Cesarean delivery and its impact on the anomalous infant

Although cesarean deliveries frequently are performed for anomalous fetal conditions, available data do not always support a fetal benefit from this delivery management. The literature on cesarean delivery for anomalous infants reports insufficient information on comorbid neonatal conditions, so these complications are unknown in this population of newborns. In a minority of cases, a cesarean delivery is reasonable to prevent dystocia or optimize outcome. Areas for future investigation include prospective, randomized, controlled trials of prelabor cesarean compared with vaginal deliveries for myelomeningocele and anterior abdominal wall defects. The rarity of other lesions likely precludes randomized controlled trials.
