CT结果对冠状动脉变异进行分类。结果：617例冠状动脉CTA受检者中，共检出冠状动脉变异78例（12．64％，78／617），其中右冠状动脉起自主动脉左冠状窦者9例，左冠状动脉起自主动脉右冠状窦者2例，右冠状动脉开口高位者2例，多开口变异者2例（并行左主干），心肌桥者59例．前降支．肺动脉瘘者2例，左右冠状动脉一肺动脉瘘者l例，右冠状动脉一左室瘘合并右冠状动脉瘤者1例。结论：冠状动脉CTA能准确评估冠状动脉变异，并可清晰显示各类病变细节，可作为无创性诊断冠状动脉变异的首选方法。

Diagnostic value of 64-slice multi-detector row spiral CT coronary angiography in patients with coronary artery anomalies

Objective To evaluate the diagnostic value of 64-slice multi-detector row spiral CT coronary angiography in patients with coronary artery anomalies.Methods The value of 64-slice multi-detector row spiral CT angiography in detecting coronary artery anomalies in 617 patients was retrospectively analyzed.Results Seventy-eight cases(12.64%,78/617) of coronary artery anomalies were detected by 64-sclice multi-detector row spiral CT angiography.The anomalies consisted of 9 cases of right coronary artery originated from left aortic sinus,2 case of left coronary artery originated from right aortic sinus,2 cases of right coronary artery with high take-off origin,2 case of multiple coronary ostia,59 cases of myocardial bridging,2 cases of LAD-PA fistula,1 case of bilateral coronary artery-pulmonary artery fistula,1 case of RCA-LV fistula with RCA aneurysm.Conclusions 64-slice multi-detector row spiral CT coronary angiography can accurately evaluate coronary artery anomalies and show details of different types of anomalies.It is recommended as the first-line non-invasive method for diagnosing coronary artery anomalies.
