应用超声心动图对先天性主动脉弓畸形病例的分析

Echocardiographic diagnosis of congenital malformations of aortic arch

目的应用超声心动图观察分析先天性主动脉弓畸形的类型。方法回顾分析以往病例检查中31例先天性主动脉弓畸形患者的超声心动图表现。所选病例均经手术或心血管造影(CAG)证实。结果31例先天性主动脉弓畸形患者中,右位主动脉弓(RAA)18例(2例伴有椎动脉自主动脉弓发出),主动脉缩窄(COA)5例,主动脉弓部曲折畸形3例,单纯头臂干(无名动脉)发出异常2例,肺动脉单发于主动脉弓2例(1例伴有头臂干发出异常),主动脉弓离断(IAA)1例,其中27例合并其他心内畸形。结论超声心动图对于诊断先天性主动脉弓畸形是一种有效、无创、经济的检查手段,可作为诊断的首选方法。

Objective To investigate the types of congenital malformations of aortic arch by using echocardiography. Methods The echocardiographic images of 31 patients of congenital malformations of aortic arch were retrospectively analyzed. And all cases were confirmed by surgery or cardiac angiography. Results Of the 31 cases, 18 patients were of right aortic arch （RAA）（including 2 of vertebral artery originated from aortic arch）, 5 of coarctation of the aorta （COA）, three of flexuous aortic arch, 2 of simplex anomalous origination of brachiocephalic artery, 2 of pulmonary artery originated from aortic arch （including 1 of anomalous origination of brachiocephalic artery） and 1 of interruption of aortic arch （IAA）. Twerty-sev- en patients were also associated with other cardiac anomalies. Conclusion Echocardiography is a valuable, harmless and relatively economical method to diagnose congenital malformations of aortic arch, which should be chosed firstly.
