Also known as:
Placenta Abruptio, abruptio placenta
Placenta abruptio is a problem with the placenta during pregnancy. The placenta is a round, flat organ that forms during pregnancy to give the baby food and oxygen from the mother. During a normal pregnancy, the placenta stays firmly attached to the inside wall of the uterus until the baby has been born. But with placenta abruptio, the placenta breaks away, or abrupts, from the wall of the uterus too early, before the baby is born.
