Placenta Previa Treatment

The position of the mothering cake determines whether a spontaneous birth is possible – a misplacement of the placenta occurs not so rare: The placenta previa occurs in about one in 200 pregnancies and often requires a cesarean section. Learn here how a placenta praevia develops, how you notice it, which risk factors favor a malposition and how it affects your childbirth.

What is a placenta previa?

Placenta previa refers to malposition of the mothering cake in the uterus. Instead of adhering to the uterus either at the top or the side, the placenta is located in the lower part and wholly or partially covers the cervix. Spontaneous birth is not possible because the birth canal is blocked. The result: The baby must be delivered with a cesarean section.

The cause of a placenta previa: The fertilized egg cell has migrated too far down and has taken root in the “wrong” place. Several risk factors favor placenta previa. These include, for example, retired women over the age of 35, previous surgery on the uterus, cesarean sections, a fast pregnancy, multiple pregnancies and miscarriage after a miscarriage. Also, smoking is suspected of favoring a misplacement of the placenta. With every subsequent pregnancy, the risk of a renewed placenta previa is around 4 to 8 percent.

However, if your doctor diagnosed misplacement of the placenta during the first half of your pregnancy, it is not a cause for concern. Placenta praevia is not discussed until after the 24th week of pregnancy, as the placenta is still elevated, away from the cervix. Can hike. However, if you have any bleeding, you should see your doctor or go to the hospital immediately.

The four forms of a placenta praevia

Depending on the location of the placenta, a distinction is made between four different forms of placenta praevia. The position of the mothering cake is decisive for the course of childbirth: is natural childbirth possible or does it have to be delivered with a cesarean section?

  • Deep placenta: The placenta is located in the lower part of the uterus but does not touch the cervix. A spontaneous birth is possible in principle.
  • Placenta praevia marginalis: The placenta is close to the cervix, but does not obscure it. A spontaneous birth is possible.
  • Placenta previa parties: The placenta partially obscures the cervix. A cesarean section is necessary.
  • Placenta previa total: The placenta completely covers the cervix. A cesarean section is necessary.

Symptoms: This is how a misplacement of the placenta becomes noticeable

First signs of a placenta preavia are frequent bleeding in the last third of the pregnancy, which occur continuously or come back again and again. You feel no pain and the stomach feels soft. Another possibility is that you notice nothing of the sickness of the mothering cake.

At the latest at the check-up in the 28th week of pregnancy, the doctor will determine whether a displacement of the placenta is present. There is still enough time to plan the exact course of the birth, without endangering the child.

However, if misplacement of the placenta is not recognized in a pregnant woman, placental detachment may rarely occur, which can be life-threatening for both mother and child.

The procedure for a placenta previa

If you’ve been diagnosed with sickness, that’s no cause for concern: your baby will still be well cared for through the placenta. If no bleeding has occurred in the last trimester of pregnancy, the attending physician will usually advise you to rest, not stress, and not exert any physical effort. You should also refrain from sexual intercourse in case of misplacement of the placenta.

If bleeding occurs, pregnant women are admitted to the hospital for inpatient control. If the bleeding persists despite bed rest, depending on the week of pregnancy and the unborn child’s lung maturity, it is decided whether it should be brought with an emergency cesarean section.
