Placental Abruption
Pronounced: pluh-SEN-tul ab-RUP-shun
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 in approximately one in every 500-750 deliveries. Death of the mother from placental abruption is very rare. Infants who survive a birth with the condition have a 40%-50% chance of experiencing complications.
Placental abruption can cause:
- Premature delivery
- Fetal anemia
- Low birth weight
- Significant blood loss for the mother
Placental Abruption
The cause of placental abruption is often difficult to diagnose. Some common causes of the condition include:
- 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
- Abnormally short umbilical cord
- Acute development of high blood pressure (often associated with cocaine use)
