Placenta percreta, the rarest and most severe form of placenta accreta, is an extremely rare but potentially lethal event during pregnancy. Because of its propensity for severe hemorrhage, it is a potentially life-threatening condition. The pathophysiological defect in placenta accreta is a partial or complete absence of decidua basalis Placenta percreta usually presents as postpartum hemorrhage when the placenta is manually extracted from the underlying myometrium. Risk factors include previous cesarean section; uterine curettage; placental abnormalities, placenta previa; congenital anomalies; and cornual implantation of placenta. Although commonly discovered at the time of delivery, antenatal diagnosis may be achieved with ultrasound, magnetic resonance imaging.
