[Antenatal diagnosis and management of congenital chylothorax].

A case of congenital chylothorax diagnosed with prenatal ultrasonography is described. Thoracocentesis was performed at 33 weeks of gestational age but recurrence of chylothorax, increasing hydramnios and subcutaneous oedema made cesarean section necessary at 37 weeks. Mechanisms of chylothorax during the fetal life and its management before and after delivery are discussed.
