The incidence of abnormal placental invasion has increased 10-fold in the past 50 years, reflecting the increased number of cesarean sections performed. Management relies on accurate early diagnosis with appropriate perioperative multidisciplinary planning to anticipate and avoid massive obstetric hemorrhage at delivery. Women at risk should plan to deliver at an institution with appropriate expertise and resources for managing this condition. We report a case of placenta increta management comprising preoperative placement of a pelvic artery balloon catheter, prophylactic balloon occlusion after delivery of the fetus, and embolization-assisted resection of the invaded uterine wall. We review incidence, methods of prenatal diagnosis, risk factors, and management of abnormally invasive placenta.
