Multifetal pregnancy takes place in 1 of 70- 80 deliveries. The threat factors includes ovarian stimulation, assisted reproduction, advanced maternal age and prior multifetal pregnancy. Multifetal pregnancy also increases some risk factors in women such as preeclampsia, preterm delivery, growth restriction, gestational diabetes, postpartum haemorrhage and Cesarean delivery. The inflated uterus leads to encourage preterm labor thus, causes preterm delivery at gestation period of 35-36 week for twins, 32 weeks for triplets, 30 weeks for quadruplets in average. This may cause structural presentation of the fetus as abnormal. The size of the uterus may decrease after first child delivery risking the remaining fetuses by shearing away the placenta. Sometimes it leads to maternal haemorrhage and atony because of uterine distention impairs postpartum uterine contraction. It can be diagnosed by prenatal ultrasonography which act as an evident for multifetal pregnancy which is suspected if the uterus is large for dates. The only treatment to prevent fetuses is Cesarean delivery. This is mostly suggested when the fetuses are in vertex presentation.
