Although hydrocephalus has a high clinical incidence, it is not as common as hypertension and cervical spondylosis, so some patients and their families have never heard of it. It is not until they go to the hospital and undergo an examination that they learn they have hydrocephalus, and they are filled with tension and fear. The concept of hydrocephalus is well understood from the word “hydrocephalus”, which means that too much fluid is gathered in the brain. The medical name for this fluid is cerebrospinal fluid, which is normally white and clear. Hydrocephalus is also caused by excessive secretion of cerebrospinal fluid, impaired absorption of cerebrospinal fluid, and impaired circulation of cerebrospinal fluid. Therefore, the key to treating hydrocephalus is to remove the excess cerebrospinal fluid from the brain. Clinical classification of hydrocephalus Hydrocephalus is divided into obstructive hydrocephalus and communicating hydrocephalus according to the pathology. Obstructive hydrocephalus is the more common type, formed when the lesion is located in or near the ventricular system and obstructs the cerebrospinal fluid circulation in the ventricular system. Traffic hydrocephalus is hydrocephalus due to obstruction of the extraventricular cerebrospinal fluid circulation pathway or impaired absorption. Hydrocephalus can be divided into traumatic hydrocephalus, otogenic hydrocephalus, infectious hydrocephalus, occupying hydrocephalus, hemorrhagic hydrocephalus, acute hydrocephalus, chronic hydrocephalus, normal intracranial pressure hydrocephalus, and resting hydrocephalus according to the etiology. Different types of hydrocephalus present with different symptoms and different treatment options. Treatment of hydrocephalus Most patients with hydrocephalus are very concerned about treatment after their condition has been diagnosed. After understanding the traditional ventriculoperitoneal separation, they find that there are some shortcomings and then delay the surgical operation, which delays the early treatment and leads to the aggravation of the condition. In fact, there are currently more advanced surgeries to cure hydrocephalus in cities with rich medical resources such as Beijing and Shanghai. At present, there is a set of advanced specialist characteristic treatment techniques that can meet the needs of different hydrocephalus and intracranial infection patients and achieve scientific treatment.
