Placenta accreta is a serious pregnancy condition that occurs when blood vessels and other parts of the placenta grow too deeply into the uterine wall.
Typically, the placenta detaches from the uterine wall after childbirth. With placenta accreta, part or all of the placenta remains firmly attached. This can cause severe blood loss after delivery.
It's also possible for the placenta to invade the muscles of the uterus (placenta increta) or grow through the uterine wall (placenta percreta).
Placenta accreta is considered a high-risk pregnancy complication. If placenta accreta is suspected during pregnancy, you'll likely need an early C-section delivery followed by the surgical removal of your uterus (hysterectomy).
