摘　　要：目的探讨产前超声诊断胎儿主动脉闭锁的临床价值。方法回顾性分析9例经引产后尸检证实的主动脉闭锁胎儿的产前超声心动图表现，总结其声像图特征。结果9例主动脉闭锁胎儿声像图显示升主动脉及主动脉弓细窄7例，升主动脉及主动脉弓显示不清2例，彩色多普勒血流显像9例胎儿均显示主动脉与左心室无血流连接，主动脉弓显示反向血流。9例胎儿中6例伴发左心发育不良，2例伴发室间隔缺损，左心室发育良好，1例伴发完全型房室间隔缺损。9例胎儿检出时平均孕龄（26．0±2．6）周，孕龄最小者仅为孕16周。结论产前超声诊断胎儿主动脉闭锁具有重要临床价值；升主动脉、主动脉弓细窄或显示不清，主动脉与左心室无血流连接及主动脉弓内反向血流是主要诊断依据；彩色多普勒血流显像有助于早期诊断。Objective To investigate the clinical value of prenatal ultrasonography in diagnosing fetal aortic atresia. Methods Ultrasound images of 9 cases with fetal aortic atresia confirmed by autopsy were retrospectively analysed and summarized. Results Fetal echocardiography showed ascending aorta and aortic arch were thin in seven cases and unclear in two cases. Color Doppler flow imaging showed fetal aorta no blood connection with left ventricle and reverse blood flow in aortic arch among all 9 cases. There were 6 cases associated with hypoplastic left heart syndrome, two cases associated with ventricular septal defect and well-developed left ventricle, one case complicated with complete atrioventricular septal defect. Nine cases were detected at average gestationa[ age （26.0±2.6） weeks, minimum gestational age was only 16 weeks pregnant. Conclusions Prenatal ultrasound diagnosis of fetal aortic atresia has important clinical value. Ascending aorta and aortic arch are thin or unclear, no blood flow connection between fetal aorta and left ventricle and reverse blood flow in aortic arch are major diagnostic evidences. Color Doppler flow imaging is helpful for early diagnosis.
