Placenta previa

What is placenta praevia is not known to everyone. However, many pregnant women face this concept in the period of carrying their baby. Placenta previa is a pathology. It is associated with the fact that the placenta in this situation is located in the lower part of the uterus. It can overlap the area of the internal pharynx partially or completely. This pathology is typical for one percent of all expectant mothers. If the pregnancy is normal, the placenta is located at the bottom of the uterus, the back wall and goes to the side. This place has the best blood supply to the woman's genital organ. Placenta prevalence on the back wall in most cases is able to protect it from various kinds of accidental injuries and injuries.

A complete presentation is a pathology, in which the placenta almost completely covers the inner pharynx. Specialists also highlight the low location. In this case, the edge of the placenta is below the level, but overlapping the area of the internal throat does not occur.

Presentation of the placenta has several causes. Most often, inflammations or various surgical interventions cause the development of this pathology. Prevalence of the placenta is more common in those women whose previous births were very complicated. That is why this pathology is often observed in repeatedly pregnant mothers.

Placenta presentation. Symptoms

The doctor can identify placenta previa, the symptoms of which are considered, above all, recurring bleeding, using ultrasound examination. Bleeding at a future mother in this case occurs absolutely at any time. They may become more frequent in the second half of the period of gestation, since it is during this time that the so-called lower segment of the uterus is formed. In recent weeks, they are increasing as a result of regular contractions of the uterine muscles. It is worth noting that during the detachment of the placenta, the blood appears directly from the vessels of the uterus itself. As for the fetus, he does not lose blood. However, the baby is threatened by another - oxygen starvation, because this part of the placenta will no longer participate in the necessary child gas exchange.

A pregnant woman should limit the burden, sex life and various thermal procedures. In addition, cough-type movements, constipation, vaginal examinations can also contribute to bleeding. If a complete placenta previa was revealed, then it should not be surprising that bleeding occurs regularly and suddenly. Most often this process is not accompanied by any severe pain.

In general, placenta previa can provoke a delay in the development of the child due to oxygen starvation, of which it has already been said. Some experts associate this pathology with an incorrect presentation of the fetus, that is, oblique or pelvic. However, these events are in no way connected with each other.

If the patient seeks a doctor with complaints of bleeding, the specialist first carefully examines the cervix and the walls of the vagina. For this, the doctor uses a special mirror. This is required in order to exclude the possibility of any trauma or pathology, for which bloody discharge is also characteristic. In addition, in the case of a full presentation of the placenta on ultrasound, a similar examination of the uterus and vagina is generally not recommended.

Pregnant women with this pathology are placed in a special hospital. At the same time, the expectant mother must necessarily comply with bed rest, take the medicines prescribed to her by the attending physician. If bleeding at a later date is repeated very often, it is possible that the mother will have a cesarean section. Sometimes this method becomes the last chance to save life and health for your child.
