[A case report of placenta percreta with bladder invasion].

A 33-year-old British woman who had undergone caesarean section at 31 years of age was admitted to our hospital at 28 weeks of gestation due to a large amount of genital hemorrhage induced by total placenta previa. Magnetic resonance imaging showed placenta percreta with bladder invasion. To control the sudden hemorrhage at 31 weeks of gestation, we performed an operation emergently. An occlusion ballon was inserted into the bilateral internal iliac arteries by radiologists, caesarian section followed by simple hysterectomy was performed by gynecologists, and then the bladder wall with placenta percreta was removed by urologists. Although the operation was carefully undertaken with multi-department cooperation, 11,550 ml of blood was lost during the 6.5-hour operation. There are few reports of placenta percreta with bladder invasion, about 30 cases including 3 cases in our country have been reported around the world until now.
