The optimal method for antenatal treatment of pleural effusions from c
ongenital chylothorax is unknown. A fetus with bilateral congenital ch
ylothorax and hydrops had a pleural catheter placed in utero on only o
ne side of the fetal chest for 14 days prior to delivery. The fetal hy
drops partially resolved. After birth there was significantly less dra
inage from the pleural space that had been antenatally drained. This c
ase demonstrates potential neonatal advantages of pleuro-amniotic shun
t placement.
