Antenatal diagnosis and palliative treatment of nonimmune hydrops fetalis secondary to pulmonary extralobar sequestration.
The causes of nonimmune hydrops fetalis are multiple. Despite the fact that many of the affected fetuses are otherwise free of fatal abnormalities, many die in the neonatal period from pulmonary hypoplasia. The overall perinatal mortality is as high as 80%. Extralobar pulmonary sequestration is an abnormal and nonaerated mass of extra pulmonary-located lung tissue supplied by a systemic artery, and is a rare cause of nonimmune hydrops. In the only two published reports, the hydropic fetuses died at birth. Both the first antenatal diagnosis of this disorder and the first attempt at palliative in utero therapy are reported herein. Though the fetus ultimately delivered prematurely and succumbed, treatment was associated with both subjective improvements in fetal well-being and objective reversal of the hydrops.
