Which complication can arise due to placenta previa?

In cases of placenta previa, where the placenta partially or completely covers the cervix, a significant complication that can arise is hemorrhage. This occurs because as the cervix begins to efface and dilate during labor, the blood vessels within the placenta can rupture, leading to heavy bleeding. This bleeding can be dangerous for both the mother and the fetus and may require immediate medical intervention, potentially including a cesarean delivery if the bleeding is severe.

While preterm labor, fetal distress, and infection can occur during any pregnancy and in various circumstances, they are not direct complications associated specifically with placenta previa in the same way that hemorrhage is. The risk of hemorrhage from the vascular changes and position of the placenta makes managing cases of placenta previa particularly critical during pregnancy and delivery.
