How should it be located?
For the correct growth and development of the baby, it is important that the placenta is properly formed. Its location is an important factor in the proper course of pregnancy.
Ideally, the placenta should be attached to the back of the uterus, at its upper end and closer to the bottom. After all, as the fetus grows, the walls of the uterus stretch very much. But not evenly, but more along the front wall. It is considerably thinner. The rear wall remains dense and less prone to stretching.
Therefore, it is natural and normal to attach the embryo to the posterior wall, because the placenta does not have stretch properties. That is, the placenta on the back wall is less susceptible to loads that burden it. This means that the attachment of the fetus to the posterior wall and the development of the placenta is ideal.
Variants of placental placement may be different: lateral fixation (right or left of the posterior wall), on the front wall of the uterus. The latter option is the most dangerous. After all, the placenta on the front wall is subject to heavy loads due to the proliferation of the uterus, the activity of the fetus and the mother. This is the risk of damage to the placenta or its premature detachment. Also, the placenta can descend close to the uterus of the uterus, or it may block the exit to the birth canal.
Causes of anterior presentation
Why is placenta previa on the anterior wall? The reasons for this have not been fully explored. One of the main ones is damage to the endometrium (inner layer of the uterus). That is, the effects of inflammation, curettage, scars from operations. The cause of placenta previa on the anterior wall may be uterine fibroids, other pathologies. By the way, in primiparous women this pathology is detected much less often than in the second, third birth. Gynecologists explain this by the condition of the inner shell of the uterus.
But the cause of this pathology can be not only mom. Sometimes the problem lies in the development of the fetal egg. Lagging development contributes to the fact that it does not have time to penetrate into the endometrium. Then implantation occurs in the lower part of the uterus.
Often a fetal egg is attached to the anterior wall of the uterus, but in its upper part. Then the placenta migrates down.
The front presentation of the placenta is diagnosed in several ways. Palpation gives different sensations in full and partial presentation. In the first case, the gynecologist feels that the uterine cry is completely blocked by the placenta. If the presentation is partial, then the doctor feels placental tissue and fetal membranes. But lateral and marginal presentation are equally perceived during examination. That is, a doctor without additional research can not determine what kind of partial presentation is involved. This research is ultrasound. Therefore, prospective mothers are strongly advised to attend all prescribed examinations and ultrasound examinations.
Treatment of pregnant women with a front presentation
The treatment process means constant monitoring and supervision of a gynecologist, timely, and sometimes additional research. In this case, not only the condition of the placenta is monitored, but also the pregnant woman. At a front presentation, blood tests are checked for hemoglobin and clotting of blood. After all, anemia or blood coagulability can be fatal for a woman in case of bleeding.
If this happens for a period longer than 24 weeks, the woman is put in a hospital. At the same time, the hospital should have a resuscitation block in case of a large loss of blood. The main purpose of such women - absolute peace. After stopping bleeding, as a rule, a woman is left in the hospital until delivery, because it must be regularly and often observed. Usually doctors successfully prolong the pregnancy even before the time when the life of the fetus can be saved.
So, if you have a front placenta previa, then you should take care of yourself as much as possible. You are obliged to protect the stomach, move gently and avoid the effects on him. Let it even be the desire of one of the relatives to pat your belly with the most good intentions. This is especially dangerous at a later date, because it can cause false, training fights.
Be healthy and calm!
