What is the treatment for placenta accreta?

Surgery: Placental accretas are difficult surgeries. Infant delivery is usually not the problem, hysterectomy is. A well-qualified ob/gyn will ensure correct surgical personnel, ample blood products, clotting agents, ureteral stents, and embolization catheters are available for delivery. Even in the best of hands, these surgeries require large blood transfusions and are considered high risk.

Tough situation: Placenta accreta occurs when the placenta, instead of forming a nice distinct plane from which it can readily separate from the uterine wall, grows into the muscle of the uterus a bit. It typically is not found until delivery. It often leads to uncontrolled bleeding, treated by surgical suturing, hysterectomy, pressure against the bleeding area, possibly with a balloon, or arterial embolization.

Prelabor c-hyst @34w: The optimal management of placenta previa with suspected accreta/increta/percreta is prelabor cesarean section by 34-35 weeks after Betamethasone administration without amniocentesis for fetal lung maturity; this should be immediately followed by puerperal hysterectomy with the expert help from a gynecologic oncologist, urologist, [vascular] surgeon. Do not attempt to detach the placenta!
