A left lateral ventricle of 12mm at 25 weeks is usually normal.
Normally, fetal ventricles widen with increasing gestational weeks before 32 weeks and narrow with increasing gestational weeks after 32 weeks. The maximum width is 13.4mm, and greater than 15mm can be initially diagnosed as mild hydrocephalus. Therefore, a left lateral ventricle of 12mm at 25 weeks is generally normal.
It is recommended to take oral folic acid tablets in the trimester before and after pregnancy to prevent fetal malformation. Pay attention to rest and avoid staying up late. Nutrition should be varied, ensure the intake of high-quality protein, eat fresh vegetables and fruits. It is also necessary to ensure the intake of minerals and trace elements, so that the weight of pregnant women is controlled within a reasonable range.
If the fetal ventricular range value is abnormal, it is recommended to go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
