超声心动图分析78例动脉调转术前患儿冠状动脉的解剖类型

Echocardiographic Analysis of Coronary Artery Anatomy Pattern before Arterial Switch Operation

目的利用多普勒超声心动图分析准备行动脉调转手术(ASO)的患儿冠状动脉解剖类型,探讨其检查方法以更好地制定手术策略。方法回顾分析78例准备行ASO手术患儿超声心动图检查资料。结果78例患儿中,冠状动脉类型正常57例(73.1%),异常21例(26.9%)。冠状动脉起源于单个冠状动脉窦的类型占11例,为所有畸形中比率最高者(52.4%)。术前超声正确率可达89%。结论超声心动图可比较准确地检出ASO术前患儿的冠状动脉畸形,有利于冠状动脉移植方法的确定。

Objective To summarize the coronary artery pattern diagnosed by echocardiography before arterial switch operation and explore the echo skill in order to adopt appropriate technique for coronary ostis transfer. Methods Echocardiographic diagnosis of 78 children before arterial switch operation were retrospectively reviewed. Results The normal distribution of coronary arery was observed in 57 cases（73.1%） ,abnormal distribution in 21（26.9 %）. Coronary arteries originated from one coronary sinus （11 cases,52.4%） were the main variations. The accuracy of the consensus dianosis was 89%. Conclusion Anomalous coronary artery pattern diagnosed by echocardiography could benefit patients underwent arterial switch operation.
