Some studies have shown a reduction in fetal growth associated with placenta previa, and the presence of the placenta in the lower part of the uterus makes breech or abnormal presentation of the fetus more likely. The bleeding of placenta previa can increase the risk for preterm premature rupture of the membranes (PPROM), leading to premature labor. Placenta accreta is a serious complication that occurs in 5% to 10% of women with placenta previa. Placenta accreta results when the placental tissue grows too deeply into the womb, attaching to the muscle layer, resulting in difficulty separating the placenta from the wall of the uterus at delivery.
