Qualitative abnormal fetal breathing movements, associated with tracheal atresia.

A case is reported in which qualitatively, grossly abnormal fetal breathing movements turned out to be indicative of complete tracheal atresia. Fetal breathing movements were vigorous and jerky and of large amplitude; similarly abnormal movements were observed after birth. At postmortem tracheal atresia was diagnosed, in combination with other congenital abnormalities, which pointed to a VATER-association. The combination of a VATER-association with tracheal atresia has only been reported once before. An absence of the normal Hering-Breuer reflex in this case of complete tracheal atresia, probably explains the abnormal fetal breathing pattern. This case is in line with a growing number of reports in literature in which qualitatively abnormal fetal movements were indicative of congenital malformations.
