目的:探究产前超声检查在中孕期胎儿严重先天性心脏病(CHD)筛查中的应用。方法:选择2012年1月至2014年1月在我院妇产科进行产前常规超声检查的孕妇12076例,年龄22-41岁,平均(28.6±8.3)岁,孕周20-36周,平均(25.2±6.7)周。将符合纳入排除标准的孕妇8953例作为研究对象,其中初产妇6023例,经产妇2930例。对纳入研究的孕妇行彩色多普勒超声检查,并对妊娠结局进行追踪,将确诊情况与筛查结果进行比较分析。结果:产前彩色多普勒超声诊断出胎儿CHD38例,经尸检或新生儿彩色多普勒超声检查均确诊为CHD,对胎儿期未筛查出CHD的孕妇进行新生儿彩色多普勒超声检查,确诊4例,产前超声检查胎儿CHD检出率为90.48%(38/42),检出准确率100%(38/38)。结论:彩色多普勒超声筛查孕中期胎儿CHD,灵敏度和特异性高,安全无创伤,操作简便快速,值得推广为产前筛查的首选方法。
Objective: To investigate the application of prenatal ultrasound in the screening of fetus with severe congenital heart disease (CHD) in the second trimester. Methods: From January 2012 to January 2014, 12076 pregnant women undergoing prenatal routine ultrasound examination in our department were selected, aged 22-41 years, mean (28.6 ± 8.3) years, gestational weeks 20-36 weeks, Average (25.2 ± 6.7) weeks. Eight 953 pregnant women who met the exclusion criteria were included as study subjects, of which 6023 were primipara and 2930 were mothers. Color Doppler sonography was performed on pregnant women included in the study and the pregnancy outcome was tracked. The diagnoses and screening results were compared. Results: Prenatal color Doppler ultrasonography diagnosed 38 cases of fetal CHD, autopsy or neonatal color Doppler ultrasound were diagnosed as CHD, fetus did not screen for CHD in pregnant women for neonatal color Doppler ultrasound , Diagnosed in 4 cases, fetus CHD detection rate of prenatal ultrasound was 90.48% (38/42), the detection accuracy was 100% (38/38). Conclusion: Color Doppler ultrasound screening for fetal metaphase fetus CHD, high sensitivity and specificity, safe and noninvasive, easy to operate, it is worth promoting the preferred method for prenatal screening.
