To determine the biologic significance of a transient anechoic area observed in the midline of the fetal neck when attempting an antenatal ultrasound diagnosis of congenital esophageal atresia (CEA), a prospective study was made in 10 cases presenting both polyhydramnios and an unusually small stomach size due to a decrease in fetal stomach fluid. There were 8 cases indicating a transient anechoic area in the fetal neck, all of which were diagnosed as having CEA postnatally by plain roentgenogram, neonatal surgery, or autopsy findings. The remaining 2 cases had no CEA; one had Nager's syndrome and the other, a disorder involving neuronal migration in the central nervous system. These results suggest that an anechoic area in the middle of the fetal neck can be used as an indication of CEA and also for differentiating this condition from diseases with possible swallowing impairment.
为确定在尝试产前超声诊断先天性食管闭锁（CEA）时，胎儿颈部中线处观察到的短暂无回声区的生物学意义，对10例因胎儿胃内液体减少而出现羊水过多和胃尺寸异常小的病例进行了一项前瞻性研究。有8例胎儿颈部出现短暂无回声区，所有这些病例在出生后经X线平片、新生儿手术或尸检结果诊断为CEA。其余2例没有CEA；1例患有纳格尔综合征，另1例患有涉及中枢神经系统神经元迁移的疾病。这些结果表明，胎儿颈部中间的无回声区可作为CEA的一个指标，也可用于将这种情况与可能存在吞咽障碍的疾病相鉴别。
