Question: 1 / 400

What percentage of women with placenta previa is at risk for placenta accreta?

2-5%

5-10%

Women diagnosed with placenta previa are at an increased risk for placenta accreta, a complication characterized by an abnormal attachment of the placenta to the uterine wall. Research indicates that between 5% to 10% of women with placenta previa may develop placenta accreta. This risk is particularly elevated among those who have had previous cesarean deliveries or uterine surgery, as these factors can contribute to alterations in the uterine wall that predispose to abnormal placentation.

When considering the context of maternal-fetal medicine, understanding these statistics is crucial for risk assessment and management. Knowing that a significant portion of women with placenta previa are at risk of placenta accreta allows healthcare providers to implement appropriate monitoring and planning for delivery to optimize maternal and neonatal outcomes.
