The vast majority of neonatal hydrocephalus can be cured. First of all, if the amount of hydrocephalus in a newborn is very small, most children can have the hydrocephalus absorbed by the body through the absorption of blood inside the brain. If the amount of hydrocephalus is very large, the child can be treated surgically in the brain surgery department of a children’s hospital. By surgically establishing a collateral circulation of cerebrospinal fluid, it is possible to reduce the amount of hydrocephalus produced by channeling excess cerebrospinal fluid into other pathways and draining it through other routes. In addition, some of the problems that cause hydrocephalus need to be addressed at the root. For example, children can have hydrocephalus due to brain tumors, so it is important to treat brain tumors promptly.
