Fetal therapy

Over the past 40 years, a small but increasing number of fetal genetic and congenital anomalies has become amenable to in utero treatment. Successful fetal therapies have included open procedures for congenital diaphragmatic hernia, cystadenomatoid malformation of the lung and saccrococygeal teratoma, shunts for uropathies and thoracic fluids, pharmacological therapies for congenital adrenal hyperplasia and neural tube defect prevention, and the stem cell treatment of severe combined immunodeficiency disorder.
