Placental Abruption: Causes
Pronounced: pluh-SEN-tul ab-RUP-shunEn Español (Spanish Version)
Placental abruption occurs when the placenta separates from the uterus before the fetus is delivered. The placenta is the organ that provides nourishment for the fetus while it is still in the uterus. In a healthy pregnancy, the placenta remains attached to the uterine wall until after the fetus is delivered.
Some form of the condition affects about one in every 150 births. In very severe forms, placental abruption can cause death to the fetus. This occurs less commonly. Death of the mother from placental abruption is very rare.
Placental abruption can cause:
- Premature delivery
- Fetal anemia
- Low birth weight
- Significant blood loss for the mother
- Fetal death

The direct cause of placental abruption is not clearly understood. It may be a combination of several events. These may include:
- Impaired formation and structure of the placenta
- Low oxygen levels inside the uterus
- Rupture of maternal artery or vein which causes bleeding behind the placental wall
- Injury to the abdomen from an accident or a fall
- Sudden decrease in the volume of the uterus, from significant loss of amniotic fluid or from the delivery of a first twin
