摘　　要：目的:探讨标准化超声切面检查在孕早期胎儿结构畸形筛查中的应用价值。方法:选取1567例孕早期孕妇行标准化超声切面检查,观察胎儿结构畸形筛查结果,并在孕中期对胎儿进行超声复查,随访妊娠结局。结果:在孕早期诊断出胎儿异常8例(占0.51%),孕中期诊断出结构畸形3例,孕晚期检出膈疝1例,胎儿出生后检出心脏室间隔缺损1例。孕早期超声筛查胎儿结构畸形诊断灵敏度、特异度、符合率及漏诊率分别为66.67%、99.71%、99.72%及41.67%。结论:孕早期进行标准化超声切面检查,虽有助于筛查出部分胎儿结构畸形,但仍具有较高的漏诊率,故在怀孕早期、中期及晚期对胎儿进行连续动态筛查,有助于降低胎儿结构畸形的漏诊率。Objective：To investigate the value of standardized ultrasound section examination for fetal structural abnormalities trimester screening. Methods： Selected 1567 cases of trimester pregnant women as research subjects, who were performed standardized ultrasound examination section, observed the fetal malformations screening results, and used ultrasound review to fetus in the second trimester, follow-uping pregnancy outcomes. Results：Trimester diagnosis of fetal abnormalities in 8 cases（0.51%）, the second trimester diagnosed three cases of malformations, diaphragmatic hernia, one case detected in the third trimester, the fetus after birth detected one case of cardiac septal defects. trimester ultrasound screening fetal structural abnormalities diagnostic sensitivity, specificity, diagnostic accuracy, misdiagnosis rate was 66.67%, 99.71%, 99.72%, 41.67%. Conclusion：Standardization ultrasound examination section in the first trimester can help detection part of fetal structural abnormalities, but it still has a high rate of misdiagnosis, continuous dynamic screening of the fetus in early, middle and late pregnancy can reduce deformity the rate of misdiagnosis.
