Prenatal diagnosis of congenital diaphragmatic hernia not amenable to prenatal or neonatal repair: Brachmann-de Lange syndrome.
Brachmann-de Lange syndrome (BDLS) is a variable multiple congenital anomaly syndrome that occasionally includes congenital diaphragmatic hernia (CDH). CDH per se is commonly diagnosed antenatally and has been corrected with increasing success in utero and by neonatal repair with extracorporeal membrane oxygenation (ECMO). In utero repair requires normal karyotype as well as the absence of other lethal anomalies. Postnatal repair in combination with ECMO has resulted in improved neonatal outcome and has been recommended in all cases not having in utero repair. We describe a fetus diagnosed with a diaphragmatic hernia at 18 weeks of gestation in a woman whose only other pregnancy has been a 16 week abortus diagnosed with Fryns syndrome (FS). FS is a lethal, variable congenital anomaly syndrome that includes CDH, which is thought to contribute to the lethality of the syndrome. In utero repair was considered, but rejected because of the position of the liver and suspected FS. The patient elected to carry the pregnancy to term. Postnatal repair with ECMO was considered; however, the infant died at several hours of age because of severe pulmonary hypoplasia, being considered ineligible for ECMO. The diagnosis of BDLS was made at autopsy and suggests that the first case may, in fact, have been BDLS. In spite of recent success in the repair of CDH both in et ex utero, CDH in association with BDLS is likely lethal, and women with fetuses diagnosed antenatally with CDH and BDLS should be counseled as such.[1]References
