目的探讨超声在产前筛查胎儿先天性心脏病中的应用,以提高胎儿先天性心脏病的检出率。方法采用二维超声、彩色多普勒技术筛查胎儿心脏病。主要取四腔心、左室流出道、右室流出道为主要切面,对3 986例孕18周以上孕妇的胎儿心脏进行初步筛查,发现259例胎儿心脏异常。结果259例胎儿中,经产后复查或引产后尸检证实,发现先天性心脏病36例,其中33例有先天性心脏畸形,占91.67%;漏诊3例,占8.33%。敏感性86.84%,特异性100%,准确性99.49%。结论二维超声和彩色多普勒技术是产前筛查胎儿先天性心脏病的首选方法,能够发现大多数胎儿心脏畸形,是预防和控制先天性心脏病胎儿出生的有效措施,也可作为初步筛查复杂先天性心脏病的方法。
Objective To investigate the application of ultrasound in prenatal screening for fetal congenital heart disease in order to improve the detection rate of fetal congenital heart disease. Methods Two-dimensional ultrasound and color Doppler were used to screen fetal heart disease. Mainly take the four-chamber heart, left ventricular outflow tract, right ventricular outflow tract as the main section, a preliminary screening of 3 986 pregnant women more than 18 weeks of fetal heart fetal and found 259 cases of fetal heart abnormalities. Results Totally 259 fetuses were confirmed by post-mortem examination or post-abortion autopsy. Thirty-six cases of congenital heart disease were found, of which 33 cases had congenital heart malformation, accounting for 91.67%; 3 missed diagnosis, accounting for 8.33%. Sensitivity 86.84%, specificity 100%, accuracy 99.49%. Conclusion Two-dimensional ultrasound and color Doppler ultrasound is the first choice for prenatal screening for fetal congenital heart disease. It can detect most of the fetal cardiac malformations and is an effective measure to prevent and control the birth of fetuses with congenital heart disease. Methods of screening for complex congenital heart disease.
