Electronic poster abstractsroom where hysteroscopic uterine septum resection and placenta removal was undertaken.First, the uterine suptum was resected to the fundus level, and then the placental tissue was removed (figures 3-4).The patient was discharged home the next day and had an unremarkable postoperative course.In conclusion, retained placenta accreta represents a rare, but serious cause of postpartum hemorrhage.Prior diagnosis options for this condition have included MRI or three-dimensional ultrasound.3D ultrasonography is a new technology that can produce results as accurate and fast as MRI in diagnosing uterine anomaly or Retained Placenta accreta which potentially offers a safer means of addressing this challenging obstetrical complication.
