Two cases of placenta percreta diagnosed with doppler ultrasonography

We report here two cases of placenta percreata previa that occurred after repeat cesarean section, diagnosed by Doppler ultrasonography, and treated surgically. Our first case was referred to our department at 34 weeks of gestation because of placenta previa and history of cesarean section. The placenta covered internal os symmetrically. Retroplacental hypoechogenic zone of the decidua was absent, and there were placental lacunae. Power Doppler examinations revealed that placental vessels reached to uterine serosa. She was delivered by classical vertical incision cesarean section at 35 weeks of gestation, placenta was left at place after cord ligation. After two months, a hysterectomy was performed. The second case was referred to our unit at 35 weeks of gestation because of placenta previa and history of cesarean section. The ultrasound examination revealed placental lacunae and absence of hypoechogenic zone between placenta and decidua. Placenta percreta was diagnosed. At 36 weeks of gestation, a classical cesarean section was performed, and due to excessive bleeding hysterectomy was carried out at the same time. The diagnosis of placenta percreta was confirmed pathologically after surgery.
