Down syndrome during pregnancy, how to determine

Down syndrome is a common pathology that appears in the fetus even during the fusion of the egg and spermatozoa. As a result, during the division of the cell, an excess chromosome is formed, thus, in a sick child of them 47 instead of 46. Not every woman is ready to bring up a sick child and take care of it all his life, so it is necessary to take screenings on all stages in all the stages of pregnancy. Thus, it will be possible to diagnose the disease of the fetus in the early deadlines.

There are invasive and non-invasive methods for determining the presence of Down syndrome. Previously, the WWIS is held - on July 11-12. During this period, it is possible only by indirect features to assume the presence of this syndrome. The sonologist is measuring the size of the collar space and the thickness of the nose bone. The fetus with the pathology of the nasal bone of smaller or is missing. If the doctor suggested the presence of Down syndrome in another unborn child, do not worry. This is not a 100% probability of the presence of a disease, only invasive methods give a very accurate result.

If, according to the results of the ultrasound, the thickness of the collar space exceeds 3 mm, or there is a thin nasal bone, a woman is sent to genetics. He will give detailed advice and will write directions to additional research.

Between the 16th and 18 weeks of pregnancy, the woman should pass the blood test on HCG and AFP. By the number of these hormones, it is possible to determine the state of the fetus and assume the presence of pathologies. AFP hormone stands out in the amniotic fluid of the fetal liver. If this substance is not enough, then it can be assumed that the fetus of Down syndrome. Remember, if you are more than 35 years old, the risk of developing any pathologies in the future kid is increasing. This is due to the formation of a large number of defective eggs and spermatozoa.

If on the first ultrasound and according to the results of screening on the 16-18 week, the doctor talks about the possibility of a child's illness, it is worth agreed to check the amniotic fluid. During this procedure, the needle is introduced through the abdominal cavity of the mother, with which the liquid is taken. After 2-3 weeks you will receive an answer.

After the procedure, the risk of miscarriage and premature birth increases. No one can force a woman to take this analysis, ultimately the solution is accepted independently. Another 12 week is to analyze the chorion villion, but this diagnostic method is very dangerous than the possibility of miscarriage.

The characteristics of the internal state of the fetus organs with Down syndrome:

large collar space;
small nose;
flat face;
underdevelopment of the little fingers;
hypotension;
eye diseases;
excessively movable joints.

After 20 weeks you can spend cordocentsis. This is an invasive technique, as a result of which the umbilical blood blood is taken. The diagnosis is carried out under anesthesia and causes a minimum of complications. But when identifying anomalies of development of the fetus, there is no possibility to make scraping. You can get rid of the child only by causing premature childbirth. This practice is used quite often in our country and minimizes the risk of infertility if desired to start a healthy child.
