Chorioamniotic membrane separation and preterm premature rupture of membranes complicating in utero myelomeningocele repair

摘要

BACKGROUND: Since the results of the Management of Myelomeningocele Study were published, maternal-fetal surgery for the in utero treatment of spina bifida has become accepted as a standard of care alternative. Despite promise with fetal management of myelomeningocele repair, there are significant complications to consider. Chorioamniotic membrane separation and preterm premature rupture of membranes are known complications of invasive fetal procedures. Despite their relative frequency associated with fetal procedures, few data exist regarding risk factors that may be attributed to their occurrence or the natural history of pregnancies that are affected with chorionic membrane separation or preterm premature rupture of membranes related to the procedure.
