目的探讨胎儿心脏超声检查在产前筛查中的临床价值。方法选取1 872例孕22~28周的孕妇,采用GE VOLUSON E8彩色多普勒超声诊断仪由胸部至腹部各个切面逐一扫查的方法,对胎儿心内结构及血流情况进行系统筛查。将诊断为胎儿心脏发育异常的病例结果与孕妇引产后的尸检结果和新生儿心脏超声检查结果进行比较。结果 1 872例胎儿中共33例出现了心脏结构异常的情况,其中经产前胎儿心脏彩超筛查确诊30例,漏诊3例,胎儿心脏超声检查胎儿心脏畸形诊断准确率为90.91%。漏诊的为室间隔缺损(肌部)2例,肺静脉异位引流1例。结论胎儿心脏超声检查作为一种经济、实用且无创的检查手段,对于胎儿先天性心脏病的检出率较高,有助于降低此类缺陷患儿的出生率,更好地落实优生优育政策。
Objective To investigate the clinical value of fetal cardiac ultrasonography in prenatal screening. Methods A total of 1872 pregnant women with gestational age from 22 to 28 weeks were enrolled in this study. The fetal heart structure and blood flow were systematically screened by GE VOLUSON E8 color Doppler sonography. The results of the case diagnosed as fetal cardiac dysplasia were compared with post-abortion autopsy findings and neonatal cardiac ultrasonography in pregnant women. Results A total of 3372 fetuses had cardiac structural abnormalities. Among them, 30 cases were diagnosed by prenatal fetal color Doppler ultrasonography and 3 cases were misdiagnosed. The diagnostic accuracy of fetus cardiac ultrasound was 90.91%. Misdiagnosed ventricular septal defect (muscle) in 2 cases, anomalous pulmonary venous drainage in 1 case. Conclusion Fetal echocardiography as an economical, practical and noninvasive means of detection of fetal congenital heart disease detection rate is higher, helps to reduce the birth rate of children with such defects, to better implement the prenatal and postnatal care policy.
