Anencephaly and spina bifida form the anomaly group called
"neural tube defects". Neural tube defects occur at a rate of 1-2 per
1000 births. In order to prevent these anomalies, each pregnant woman should
use a vitamin called 0.4 mg folic acid daily before the pregnancy and until the
3rd month of pregnancy. The frequency of neural tube defects decreases with the
use of folic acid.
Anencephaly skull is an anomaly characterized by the upper
part of cranium and the absence of the brain. It is seen 1 in 1000 births. The
absence of cranium, that is, cranium, is called perania or exencephaly
(exencephaly). Anencephaly is easily recognized by ultrasound in the 3rd - 4th
months of pregnancy. The reason is not known clearly. In the second - third trimesters
of pregnancy, polyhydramnios (increase in amniotic water) develops by 50%.
Pregnancy needs to be terminated. 75% of anencephalic fetuses
are born still, and babies born alive are impossible to survive, those alive
during childbirth die within a few hours.
In the case of anencephaly, the level of AFP (MS-AFP)
increases in the mother's blood.
