Chorionic Villus Sampling (Cvs)

Chorionic Villus Sampling (CVS)

Chorionic Villi Testing (CVS) is a prenatal diagnostic method that can detect various genetic diseases in the fetus. This method is carried out between the eighth and eleventh weeks of pregnancy and is based on the study of chorionic villi.

Chorionic villi are small projections that form on the surface of the placenta and contain the genetic material of the fetus. It is from these villi that a sample is taken for examination.

There are two ways to take chorionic villus samples: through the cervix or through the abdominal wall. In the first case, a sample is taken using a thin needle that is inserted through the cervix under ultrasound guidance. In the second case, the sample is taken using a thin needle that is inserted through the abdominal wall. Both methods are relatively safe for the mother and fetus.

The obtained samples of chorionic villi are subjected to chromosomal and biochemical analysis to identify any abnormalities in the development of the fetus. Chromosome analysis can reveal the presence or absence of extra chromosomes, which can lead to diseases such as Down syndrome. Biochemical analysis can reveal the presence or absence of certain proteins that may indicate the presence of other diseases such as thalassemia.

One of the main advantages of the Chorionic Villi examination is the possibility of early diagnosis of genetic diseases in the fetus, which allows parents to make more informed decisions regarding the further development of pregnancy. However, it is necessary to understand that any medical procedure is not without risks, and Chorionic Villi examination is no exception. Some of the possible complications may include bleeding, infection and premature birth.

In general, examination of Chorionic Villi is an effective method for diagnosing genetic diseases in the fetus. However, as with any medical procedure, all possible risks and benefits must be carefully weighed before undergoing it. It is important that parents-to-be discuss this issue with their doctor and make a decision based on their individual circumstances and needs.



Chorionic villus sampling is a method of examining the condition of the fetus in early pregnancy, which is carried out between 8 and 11 weeks. This method is based on the study of cells that are found on chorionic villi - small outgrowths of the placenta that are attached to the wall of the uterus.

The CVS procedure works as follows: a needle is inserted through the cervix or abdominal wall, which penetrates the chorionic villi. Cells from the villi are then removed for analysis. This test includes chromosomal and biochemical analysis to detect possible fetal abnormalities such as Down syndrome or thalassemia.



Chorionic villus sampling (CVS or CVS) is an invasive procedure used to obtain cell samples from the chorionic villus and placenta during second trimester screening to determine the presence of chromosomal abnormalities in the fetus before birth.

The essence of the examination is that after passing a certain test, the patient is given a choice: agree to undergo amniocentesis or choose cvs. Some women think that chvs is less invasive than amniocentosis. However, it is not. In both cases, the pregnant woman is given a pregnancy test. You are given dimercaprol 2-3 times over one week. Then amnicitis is given for insertion into the vagina.
