Placenta percreta: report of a case.

Placenta accreta, increta, or percreta are rare but potentially lethal obstetric emergencies. Removal of abnormal growth of the placenta into the uterine wall is difficult or impossible and results in massive blood loss. Hysterectomy may be necessary to save the mother's life. The common predisposing factors in development of placenta percreta are repeat cesarean and placenta previa. The diagnosis of placenta percreta may remain undiagnosed until delivery. The case presented describes a scenario involving placenta percreta with bladder involvement in which the diagnosis was known in advance. The article describes the preoperative preparation, intraoperative events, and postoperative status of this particular case.
