The only alternative to a cesarean section is a vaginal delivery, which can be done with the help of either forceps or vacuum, if necessary. With your condition, there are risks no matter how your baby is delivered. Let's discuss the risks of having a vaginal delivery.
When there are problems with your placenta, such as placenta previa, or placental abruption, a cesarean delivery may be considered safer than a vaginal delivery. With partial placenta previa, the placenta may migrate away from the cervix as the pregnancy progresses. If this happens in your case, a vaginal delivery may be possible. A vaginal delivery may also be possible in women who have placental abruption, if the placenta stops bleeding and separating from the uterine wall.
When these conditions do not correct themselves prior to labor, there is a higher risk of placental problems during labor and delivery. This may cause serious bleeding that can be fatal for the mother and/or the baby. Or the baby may become deprived of oxygen, which can cause temporary or permanent brain damage. In some cases, a hysterectomy may be required to stop the bleeding.
So the decision to have or not have a c-section rests with you, but it is very important for you to discuss your risks and your situation with your doctor when making this decision.
