目的探讨胎儿心脏大动脉畸形的产前超声心动图诊断方法及操作技术路线。方法对已检出的117例胎儿复杂型先天性心脏病(先心病)合并大动脉畸形胎儿进行回顾性分析并与尸检和出生后手术及超声检查进行对比。结果117例复杂先心病胎儿的大动脉交叉图显示无交叉关系及交叉关系异常65例(55.5%);检出大动脉内径及瓣膜异常为51例占43.5%(其中大动脉内径异常35例;主动脉瓣/肺动脉瓣狭窄16例)。结论胎儿心脏大动脉畸形在胎儿心脏病诊断中属难度最大和最易发生漏诊,检查中应明确血流动力学异常改变及动态显示有无大动脉交叉切面及血管排列、内径、瓣膜形态及数量、瓣上和流出道等异常改变。
Objective To investigate the method of prenatal echocardiography and its technical route of operation. Methods A total of 117 fetuses with congenital heart disease complicated with arteriolar malformation were analyzed retrospectively and compared with autopsy and postnatal surgery and ultrasonography. Results A total of 117 cases with complicated congenital heart disease showed no cross-correlation and cross-correlation abnormalities in 65 cases (55.5%). 51 cases (43.5%) were detected with aortic diameter and valvular anomalies / Pulmonary valve stenosis in 16 cases). Conclusions Fetal heart malformations are most difficult to diagnose in fetal heart disease and most likely to occur. Misdiagnosis of abnormal hemodynamics should be made in the examination and the presence or absence of aortic cross-section and vascular alignment, internal diameter, shape and number of valves, Abnormal changes on and out of the road.
