Antenatal diagnosis of oesophageal atresia with tracheoesophageal fistula with upper neck pouch sign-A radiological study

Abstract

Oesophageal atresia is rare antenatal diagnosis due to absence of clinical and sonographic findings. On antenatal USG, the finding of an absent or small stomach bubble with polyhydramnios is considered suspicious of oesophageal atresia. However, these findings is not confirmative. The upper neck pouch sign is another specific sign that helps in the antenatal diagnosis of oesophageal atresia.
