[Placenta percreta and uterine rupture. Apropos of 2 cases].

The authors present two cases of uterine rupture by placenta percreta at 27 and 36 weeks of gestation. Conservative treatment was used in the first case, and radical in the second. Concerning placenta percreta, an overview is presented. The pathophysiology is unclear, but a perturbation in the equilibrium between the trophoblast and the caduque is accepted. Many factors, maternal uterine and placental, contributes to this situation. Clinical presentations are hemorrhage, uterine inversion or rupture. The disappearance of the retroplacental anechogenic zone is the recent ultrasound's contribution to the early diagnosis. The treatment is either radical which is the treatment of choice or conservative and the methotrexate could be an interested option.
