What to do if fetal lateral ventriculomegaly is enlarged? The standard for ultrasonic diagnosis of lateral ventriculomegaly is that the diagnosis can only be made when the width of the lateral ventricle is ≥10 mm. Lateral ventriculomegaly is generally divided into more detailed categories: 1. ≥10-12 mm, which is mild lateral ventriculomegaly. Width; 2. ≥12-15 mm, which indicates moderate lateral ventricular enlargement; 3. ≥15 mm or more, which indicates severe lateral ventricular enlargement. This severe lateral ventricular enlargement is what we call hydrocephalus. . Under normal circumstances, doctors call lateral ventriculomegaly of 10-12 mm critical enlargement. About 80% of fetuses with mild lateral ventriculomegaly are normal after birth. However, there are also some mildly enlarged fetuses. During regular examinations, it is found that the width of the lateral ventricles is gradually increasing. For example, this examination was 11-12 mm, and it has developed to 13-14 mm during the examination 2 to 4 weeks later. The width will be re-examined. It was found that it had become 14-15 mm again. This situation may indicate that the child will have neurological and intellectual disabilities after birth.

Too much water (cerebrospinal fluid) in the brain will occupy the brain\’s territory, reducing the brain\’s space, affecting the development of brain tissue, and thus affecting the baby\’s neurological development.
