[Tracheal atresia--a special association with esophageal atresia and hydramnion]

This case report describes the prenatal diagnosis of an oesophageal atresia with the previously unpublished associated malformation of tracheal atresia. The knowledge of associated malformations or deformations in prenatally diagnosed oesophageal atresia can considerably improve the prognosis by an optimised post partum care of the newborn. Tracheal atresia can at present not be diagnosed prenatally; the possibility to identify it remains an isolated case and must therefore be taken into consideration whenever an oesophageal atresia is observed.
