Lateral ventricular expansion generally does not affect the infant's intelligence. If it is a simple lateral ventricular dilation, the expansion does not exceed 15 mm, there is no other abnormality, the fetus will be slowly absorbed in the later stage, if absorbed to a normal level within 10 mm, it will not affect the intelligence of the fetus.
However, lateral ventricular dilation can also affect fetal intelligence and development.
1. If it is found that the lateral ventricle dilation is caused by chromosomal abnormalities, such as trisomy 21 abnormalities, that is, Down syndrome, the fetus is congenitally mentally retarded, and it is recommended that pregnant women terminate pregnancy.
2. If congenital abnormal brain structure development or viral infection causes lateral ventricular widening, it will affect fetal intelligence.
3. If the width of the fetal lateral ventricle exceeds 15mm and is diagnosed by the doctor as hydrocephalus, due to a large amount of water in the brain, the space for brain development is correspondingly reduced, thus affecting the intellectual development of the fetus.
4. If regular examination, it is found that the width of the lateral ventricle is gradually increasing. For example, at this time, the inspection width is 11~12mm, which develops to 13~14mm after 2~3 weeks, and then checks and finds 14~15mm. This condition may indicate neurological and intellectual impairment after birth.
Therefore, according to the principle of eugenics and fertility, in the above cases, doctors will recommend pregnant women to induce labor.
