| 目的 总结产前超声诊断胎儿食管闭锁的经验。方法 对2002年—2007年在我院行胎儿系统超声检查并有产后随诊结果的20例病例进行综合分析。结果 单纯食管闭锁7例;合并食管气管瘘6例;漏诊4例;误诊3例。腹围小于孕周17/20例(85.0%);羊水过多17/20例(85.0%)。3例染色体异常。结论 胃泡不显示或不确定显示、腹围小于孕周、羊水过多是胎儿食管闭锁的主要间接征象,闭锁盲端的囊袋状扩张是直接征象。 |

| Objective To summarize the experiences on antenatal sonographic diagnosis of esophageal atresia. Methods In the 5-year period from 2002 to 2007, 20 fetuses with esophageal atresia were analyzed retrospectively. Results Single esophageal atresia was found in 7 cases, combining with esophago-tracheal fistula in 6 cases, missed diagnosis in 4 cases, misdiagnosis in 3 cases. Abdominal circumference (AC) less than normal was found in 85.0% (17/20); polyhydramnios in 85.0%(17/20). Chromosomal abnormality was found in 3 cases. Conclusion Non-visualization or uncertain visualization of magenblase and abdominal circumference (AC) less than normal are the main sonographic characteristics to find esophageal atresia. Cystoid dilation of superior esophagus is the direct sign of esophageal atresia. Polyhydramnios is an important indirect sign. |
