产前超声诊断先天性食管闭锁

Prenatal ultrasound in the diagnosis of congenital esophageal atresia

目的探讨产前超声诊断先天性食管闭锁的价值。方法对22胎疑似食管闭锁的胎儿进行系统、多切面的超声扫查,包括颈部和上纵隔的冠状切面与矢状切面,详细观察食管囊袋声像图特征。结果 11胎产前超声显示食管囊袋,其中9胎产后证实为先天性食管闭锁,2胎失访;11胎未显示食管囊袋的胎儿,产后证实为正常新生儿。最早显示食管囊袋的时间为26孕周。结论产前超声对先天性食管闭锁的诊断具有重要价值,多切面扫查胎儿颈部和上纵隔,探测食管囊袋,有助于提高食管闭锁的检出率。

Objective To observe the value of prenatal ultrasound in the diagnosis of congenital esophageal atresia （EA）. Methods Systematic multiplanar ultrasonographic scanning were performed in 22 fetuses with suspected EA. Scan of the coronal plane and sagittal plane of the neck and upper mediastinum were included and image features of esophageal pouch were observed. Results Esophageal pouch was demonstrated in 11 fetuses, among which EA was confirmed in 9 fetuses after delivery, while other 2 fetuses were lost during following-up. Esophageal pouch was not demonstrated in 11 fetuses, and all were postpartum comfirmed normal neonates. The earliest gestational age of pouch visualization was 26 weeks. Conclusion Prenatal ultrasonography has important value in the diagnosis of EA. Multiple views scanning of the neck and upper mediastinum is helpful to detect esophageal pouch, which can increase the detection rate of EA.
