目的探讨产前胎儿超声检查对胎儿脐膨出的诊断价值。方法常规进行孕早中期超声结构筛查,检查时间为孕12~18周,所有超声筛查根据统一的标准进行,所有检查医生均获得早孕期NT资格认证,重点观察胎儿腹部入脐切面。结果 2011年1月至2012年12月共进行早中期筛查5640例,检出脐膨出6例,漏诊1例,是因为当时胎儿没有发生脐膨出。其中4例为单纯脐膨出,1例合并颈项部皱褶增厚,1例合并全前脑、Dandy-Walker畸形、鼻骨缺失及唇裂。结论早中期胎儿规范超声筛查可以有效地检查出脐膨出,是一种有效的筛查方法。 Objective To investigate the diagnostic value of prenatal fetal ultrasound in fetal umbilical swelling. Methods The routine screening of the ultrasound structure in the early and middle stages of pregnancy was performed. The examination time ranged from 12 to 18 weeks of gestation. All ultrasound screening was conducted according to a uniform standard. All the examiners received NT qualification in early pregnancy, with a focus on the umbilicus of the fetus abdomen. Results From January 2011 to December 2012, a total of 5640 early-mid-term screening tests were performed. Six cases of umbilical swelling were detected and one case was missed because none of the fetuses had umbilical swelling. Among them, 4 cases had simple umbilical bulging, 1 case had neck folds thickening, 1 case had combined anterior forebrain, Dandy-Walker deformity, nasal bone missing and cleft lip. Conclusion Early or mid-term fetus standard ultrasound screening can effectively detect the umbilical swelling, is an effective screening method.
