Placenta accreta is an abnormal adherence of placenta to the uterine wall without interposition of decidua basalis. Placenta percreta is the rarest form but may complicate the pregnancy with acute severe hemorrhage. We report a case of placenta percreta with multiple perforations of an unscarred uterus reaveled by hemoperitoneum at 22 weeks in a 33-years-old gravida 2 para 1. Emergency total hysterectomy was performed. Risk factors, clinical approach and therapeutic managements are discussed.
