PLACENTAL abruption (
abruptio placentae) is a pregnancy complication that happens when the placenta separates from the uterus before delivery. The placenta is a temporary organ that connects a growing foetus to your uterus during pregnancy. It attaches to the wall of the uterus, usually on the top or side, and acts as a lifeline that gives nutrients and oxygen to the foetus through the umbilical cord. The placenta also removes waste from the foetus's blood.
In placental abruption, the placenta may completely or partially detach. This can decrease the amount of oxygen and nutrients the foetus gets. It can also cause heavy bleeding in the birthing parent. Your healthcare provider will need to monitor you closely and determine if an early delivery is necessary.
Types of
placental abruption
The classification of placental abruption can be based on how much the placenta detaches from the uterus:
A partial placental abruption occurs when the placenta doesn't completely detach from the uterine wall.
A complete or total placental abruption occurs when the placenta completely detaches from the uterine wall. There's usually more vaginal bleeding with a complete abruption.
It can further be classified by how much bleeding occurs:
Revealed placental abruptions have moderate to severe vaginal bleeding that you can see.
Concealed placental abruptions have little or no visible vaginal bleeding. Blood is trapped between the placenta and uterine wall.
Placental abruption occurs in about one out of 100 pregnancies (one per cent). It most commonly occurs later in the third trimester, which begins around 28 weeks of pregnancy and lasts until delivery (around 40 weeks), but it can occur any time after 20 weeks.
Symptoms
Each patient can have different symptoms of placental abruption. But the most common symptom is vaginal bleeding with cramping during the third trimester of pregnancy.
Other symptoms include: abdominal pain, uterine contractions that are longer and more intense than typical labour contractions, uterine tenderness, backache or back pain, feeling the foetus move less.
Vaginal bleeding can vary and is not an indication of how severe the abruption is. In some instances, there could be no visible bleeding because the blood is trapped between the placenta and the uterine wall. Pain can range from mild cramping to strong contractions that come on suddenly.
Most of the time you will see some blood during a placental abruption. But if the abruption is concealed, the blood will be trapped behind the placenta. In that case, there will be no bleeding. In other cases, the abruption develops slowly, which can cause occasional, light bleeding.
Causes of
placental abruption
The cause of placental abruption is often unknown. But there are factors that increase your risk for an abruption. For example, abdominal trauma, such as from a fall or accident, can increase your risk for placental abruption, a blow to your belly (such as in a car accident or fall
