摘　　要：目的:探究四维彩超联合系统B超在胎儿先天性畸形筛查中的应用价值;方法:选取2016年1月至2017年1月体格检查的780例妊娠女性为研究对象,孕妇均采用四维彩超及系统B超检查进行胎儿先天性畸形排查。对比两种方法的准确率、灵敏度、特异度。结果:以引产/分娩结果为金标准,780例新生儿中畸形胎儿18例,四维彩超检查准确率为94.44%(17/18),系统B超检查准确率为66.67%(12/18),两组对比差异具有统计学意义(P<0.05) ;两种检查方式灵敏度一致,均为100.00%,系统B超检查特异度为99.28%,思维彩超特异度为99.87%;经误诊分析,发现四维彩超受妊娠时间、胎儿体位及羊水含量影响较大,系统B超检测准确率较低,但孕早期即可使用。结论:四维彩超及系统B超在胎儿先天性畸形筛查中均具有较高的准确度和敏感度,但两种检测方式均具有一定的缺陷,联合检测的方式能够提高检测准确率,效果较好。准,780例新生儿中畸形胎儿18例,四维彩超检查准确率为94.44%(17/18),系统B超检查准确率为66.67%(12/18),两组对比差异具有统计学意义(P<0.05);两种检查方式灵敏度一致,均为100.00%,系统B超检查特异度为99.28%,思维彩超特异度为99.87%;经误诊分析,发现四维彩超受妊娠时间、胎儿体位及羊水含量影响较大,系统B超检测准确率较低,但孕早期即可使用。结论:四维彩超及系统B超在胎儿先天性畸形筛查中均具有较高的准确度和敏感度,但两种检测方式均具有一定的缺陷,联合检测的方式能够提高检测准确率,效果较好。Objective： To investigate the value of B-ultrasound in the screening of fetal congenital malformations by four-dimensional ultrasonography. Methods： 780 pregnant women who underwent physical examination in our hospital from January 2016 to January 2017 were selected as study subjects. All pregnant women was used four-dimensional color ultrasound and system B-ultrasound for the checking of fetal congenital malformations. The accuracy,sensitivity,and specificity of the two methods was compared. Results： The results of labor induction/delivery was used as the gold standard,there were 18 malformation fetuses in 780 newborns,the accuracy rate of four-dimensional ultrasonography was 94.44%（17/18）,the accuracy of system B-ultrasound was 66.67%（12/18）,and the difference between the two groups was statistically significant（P 0.05）; The sensitivity of the two examination methods was the same,both being 100.00%. The specificity of the system B-ultrasound was 99.28%,and the specificity of the color Doppler ultrasound was 99.87%; Misdiagnosis analysis found that four-dimensional color Doppler ultrasound by pregnancy time,fetal position and amniotic fluid content greater impact,the system B-ultrasound detection accuracy lower but can be used during early pregnancy; Conclusion： The four dimensional color Doppler ultrasound and the system B ultrasound have high accuracy and sensitivity in fetal congenital malformation screening,but the two detection methods have certain defects. The combined detection method can improve the accuracy of detection,and the effect is better.
