Hydrocephalus is a disease that may be frequently encountered in the clinical work of neurosurgery, mainly caused by excessive cerebrospinal fluid collection. The incidence of hydrocephalus is relatively high. According to relevant statistics, the incidence of congenital hydrocephalus in newborns in China is 11.84 cases per 10,000, accounting for 56.25% of neurological defects in newborns. The incidence of post-traumatic hydrocephalus is 4.5%, and it can develop in almost all age groups. Old people over 60 years old usually have normal pressure hydrocephalus, children have congenital hydrocephalus, and young people have secondary hydrocephalus. Hydrocephalus can cause severe damage to a person’s brain function, including intellectual, motor, and visual impairment. In terms of intelligence, the obvious manifestations are reduced intelligence and dementia, while in terms of movement, such as limb movement is limited, unable to walk, unable to carry things, and in severe cases, unable to take care of themselves. Blindness of both eyes and hearing loss are all manifestations of visual impairment. Some patients with severe cases may even have life-threatening conditions. Therefore, patients with hydrocephalus should be treated promptly. Some local hospitals may have limited medical conditions, and many patients may choose to go to Beijing because they cannot get good treatment in the local area. Hydrocephalus shunt is a common procedure for treating hydrocephalus, but there is a problem that needs to be noted, as this procedure is more likely to cause infection and blockage after surgery. The current specialty technology for cerebrospinal fluid can be targeted to solve problems such as infection or blockage after shunt surgery. Through a series of specialized techniques such as long-range drainage of cerebrospinal fluid, cerebrospinal fluid purification, precise anti-infection treatment, ventricular wall normalization treatment, and a new and improved shunt procedure, we can achieve ideal treatment results.
