Can a marginal placenta previa have a normal delivery?

Patient's question:

No.

Doctor's answer:

Generally speaking, after pregnancy, the distance from the lower margin of the placenta to the internal os of the cervix should not be less than 7 centimeters. If it is below 7 centimeters, it is considered marginal placenta previa. In such cases, if a natural delivery is attempted, it may affect the delivery process. Additionally, if the lower segment of the uterus covers the placenta, postpartum hemorrhage may occur due to poor uterine contraction after placental separation. Therefore, since your placenta is positioned relatively low, the risk in this situation is quite high. It is best to deliver via surgery to prevent adverse effects.
