[Ultrasonic diagnosis of placenta percreta. Apropos of a case with hemorrhagic complication].

Placenta percreta is a rare but severe disease, which is more and more frequent. The reported case shows that diagnosis can be made with B mode and color Doppler ultrasonography. Extension of high-vascularized placenta to the myometrium, abnormal placental-subplacental complex and vascular flow through the myometrium were suggestive of the diagnosis. Early diagnosis should decrease mortality and morbidity.
