Placenta percreta: report of two cases and review of the literature.

Placenta percreta is a serious complication of pregnancy. Two cases of placenta percreta confirmed histologically were treated by supravaginal hysterectomy. Case 1: A case of uterine rupture secondary to placenta percreta was diagnosed in a 29-year-old term primigravida during an elective abdominal delivery of a healthy fetus. Spontaneous rupture of the primigravid uterus due to placenta percreta without a history of trauma or infection is a very rare occurrence. Case 2: A 33-year-old previously healthy G4P2 woman was admitted at 29 weeks of gestation with acute abdominal pain and hemorrhagic shock. There was a history of one induced abortion and two cesarean section deliveries. A review of risk factors, diagnostic tools and treatment possibilities are given.
