[Fetal diaphragmatic hernia. Its incidence and outcome after a 5-year period].

The reported mortality of the newborns with congenital diaphragmatic hernia is high. We retrospectively reviewed 10 cases of congenital diaphragmatic hernia (CDH), which were born in the University Maternal Hospital in Sofia for a five year period. Three of the fetuses died before birth, five died in the first 30 minutes after birth and two underwent operation for the correction of the diaphragmatic defect. Pulmonary hypoplasia is without doubt associated with CHD and is responsible for the high mortality. There is no doubt a degree of pulmonary hypoplasia precludes survival, but it is difficult to define this degree.
