摘要
目的：分析产前超声诊断胎儿主动脉弓异常的超声特征及结局,了解胎儿主动脉弓异常的畸形特征,提高主动脉弓异常的产前超声诊断率。方法：选择2006~2009年在深圳市妇幼保健院行产前系统超声检查并获得结果验证的91例胎儿主动脉弓异常者做为研究对象,分析其产前超声诊断、畸形特征及结局。结果：本组研究通过常规心脏筛查切面加主动脉弓特殊切面,产前超声共诊断148例主动脉弓异常,漏诊1例主动脉弓缩窄,91例获得结果验证,包括主动脉弓缩窄30例,主动脉弓离断7例,主动脉弓缩窄和离断在三血管气管平面（3VTV）上显示主动脉内径小,主动脉/肺动脉内径比例失调;右位主动脉弓及主动脉弓分支异常52例,双主动脉弓2例,两者在3VTV显示主动脉弓和动脉导管之间距离增大。24例合并其他严重心脏畸形,7例染色体异常,28例合并心外畸形。主动脉弓异常的产前超声诊断率为92.5%（86/93）。在未合并其他严重心脏畸形的68例中有61.8%（42/68）新生儿结局良好。结论：超声是诊断胎儿各种主动脉弓异常的一种主要方法,三血管气管平面上主动脉内径小、主动脉/肺动脉内径比例失调及其之间距离增大是诊断主动脉弓异常的线索,主动脉弓异常可能合并其他严重心内外畸形和/或染色体异常,也可不合并其他严重心内外畸形,后者预后良好。
Objective：To analyze the ultrasonic features and outcomes of fetal aortic arch anomaly diagnosed by prenatal ultrasonography,understand the pathognomonic features of fetal aortic arch anomaly,improve the diagnosis rate of prenatal ultrasonography for fetal aortic arch anomaly.Methods：91 fetuses with aortic arch anomaly who received prenatal systematical ultrasonography and were diagnosed definitely in the hospital from 2006 to 2009 were selected as study objects.The prenatal ultrasonic diagnosis,pathognomonic features and outcomes were analyzed.Results：148 fetuses with aortic arch anomaly were diagnosed by prenatal ultrasonography through conventional heart screening views and special views of aortic arch,one fetus with coarctation of aortic arch was missed diagnosed,91 fetuses were diagnosed definitely,including 30 fetuses with coarctation of aortic arch,7 fetuses with interrupted aortic arch（IAA）,coarctation of aortic arch and interrupted aortic arch showed small aortic diameter and unbalance of aortic diameter/pulmonary artery diameter ratio in three vessel trachea view（3VTV）;52 fetuses with right-side aortic arch and abnormal aortic branch,2 fetuses with double aortic arch were also included,the increased distance between aortic arch and arterial duct was showed in 3VTV.24 fetuses were combined with other severe cardiac anomalies,7 fetuses were combined with chromosomal abnormalities and 28 fetuses were combined with extracardial anomalies.The diagnosis rate of prenatal ultrasonography of aortic arch anomaly was 92.5%（86/93）.Among 68 fetuses without other severe cardiac anomalies,42 neonates（61.8%） had good outcomes.Conclusion：Ultrasonography is a main method to diagnose various fetal aortic arch anomalies;small aortic diameter,unbalance of aortic diameter/pulmonary artery diameter ratio and the increased distance between aortic arch and arterial duct in 3VTV are clues for diagnosis of aortic arch anomaly,aortic arch anomaly may combine with other severe cardiac anomalies and extracardial anomalies or not,the prognosis of the latter is good.
