Neonatal pulmonary hypoplasia after prolonged leakage of amniotic fluid.

Abstract

The clinical, radiological, and pathological features of the 'oligohydramnios tetrad' (Potter's facies, limb malpositions, pulmonary hypoplasia, and growth retardation) resulting from chronic amniotic fluid leakage are described in 2 infants who died of respiratory failure within 12 hours of delivery. A third infant with a partial form of the syndrome had prolonged respiratory symptoms and survived the neonatal period: the course of the disease and the radiological findings were compatible with a hypothetical diagnosis of partial pulmonary hypoplasia. Pulmonary hypoplasia should be recognized as a cause of chronic respiratory symptoms in viable infants.
