Measurement Of Folds At The Nape Of The Fetus

During pregnancy, the mother will have to perform many tests and ultrasound to monitor the development of the fetus. In particular, measuring the fold in the nape of the fetus is a special type of ultrasound that can help detect the risk of some chromosomal abnormalities in the child.
So, how much time is in the fold and how much is considered normal will be fully explored in the following article.
What is the measurement of the fold in the nape of the fetus?
A fold or nuchal translucency measurement is performed using ultrasound to assess the risk of Down syndrome (DS) of the developing fetus and some other chromosomal abnormalities, as well as innate heart problem.
This test is done to measure the (translucent) space in the tissue at the back of the baby's neck. If the fetus is abnormal, there will be a tendency to accumulate more fluid in the back of the neck during the first trimester, making this clear space larger than average. Crease measurement at the back of the fetus is a non-invasive test.
In addition to measuring the nuchal translucency, this ultrasound also looks for the presence of the fetal nasal bone in the first trimester

If the nasal bone is not visible, this could be a sign of a chromosomal abnormality in the child.

The time to carry out the measurement of the fold in the nape of the fetus
Crease measurement at the nape of the fetus is done during the first trimester and usually from 11 to 14 weeks of pregnancy, because this is the time when the baby's neck is still clear. The last day a mother can have this type of ultrasound is when you are 13 weeks and 6 days old. In addition to relying on the gestational week, the time of measuring the folds in the nape of the fetus can be based on the head-buttock length (CRL) of the baby ranging from 45mm (1.8in) to 84mm (3.3in) )
Usually when taking a measurement of the skin of the back of the neck, the doctor will order more blood tests to look at the results of the combined test for a more accurate result of the child's chromosomal abnormalities.
It is difficult to measure the neck fold before 11 weeks because the baby is still too young and it is too early to combine with the mother's first trimester blood test. However, it is too late to perform this type of ultrasound after the 14th frequency since any excess fluid can be absorbed by the baby's developing lymphatic system

Therefore, an ultrasound scan of the gay skin fold or nuchal translucency will help doctors identify the signs of whether the child may have Down syndrome.
Like other screening tests, a nuchal fold measurement test will not give you an accurate diagnosis as to whether your baby has Down syndrome or a chromosomal abnormality. This ultrasound can only assess a baby's risk for certain problems, as well as help doctors and pregnant mothers decide whether or not to perform a chorionic villus sampling (CVS) or puncture. Amniotic fluid to find out if the baby is really affected.
However, diagnostic tests are at risk of miscarriage for a mother. Because of this, the obstetrician will want her mother to have a screening test before her appointment to perform the diagnostic test.

How is an ultrasound of the neck fold measurement done?
The person performing (ultrasound) will apply a small amount of gel to the pregnant woman's abdomen and move a handheld device (probe) on your skin. This procedure does not cause any damage, however, you may feel some pressure when the ultrasound doctor presses the transducer against your skin for a clearer image.

However, in case your uterus is tilted backwards or is overweight, the doctor may order a vaginal scan to get a better picture. This procedure is relatively safe for both you and the baby and does not cause too much discomfort.
This ultrasound method also helps determine the most accurate gestational age, the doctor will measure the length of the baby is calculated from the top of the head to the end of the spine. The doctor will then measure the width of the liquid at the back of the baby's neck. The skin will appear as a white line and the fluid under the skin will be black.
Usually, you will be able to see your baby's head, spine, limbs, hands and feet on the screen. The sonographer will be able to rule out some major abnormalities, such as problems with the baby's abdominal wall, stomach and skull, during this ultrasound.

8in) to 84mm (3.3in) and results from the measurement of the neck-fold fold below 3.5mm, it is considered normal. Results from the nuchal folds usually develop in proportion to the baby.
9/10 babies with a measurement from 2.5mm to 3.5mm will usually not have D syndrome.
