Placenta previa
What is placenta previa, knows far fromeveryone. However, many pregnant women face this concept in the period of carrying their baby. Placental presentation is a pathology. It is due to 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 full presentation is called pathology, withThe placenta almost entirely covers the inner pharynx. Specialists also highlight the low location. The edge of the placenta is below the level, but overlapping the area of the internal throat does not occur.
The placenta presentation has several causes. Most often, inflammation 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's why this pathology is often observed in repeatedly pregnant mothers.
Placenta previa. Symptoms
A physician can identify placenta previa,the symptoms of which are, above all, recurrent bleeding, by ultrasound examination. Bleeding at the future mother at the same time arise 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 load,sexual life and various thermal procedures. In addition, cough-type movements, constipation, vaginal examinations can also contribute to bleeding. If a complete placenta previa has been identified, then it should not be surprising that bleeding occurs regularly and suddenly. Most often this process is not accompanied by any severe pain.
Generally, placenta previa can provokedelay in the development of the child due to oxygen starvation, which 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 aboutbleeding, 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, which is also characterized by blood discharge. In addition, if there is a complete presentation of the placenta for ultrasound, a similar examination of the uterus and vagina is generally not recommended.
Pregnant women with this pathology are placedin a special hospital. At the same time, the expectant mother must necessarily observe 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 of your child.
