【摘要】：目的探讨胎儿完全性大动脉转位(TGA)的超声心动图特征。方法回顾性分析2010年1月—2017年1月经引产后尸体解剖证实或经出生后超声心动图检查证实为TGA的9胎胎儿的产前超声资料。结果 9胎TGA胎儿四腔心切面均显示正常的心轴及房室连接关系;左心室流出道切面8胎出现"雏鸟喙"征;左右心室流出道切面8胎2条大动脉(主动脉、肺动脉)呈平行关系;三血管气管(3VT)切面6胎仅显示2条大血管;主动脉弓切面7胎显示主动脉弓弧度不同程度增大。四腔心切面及左心室流出道切面均可见4胎室间隔上段缺损。结论 TGA胎儿超声心动图左心室流出道切面、左右心室流出道切面、3VT切面及主动脉弓切面均具有特征性表现,包括"雏鸟喙"征、2条大动脉呈平行关系、3VT切面仅显示2条大血管、主动脉弓弧度增大,其中以"雏鸟喙"征最为常见。
[Abstract]:Objective to investigate the complete transposition of the great arteries of the fetus (TGA). Methods Antepartum echocardiographic data of 9 fetuses with TGA confirmed by autopsy or postnatal echocardiography from January 2010 to 2017 were retrospectively analyzed. Material. The normal relationship between atrioventricular junction and axial axis was observed on the four-chamber section of TGA fetus in 9 fetuses. The "nestling beak" sign appeared in 8 fetuses of left ventricular outflow tract. Two great arteries (aorta and pulmonary artery) were parallel to each other on the left and right ventricular outflow tract. There were only 2 large vessels on the cut plane of 3 vascular tracheobronchial trachea (3 V T). The aortic arch in 7 fetuses showed an increase in aortic arch radians to varying degrees. Four lumen incisors and left ventricular outflow tract sections were found in 4 fetal upper ventricular septal defects. Conclusion\\\; TGA fetal echocardiography left ventricular outflow tract section. The 3VT section of left and right ventricular outflow tract and the aortic arch had characteristic features, including the "beak" sign of "nestling bird" and the parallel relationship between the two great arteries. Only two large vessels were displayed on the plane of 3VT section of left and right ventricular outflow tract. The arc of aortic arch is increased, and the "beak" sign is the most common sign.

【正文快照】： 完全性大动脉转位(complete transposition of great arteries,TGA)是一种严重的发绀型先天性心脏病,约占先天性心脏病的5%~7%[1]。多数TGA患儿主要依靠房间隔缺损、室间隔缺损或动脉导管未闭维持生命,未合并体-肺循环分流的TGA患儿如果不能及时手术治疗,出生后第2天即可能死
