A new approach to prenatal treatment of extralobar pulmonary sequestration.

Fetal hydrothorax and hydrops is a frequent complication of extralobar pulmonary sequestration which is associated with a high perinatal mortality and severe respiratory insufficiency in the newborn. In a 27-week-old fetus with this condition, injection of 1 ml of pure alcohol and pleuro-amniotic shunting achieved resolution of hydrops. The pregnancy progressed to term and a healthy neonate was delivered who did not require postnatal surgery.
