1.The Definition ➢ Hydrocephalus is not a kind of“disease”, but a pathological result induced by variety causes. ➢ Three main points：Increase of CSF（ 脑脊液增多）, Dilation of Ventricles（脑室扩大）and Intracranial Hypertension（颅内高压）
2.The History
2.The History ➢ The term hydrocephalus is derived from two words: ▪ "hydro" meaning water ▪ "cephalus" referring to the head ➢ 1875, Production, circulation and absorption of CSF ➢ 1923, Endoscopic Third Ventriculostomy ➢ 1949, Ventriculoperitoneal Shunt ➢ 1973, CT, follow by MRI ➢
3.Epidemiology ▣】in2,OO0 newborns suffer from hydrocephalus. Over 30,000 hydrocephalus babies born each year in China mainland. More than 50%cases were congenital previously but acquired are becoming predominant currently Death rates have decreased from 54%to 5%, intellectual disability has decreased from 62%to 30%
