Abstract
A case of placenta previa accreta was diagnosed at 28 weeks' gestation with use of power amplitude ultrasonic angiography, which showed an unusually intense blood flow within the placental sonolucent spaces and hypervascularity within the placental and surrounding tissues. High-velocity (> or = 15 cm/sec) turbulent venous-type flow was detected within the placental blood lakes, and prominent low-impedance (resistance index 0.24) arterial blood flow was detected within the uterine serosa-posterior bladder wall boundary zone. An uneventful cesarean hysterectomy was performed at 32 weeks' gestation, and histopathologic examination revealed placenta previa increta.
