During the period of bearing a baby, the female body undergoes numerous changes. They begin with a change in the hormonal background. Further changes occur in the genital organ itself. During this period, the woman still does not even suspect her new position. This article will focus on the term "chorion". You will learn about what it is and where this education is located. You can also get acquainted with the problems that may arise with chorion.
Conception process
To begin with, it is worth saying a few words about fertilization. In a healthy woman, a follicle rupture occurs once a month. At this moment, a female gamete comes out, ready for fertilization.
If sexual intercourse takes place at that moment, then the male cells will be able to freely meet the egg. When two gametes merge, continuous cell division and movement begins. When the formation reaches the genital organ, the fetal egg attaches. It grows tightly into the inner lining of the uterus and remains there for a long time.
Chorion - what is it?
Chorion is the outer fetal membrane of the embryo. It is worth noting that the fetal egg consists of two important components: amnion and chorion.
The outer part (chorion) is the most important part. It is she who borders the inner lining of the uterus. The localization of the chorion may be different. You will learn about the most popular of them later.
Chorion is a component of a normal pregnancy. Without it, the fetus cannot develop normally and simply perish. This membrane appears approximately one week after fertilization and remains until the formation of the placenta. Many doctors say that chorion is a placenta. To some extent, this statement is true. It is at the junction of the upper fetal membrane with the endometrium that the placenta is formed.
Chorion Diagnosis
This formation can not be determined by vaginal examination. Chorion is a formation that can only be seen with an ultrasound scan. Always in the ultrasound protocol, the specialist describes the state of this structure, its location and features.
Chorionic species
Medicine knows several varieties of the upper membrane of the ovum. It is worth noting that they all depend on the gestational age and can change greatly over time. It is possible to determine the type of chorion only with ultrasound.
Pregnancy up to 6 weeks from conception
At this stage of development of the ovum, chorion is ring-shaped. What it is?
On examination with an ultrasonic sensor, you can find a fetal egg. It is worth noting that the embryo at this time is not yet visible. The upper membrane of the ovum is attached to the endometrium over its entire area. It is in this case that it can be said that a ring-shaped chorion takes place.
Pregnancy up to 8 weeks from conception
Often, in the protocol of an ultrasound examination of a woman, a record is found: "Circular chorion." What does it mean?
A similar condition of the upper fetal membrane is characteristic of early pregnancy. This kind of education is transformed at about 8 weeks after fertilization.
Chorionic villus
This type of shell is absolutely normal. Many women ask the gynecologist: “Villous chorion: what is it?”
The shell got its name due to the fact that it has the so-called villi. It is with their help that it is attached to the inner wall of the genital organ. The villous chorion is always described in the ultrasound protocol. Its location is also noted.
Chorion localization
There are several common options for attaching this structure. Doctors still do not know why the fetal egg chooses this or that place. We will understand each of the possible options.
Back localization
This condition is the most common. In most cases, in the first trimester of pregnancy, chorion is found along 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 is not located on the back wall, then it is attached to the front of the uterus. This condition 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 instructions of a doctor, then most likely you will be able to avoid such complications. Do not panic when receiving such information. Chorion is able to move and migrate.
Lateral arrangement
Chorion during pregnancy may be on the side. This position is always reduced to the front or rear. At the same time indicate that the chorion is located, for example, in front and on the right.
Chorion Presentation
Many pregnant women have to deal with this diagnosis. First, it’s worth figuring out what “presentation” means.
If the fetal egg is attached low in the genital organ, then the resulting chorion will overlap the cervical canal or simply be located very close to the exit from the uterus. This condition is a pathology, but treatment for it has not yet been invented.
Do not be upset about this arrangement of the chorion. He can migrate. The formed placenta can also move up or sideways. So, placenta previa, which was detected during the second screening, often disappears during the third examination with an ultrasound probe.
What could the presentation of the chorion threaten?
This condition in most cases goes away on its own. However, there is a category of women in whom the chorion and placenta remain in their place and do not move anywhere. What is this fraught with?
With this outcome, doctors can choose a 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 on her own. In other cases, a planned additional ultrasound is performed several days before the birth and, if necessary, a cesarean section is prescribed.
Chorionic Presentation: Precautions
If you are given this diagnosis, the doctor will give several recommendations. It is worth taking advice and observing all safety precautions. Otherwise, spontaneous bleeding can occur, which lead to the most unexpected consequences.
Physical Rest
In the presentation of the chorion, complete physical rest is always assigned. A woman needs to give up physical education and sports exercises. Also, you can not lift heavy objects and make sudden movements.
In some cases, it is even forbidden to sneeze, since a sharp contraction of the uterus can lead to partial detachment of the chorion.
Sexual rest
In addition to physical rest, sexual is also necessary. It is worth abandoning all contacts until the chorion rises to a safe distance from the cervical canal. Otherwise, involuntary contractions of the genital organ can cause bleeding.
Medication
With a presentation of chorion, a doctor may prescribe some medications. They relax the uterine muscle and do not allow it to contract. In the early stages of pregnancy, these can be Duphaston tablets, rectal suppositories Papaverine, No-Shpa tablets. At a later stage of embryo development, other drugs may be prescribed: injections or Ginepral tablets, Magnelis B6 vitamins.
It is worth noting that taking such medications is necessary only on the recommendation of a doctor. In some cases, you can completely do without them. Also, the doctor may recommend wearing a bandage. This device will support the stomach and alleviate the general condition of a pregnant woman.
Summarizing
While waiting for the baby women undergo various studies. Including ultrasound. With such an examination, the doctor always examines the chorion and notes its localization. This takes into account the size of the shell, the presence of detachments and other problems.
When presenting chorion always follow the advice of a doctor. Only in this case, the pregnancy will end in a successful delivery.
