Patient's question:
Diagnosis criteria for fetal hydrocephalusDoctor's answer:
The width of the fetal lateral ventricle is less than one centimeter, and if it exceeds 1.5 cm, it is likely to be hydrocephalus. Under normal circumstances, the fetal ventricles widen as the gestational age increases before 32 weeks, and narrow after 32 weeks. The maximum width is 13.4 mm, and a width greater than 15 mm can be preliminarily diagnosed as mild hydrocephalus. Mild hydrocephalus requires regular follow-up, and it is generally absorbed on its own. Do not worry too much.
