Ideally, the placenta is attached closer to the bottom of the uterus along the anterior or posterior wall of the uterus. This is the normal location of the placenta. But it also happens that the attachment of the placenta is somewhat different from the norm. In this case, they speak of a low attachment, edge, full or central presentation.
The central placenta previa is a condition where the entire placenta is located in the lower part of the uterus and completely blocks the inner cervical cervix. This location of the placenta from the internal pharynx does not allow a woman to have a baby, therefore in this case they resort to a cesarean section.
The causes of abnormal attachment of the placenta
The main causes of low attachment and presentation of the placenta are changes in the inner wall of the uterus. As a result, the egg is not attached where it is provided by nature.
Most often, the changes are related to the inflammatory process in the uterus, which often occurs against abortion and scraping. Or it is associated with infections transmitted through the genital tract.
Preposition of the placenta may be due to deformities of the uterine cavity due to congenital anomalies of its development or acquired - for example, uterine fibroids . Preposition is often found in women who have heart disease, kidney and liver problems.
In re-maternal women, placenta previa is more common than in primiparous women. This is associated with acquired with age "sores", including - gynecological.
The prognosis of placenta previa is such that the position of the placenta can change by the end of pregnancy - it can rise higher. This is due to the phenomenon of "migration" of the placenta during the growth of the uterus. So, if you were diagnosed at an early age, do not despair - maybe everything will change, and you will be able to give birth naturally.
