Placenta accreta occurs in approximately 1 in 2,500 deliveries.
Risk factors include placenta previa, Asherman’s syndrome, the existence of a prior hysterotomy scar, and advanced maternal age or parity.
Almost 50% of all cases of placenta accreta are diagnosed antepartum.
MRI combined with ultrasound has a sensitivity of 100% in identifying placenta accreta.
Medical management should be considered only when the patient wishes to preserve her fertility and when no active uterine bleeding is present.
Gravid hysterectomy has been associated with a mortality rate of 7.4%, with a 90% incidence of transfusion, a 28% incidence of postoperative infection, and a 5% incidence of ureteral injuries or fistula formation.
