摘要
目的:探讨双源CT血管成像对冠状动脉异常起源的诊断价值。方法:对8375例成人冠状动脉双源CT血管成像中109例显示为冠状动脉异常起源的图像进行回顾性分析。结果:本组中冠状动脉起源异常检出率为1.3%(109/8375),包括左侧冠状动脉起源异常37例(窦上开口4例,窦后开口4例,回旋支异位开口于右侧冠状窦8例,回旋支独立开口于左冠状窦15例,左冠开口于右冠状窦或右冠状动脉4例,左冠开口于肺动脉1例,回旋支缺如1例),右侧冠状动脉起源异常61例(高位开口29例,异位开口于左冠状窦24例,圆锥支独立开口8例),左、右冠状动脉均起源异常11例;109例起源异常中发现伴随冠状动脉肺动脉瘘2例,心肌桥4例。结论:双源CT可以准确诊断冠状动脉起源异常,并可发现其它伴随病变,是一种无创有效的检查方法。
Objective：To assess the diagnostic value of dual-source CT angiography for evaluation of the anomalous origination of coronary artery.Methods：8375 adult patients undergone coronary artery CT angiography（CTA）,including 109 cases with anomalous arterial origination were analyzed retrospectively.Results：In consecutive 8375 patients,DSCT identified 109 cases（1.3%）with anomalous origination of the coronary artery,including anomalous origination of the right coronary artery（n=61）consisted of surperior origination（n=29）,ectopic origination from left coronary sinus（n=24）and single conical branch（n=8）,anomalous origination of the left coronary artery（n=37）with supra-sinus origination in 4,retro-sinus origination（n=4）,ectopic circumflex origination from right coronary sinus（n=8）,single circumflex origination from left coronary sinus（n=15）,left coronary artery origination from right coronary sinus or right coronary artery（n=4）,left coronary artey origination from pulmonary artery（n=1）and circumflex agenesis in 1,anomalous origination of both the left and right coronary arteries（n=11）;In the 109 cases there were two cases of coronary-pulmonary artery fistula and four of myocardial bridging.Conclusion：DSCT can accurately diagnose the anomalous origination of coronary artery associated with other disorders,and provide a non-invasive and effective method.
