[Placenta praevia percreta with bladder invasion: a life-threatening pregnancy complication].

Placenta percreta is characterized by the penetration of trophoblast through the myometrium and peritoneum. This invasion may also involve adjacent structures. This condition is the most serious of placental implantation anomalies. It is a rare but life-threatening complication of pregnancy. We present a case of placenta praevia percreta with involvement of the bladder, discuss the particularities of the diagnosis and management, and review the literature.
