Placental evaluation (location, depth of invasion)

If you have had prior uterine surgeries (myomectomy, cesarean section, operative hysteroscopy, dilation and curettage, etc) it is possible that the placenta can invade deeper into the uterine muscle than normal (instead of just the inner uterine surface or mucosa). Fortunately, this is a relatively rare occurrence. It would be important to let your physician know if you had any prior uterine procedures.
