[Prenatal diagnosis of placenta acretta by ultrasound and its histopathological association].

Background: Anomalous adhesions of the placenta, known as placenta accreta and its variants, are the cause of obstetric hemorrhages that put the pregnant woman at risk. Accretism is strongly associated with a history of uterine surgery (cesarean section, myomectomy, curettage), as well as ultrasonographic signs, such as the presence and size of placental lacunae, loss of the placenta/bladder interface, location on the anterior face of the placenta, and presence of Doppler flow; these markers can be assessed by prenatal ultrasound.

Objective: To analyze the association of prenatal diagnosis of placenta accreta by ultrasound with the histopathological result using the Tovbin index.
