When it comes to hydrocephalus, many people are puzzled, can the brain really be filled with water? In fact, the water referred to here is a colorless and transparent liquid, namely cerebrospinal fluid, which fills the entire ventricle and subarachnoid space and is in a state of constant production and circulation, and when cerebrospinal fluid circulation is impaired, the amount of cerebrospinal fluid keeps accumulating, which leads to the formation of hydrocephalus. In other words, hydrocephalus is actually a state in which the cerebrospinal fluid circulation in the cranial cavity becomes metabolically disturbed, and it is not a single disease, but is caused by a variety of factors. If hydrocephalus does occur, it must be treated in a timely manner, otherwise the problem will be serious enough to destroy brain function and cause intellectual problems, and even epilepsy and death. The conventional surgical method is hydrocephalus shunt surgery, but there are more complications after conventional shunt surgery, such as blocked shunts, and some patients also have intracranial infections, resulting in fever that does not go away, so the problem becomes more difficult. What should I do if I have a fever due to intracranial infection in hydrocephalus? When hydrocephalus is complicated by intracranial infection, this condition is more dangerous and anti-infection treatment should be actively carried out. However, it is not enough to rely on medication alone because there is a blood-brain barrier in the human cranial cavity and anti-infection medication cannot enter directly, so surgery is necessary for better treatment control.
