Monoamniotic twin pregnancies are relatively rare, but perinatal mortality is high about 30-70%. The major cause of fetal death is cord accident, congenital anomalies, twin-twin transfusion syndrome, and intrauterine growth restriction. Especially cord entanglement occurs; perinatal mortality is about 50%. So the active management of monoamniotic twins to reduce the complication of cord entanglement is important. This is a case of monoamniotic twin pregnancy with cord entanglement and both fetuses survival by elective cesarean section at 32+4 weeks after medical amnioreduction and intensive fetal surveillance.
