【摘要】：目的胎儿动脉导管(DA)异常的超声心动图检查及分析。方法回顾性分析产前诊断DA异常的70胎资料。二维超声结合彩色多普勒扫查胎儿四腔心切面、左右心室流出道切面、三血管切面及三血管—气管切面等横断面,扫查腔静脉长轴切面、主动脉弓切面及动脉导管弓切面等矢状面。观察DA的走行及与其他大血管的空间位置关系。结果胎儿DA异常主要由DA缺如、DA功能异常及DA形态异常3类。70胎DA异常中,9胎DA缺如,8胎DA早闭,11胎DA即将闭合,9胎DA逆行灌注血流,33胎DA走行纡曲伴扩张。结论产前诊断胎儿DA缺如及DA功能性改变意义重大。三血管—气管切面及动脉导管弓切面结合CDFI扫查可明确诊断。
[Abstract]:Objective to examine and analyze fetal ductal ductus arteriosus (DAA) abnormalities by echocardiography. Methods 70 fetuses with antepartum DA abnormalities were retrospectively analyzed. Left and right ventricular outflow tract section, trivascular section and trivascular tracheostomy cross section, scanning the long axis of vena cava. The isosagittal plane of aortic arch and ductus arteriosus was observed. The path of DA and the spatial relationship between DA and other large vessels were observed. Results the main abnormality of DA in fetus was the absence of DA. Abnormal DA function and DA morphologic abnormality of 3 types. 70 cases of DA abnormality in 9 cases were as follows: 8 cases of DA early occlusion 11 cases of DA about to close and 9 cases of DA retrograde perfusion of blood flow. Conclusion prenatal diagnosis of fetal DA deficiency and DA functional changes is of great significance. Three-vessel tracheostomy and Arterial Catheter Arch Section combined with CDFI scan can be clearly diagnosed.

【正文快照】： 目前,胎儿超声心动图是诊断胎儿先天性心脏病(先心病)的重要手段。随着对胎儿心脏产前诊断水平的提高,多数胎儿先心病均可通过产前超声诊断,包括室间隔缺损、圆锥动脉干畸形、弓动脉异常、肺静脉异位引流等。动脉导管(ductus arteriosus,DA)是胎儿时期心脏大血管的重要解剖结
