At what gestational age is cesarean delivery recommended for placenta previa?

Cesarean delivery is typically recommended for women with placenta previa between 36 0/7 and 37 6/7 weeks of gestation due to the increased risk of hemorrhage associated with this condition as the pregnancy progresses. By this gestational age range, the fetus is likely sufficiently developed for delivery while minimizing complications for both the mother and the baby.

Scheduling the cesarean at this time allows for planning and preparation, reducing the chances of an unexpected emergency situation that could arise with the onset of labor or bleeding if the placenta remains positioned over the cervix. Delivering before 36 weeks may increase the risk of neonatal complications due to prematurity. Conversely, waiting until after 37 weeks might expose the mother to greater risks if there are no medical indications for delaying delivery.

In summary, the timing of cesarean delivery for placenta previa is aimed at balancing the risks of maternal hemorrhage and ensuring adequate fetal maturity, which is why the range of 36 0/7 - 37 6/7 weeks is considered optimal.
