Every mother needs to undergo an Nt value test during pregnancy, and under normal circumstances, an NT value exceeding 3mm is considered thicker. When doctors find that the NT value is too high, they will be particularly nervous, but many pregnant mothers do not know why. Is there a problem with NT checking for thicker points?
Under normal circumstances, the larger the value of nt, the higher the probability of fetal abnormalities. There are several reasons for the increase in nt values, the first of which is due to the accumulation of a large amount of lymphatic fluid in the neck. During the development of the fetus, the lymphatic vessels and veins in the neck are unobstructed. If nT examination is performed, it indicates that there is a large amount of fluid accumulation in this area. In mid pregnancy, it may become a severe lymphatic sac tumor.
Another reason is that the fetus has congenital heart malformation. Due to heart failure, the pulse pressure of the veins will increase, making it difficult for lymphatic fluid to flow back into the lymphatic vessels. The accumulation of a large amount will lead to an increase in the NT value.
Even if the fetus has normal chromosomes, those with congenital heart defects will still experience NT thickening. If the heart fails, it is the main cause of Nt thickening. People with heart failure may face serious obstacles in venous return, and not only that, the return of lymphatic fluid in the lymphatic vessels is also not smooth. Therefore, most of the lymphatic fluid accumulates in the neck, forming NT thickening. Persist in obtaining high NT values and seek timely advice from doctors.
