【摘要】 目的 以64排螺旋CT冠状动脉血管造影(CTA)的方法分析成人冠状动脉起源变异的发生率及主要形式。方法以5 011例有诊断价值的冠状动脉CTA图像作为研究对象,观察冠状动脉起源变异的发生及表现形式。结果 5 011例病例中,共发现冠状动脉起源变异32例(0.64%)。其中右冠状动脉起源于左冠状动脉窦最多见(21/32)。其次为回旋支起源于右冠状动脉窦(7/32),左主干起源于右冠状动脉窦(4/32)。结论 冠状动脉起源变异罕见。冠状动脉起源变异的主要形式为右冠状动脉起源于左冠状动脉窦。64排冠状动脉CTA可以准确发现冠状动脉起源异常,是相对无创、精确的检查方法。更多还原

【Abstract】 Objective To investigate the incidence and form of anomalous origin of coronary artery with 64-slice CT angiography(CTA) in adult.Methods The coronary CTA images of the total 5 011 adult patients were retrospectively analyzed.Results Among the total 5011 cases,there were 32 patients with anomalous origin of coronary artery,including right coronary artery(RCA) from left coronary sinus in 21 cases,which was the most common.Others included left circumflex coronary artery(LCx)from right coronary sinus in 7 cases and left main coronary artery(LM) from right coronary sinus in 4 cases.Conclusion Anomalous origin of coronary artery is rare.RCA from left coronary sinus is most common in this study.As an invasive and accurate method,64-slice CT angiography can found anomalous origin of coronary artery delicately.更多还原
