Neck of the uterus during pregnancy

Cervical neck as a diagnostic criterion of normal or pathological course of pregnancy

The cervix during pregnancy plays a very important role. Its length determines the beating or unbearable of the fetus, since pregnant women who have a short one will automatically fall into the risk group.

Extremely rarely short cervix – this is congenital pathology – an anatomical anomaly of the body development.

Often, its shortening occurs medical interventions, requiring the expansion of the cervical canal (abortions, diagnostic scraping and T.NS.). In addition, scars of various origin also deform this body and lead to its shortening. That is why it is so important to plan a pregnancy and examine the gynecologist before conception. And also to be observed all the pregnancy so that the doctor can control the neck and bottom of the uterus, as signs of the right development of pregnancy in accordance with the timing and size of the fetus.

This pathology, as well as any other, should not prevent a woman to give birth to a healthy child and, especially quietly, to carry it out, and regular observation will allow not to waste time if some problems are found, and immediately eliminate them.

Anatomy of the cervix

This body is a dense muscular ring located at the bottom of the uterus and compounding its cavity with the vagina cavity. In a non-heated woman, it has a size about 30 mm and closed zev. From the moment of conception, the size of the cervix, its condition and the degree of opening of the 13.

Changes in pregnancy

Metamorphosis of the cervix proceeds throughout the pregnancy. During this period, blood circulation in the uterus increases, which entails a cyanotic (shiny) shade of cervical. Endocervical epithelium grow up, producing a thick mucus to create a pathogenic microflor barrier.

Epithelium cervix is ​​subject to influence of estrogen changes. Since the conception of estrogens, it is initiated by hyperrophy of myometrium, as a result of which the size of the cervix, and its volume increases.

In the diagnosis of a normal or pathological course of pregnancy, the correspondence of such parameters is plays an important role as: the length of the organ characteristic of one or another period of pregnancy, the size of the uterus during pregnancy, as well as the bottom of the uterus, which is located at different heights by weeks of pregnancy.

The correspondence of these three period parameters indicates the course of pregnancy without pathologies. Inconsistency of one or two – about the presence of pathology.

If the height of the bottom of the uterus and its dimensions can vary depending on the amount of embryos and the accumulation waters, as well as the Constitution of the woman, the discrepancy in the cervix parameters indicates pathology.

From the parameter of the body length directly depends the success of toaling a pregnant child. That is why control over the neck Gynecologist throughout the pregnancy. The length of the cervix periodically measured with an ultrasound, for timely preventing miscarriage.

In early pregnancy, neck dense, ineelastic, blue in appearance. In terms of 12 to 37 weeks, it has a size of approximately 35-45 mm in length. By 38 weeks she crushes.

Before childbirth, as well as in the battle period, this organ is shortened to 10 mm and is located in the central part of the small pelvis. The maturity of the cervix and its preparation for childbirth is determined by the parameters of length, consistency and disclosure of the cervical canal.

In the process of birth, it is revealed to a diameter of 10 mm, which allows the child to go through the pelvis.

An increase in the diameter of the neck leads to ectopia – turning the endocervical epithelium into the vagina, which is considered normal during pregnancy.

Pathology

Short cervix is ​​the immediate threat to premature birth. In cases of shorting to 30 mm, it is necessary to medical monitoring of pregnant women, and sometimes surgery.

Most often, this pathology arises against the background of hormonal disorders, and is found in 16 weeks of pregnancy. In addition, evidence of the threat is not only the length of the neck, but also the diameter of its oza is more than 6 mm. In this situation, we are talking about premature births and the disclosure process has already begun, if this is an early term of pregnancy – about the threat of miscarriage.

In cases where the pregnant woman is short (up to 20 mm), the neck of the uterus, the doctors speak of the Eastic and cervical insufficiency (ICN), which must be corrected.

A reliable diagnostic method is also ultrasound of the cervix, performed during pregnancy vaginal or transabdominal sensor. Such a study helps the doctor to control the sizes of the body, as well as the cervical canal, which should be tightly closed.

Treatment with short cervical

In cases where ICH is provoked by a hormonal imbalance, a medical hormonal correction is performed.

Curry uterus and pregnancy in tandem can cause ICN, especially if a rudimentary horn was removed, and a full-fledged horn does not give sufficient space to a child. Due to severe neck pressure, a serious threat of pregnancy interruption arises. Therefore, women in such a situation are recommended to perform executable.

When a short cervix in pregnancy is provoked by no hormonal causes, surgical intervention is also carried out.

Cervical server is performed – the imposition of circular seams on the neck, restraining it in a closed state, preventing premature disclosure, the rupture of the fruit bubble and, in fact, premature labor. In some cases used non-surgic.

This is the use of various obstetric pessaries that support the neck of the uterus in a closed state, and dressed on it through the vagina.

Pregnant with a short cervix must be under the supervision of a doctor. In addition, they are forced to ensure their emotional peace (despite any stress), careful attitude, and also carefully listen to changes in their body, in order to avoid hospitalization for the entire period of pregnancy.

Tingling in the uterus

Another symptom that can declare a cervix – tingling.

The feeling of tingling as such can occur in women from the earliest time of pregnancy. This is due to the fact that the uterus is constantly growing, bundles that support it – tensioning. This creates short-term phenomena in the form of point tingling or pulling sensations that pass by themselves.

If tingling in the uterus during pregnancy, comprehensively with the discharge from the vagina (brown or bloody), lasts for a long time, and they are joined by pulling pain, then refer to the doctor or call «ambulance» – Such a process can be caused by the softening and opening of the cervix.

Of course, if pregnancy without pathologies and time after 35 weeks, then nothing to worry about. And if a period of up to 35 weeks and you know that you have a short neck, then you immediately lie down in the hospital – do not risk it nor a child.

Thus, the uterus and cervix during pregnancy undergo multiple changes. It is necessary to regularly observe the doctor, in order for these changes even in case of deviation from the norm, they did not affect the baby and the future mom. And pregnancy was allowed by normal natural clauses on time.
