The chorion is ... The localization of the chorion. Presentation of the chorion

During the period of gestation, the female body undergoes numerous changes. They begin with a change in the hormonal background. Then the changes occur in the most genital organ. During this period the woman still does not even suspect about her new position. In this article we will talk about the term "chorion". You will learn about what it is and where the education is located. Also you can get acquainted with the problems that can arise with the chorion.

The process of conception

To begin with it is necessary to say a few words about fertilization. A healthy woman breaks the follicle once a month. At this point, the female gamete comes out, ready for fertilization.

If at that moment the sexual act takes place, the male cells will be able to freely meet with the egg. When the two gametes merge, continuous division and movement of the cells begins. When the formation reaches the genital organ, the fetal egg is attached. It densely grows into the inner shell of the uterus and remains there for a long time.

Chorion is what?

Chorion is the outer fetal envelope of the embryo. It should be noted that the fetal egg consists of two important components: the amnion and the chorion.

The outer part (chorion) is the most important part. It is bordered by the inner shell of the uterus. The localization of the chorion can be different. You will learn more about the most popular ones.

Chorion is a component of normal pregnancy. Without it, the fruit can not develop normally and will simply perish. Appears this shell about one week after fertilization and remains until the formation of the placenta. Many doctors say that the chorion is the placenta. To some extent this statement is true. It is at the junction of the upper shell of the fetus with the endometrium that the placenta is formed.

Diagnosis of the chorion

This formation can not be determined by vaginal examination. Chorion is an education that can be seen only with ultrasound examination. Always in the protocol of ultrasound the specialist describes the state of the given structure, its location and features.

Types of chorion

Medicine knows several varieties of the upper shell of the fetal egg. It is worth noting that they all depend on the gestational age and can vary greatly over time. The type of chorion can be determined only by ultrasound examination.

The gestation period is up to 6 weeks from conception

At this stage of development of the fetal egg, a chorion can be seen ring-shaped. What it is?

On examination with an ultrasound transducer , a fetal egg can be found. It is worth noting that the embryo at this time is not yet visible. The upper membrane of the fetal egg is attached to the endometrium throughout its area. It is in this case that it can be said that there is a ring-shaped chorion.

The gestation period is up to 8 weeks from conception

Often in the protocol of ultrasound examination, women are found to record: "Circulatory chorion". What does it mean?

A similar condition of the upper fetal membrane is characteristic of early pregnancy. This kind of education is transformed about 8 weeks from the moment of fertilization.

Inoculated chorion

This kind of shell is absolutely normal. Many women ask the gynecologist: "The nasal chorion: what is it?"

The shell received its name because it has so-called villi. It is with their help that it is attached to the inner wall of the genital organ. The nasal chorion is always described in the protocol of ultrasound. It also marks the location of its location.

Localization of the chorion

There are several common options for attaching this structure. Doctors still do not know why a fetal egg chooses a particular place. We'll figure it out in every possible way.

Rear location

This state is the most common. In most cases, in the first trimester of pregnancy, a chorion is found on the posterior wall of the genital organ. In this case, it is necessary to take into account the structural features of this shell.

Front location

If your chorion on the back wall is not located, then it is attached to the front of the uterus. This state is also the norm, but special care must be taken.

With anterior localization, there is a risk of detachment of the fetal membranes. If you follow all the doctor's instructions, you will most likely avoid such complications. Do not panic when you receive this information. Chorion is able to move and migrate.

Lateral location

Chorion during pregnancy can be on the side. This position is always reduced to the front or rear. This indicates that the chorion is located, for example, in front and on the right.

Presentation of the chorion

Many pregnant women have to face this diagnosis. To begin with it is necessary to find out what "presentation" means.

If the fetal egg is attached low in the genital organ, the resulting chorion will overlap the cervical canal or simply be placed very close to the exit from the uterus. This condition is pathology, but treatment for it has not yet been invented.

Do not get upset because of this arrangement of the chorion. He can migrate. The resulting placenta can also move up or sideways. So, placenta previa, which was revealed during the second screening, often disappears during the third examination by an ultrasound transducer.

What can be threatened with a presentation of the chorion?

This state in most cases passes independently. However, there is a category of women whose chorion and placenta remain in their place and do not move anywhere. Than it is fraught?

With this outcome, medics can choose non-standard delivery. If the placenta completely blocks the entrance to the uterus, then a planned cesarean section is performed . In the case when the chorion (placenta) is located low, the doctor takes into account the distance between the cervical canal and the edge of the membrane. If the gap between the cervix and the placenta is more than five centimeters, then the woman is allowed to give birth alone. In the remaining cases, a planned additional ultrasound is performed several days before the birth and, if necessary, a cesarean section is prescribed.

Preposition of the chorion: precautionary measures

If you are diagnosed, the doctor will give several recommendations. It is worth to listen to advice and observe all precautions. Otherwise, spontaneous bleeding may occur, which lead to the most unexpected consequences.

Respect for physical rest

At the presentation of the chorion, complete physical rest is always prescribed. A woman should abandon physical education and sports exercises. Also, you can not lift heavy objects and make sudden movements.

In some cases, even it is forbidden to sneeze, as a sharp contraction of the uterus can lead to partial detachment of the chorion.

Sexual rest

In addition to physical rest, sexual intercourse is also necessary. It is necessary to abandon all contacts until the chorion rises to a safe distance from the cervical canal. Otherwise, involuntary contractions of the genital organ can cause bleeding.

Reception of medicines

With the presentation of the chorion, the doctor may prescribe some medications. They relax the uterine muscle and do not allow it to contract. In the early stages of pregnancy, it can be tablets "Dyufaston", suppositories rectal "Papaverin", tablets "No-Shpa". At a later date of embryo development, other means may be prescribed: injections or tablets "Ginepral", vitamins "Magnelis B6".

It is worth noting that it is necessary to take such medications solely on the advice of a doctor. In some cases, you can do without them at all. Also the doctor can recommend wearing a bandage. This device will support the stomach and facilitate the overall condition of the pregnant woman.

Summarizing

While the baby is waiting for the woman, various studies are under way. Including ultrasound. With such a survey, the doctor always examines the chorion and marks its localization. This takes into account the size of the shell, the presence of layers and other problems.

When chorion presentation, always follow the doctor's advice. Only in this case the pregnancy will end with a successful delivery.
