What to Do About Placenta Accreta After Cesarean Delivery—Can It Be Treated Successfully?

Placenta accreta spectrum (PAS) is a serious obstetric complication that occurs when the placenta attaches too deeply into the uterine wall—ranging from abnormal adherence (placenta accreta), partial invasion into the myometrium (placenta increta), to full penetration through the uterine serosa and potentially into adjacent organs (placenta percreta). When diagnosed prenatally—often via targeted ultrasound with Doppler and confirmed by MRI—management centers on multidisciplinary planning, timing of delivery, and surgical strategy. Cesarean delivery remains the standard route of birth for suspected or confirmed PAS, as vaginal delivery carries unacceptably high risks of catastrophic hemorrhage, uterine rupture, and maternal mortality.

Treatment is not defined by “cure” in the traditional sense, but rather by safe, individualized management aimed at preserving maternal life and, when feasible, fertility. In most cases, especially with placenta increta or percreta, hysterectomy performed immediately after cesarean delivery is the recommended intervention to prevent life-threatening postpartum hemorrhage. However, for select patients—such as those with limited placental involvement, strong desire for future fertility, and access to a highly specialized center—conservative management may be considered. This includes leaving the placenta in situ postpartum, administering methotrexate (though evidence supporting its efficacy remains limited), and close surveillance with serial β-hCG monitoring and imaging.

Outcomes depend heavily on early diagnosis, institutional preparedness, and team expertise. Centers with dedicated maternal-fetal medicine, interventional radiology, gynecologic oncology, and transfusion medicine support report significantly lower morbidity and mortality. Delayed or missed diagnosis substantially increases the risk of emergency hysterectomy, massive transfusion, intensive care admission, and long-term complications such as pelvic organ injury or thromboembolism.

While PAS cannot be “cured” medically before delivery, it can be effectively managed—and often prevented from becoming fatal—through rigorous prenatal screening, timely referral to tertiary care, and coordinated, protocol-driven intervention. Patient counseling should emphasize shared decision-making, realistic expectations about fertility preservation, and the critical importance of delivering at a facility equipped to handle complex placental disorders.
