Patients with a history of two or more cesarean sections have a significantly increased risk of developing placenta accreta, primarily due to the changes in the uterine lining and structure that occur after multiple surgical interventions. When a cesarean section is performed, the surgical incision through the uterus can disrupt the normal implantation site and blood supply, leading to scarring (adhesions) and changes in the uterine tissue.

These conditions may predispose the placenta to implant abnormally in subsequent pregnancies, leading to a condition known as placenta accreta, where the placenta attaches too deeply into the uterine wall. The likelihood of this complication increases with each successive cesarean delivery. Studies indicate that for patients who have had two or more cesareans, the rates of placenta accreta can indeed rise above 50%, reflecting the cumulative risk associated with multiple surgeries. Therefore, identifying this population is critical for prenatal management and planning for potential complications during delivery. This understanding underscores the importance of careful monitoring and consideration for planned deliveries in these individuals to mitigate risks.
