Hydrocephalus is a relatively common condition in neurosurgery. It is mainly caused by the disruption of the equilibrium of intracranial cerebral crestal fluid, which results in an excessive amount of cerebral crestal fluid and leads to a series of diseases. It is essential for the central nervous system to buffer, protect, nourish, transport metabolites, and maintain normal intracranial pressure. The crestal fluid is in a state of constant equilibrium of production, circulation and reflux, and the total amount is basically constant, not less and not more. However, certain cranio-cerebral disorders may lead to excessive secretion of cerebral crest fluid, or impaired circulation and absorption, resulting in excessive accumulation of cerebral crest fluid in the skull. This can lead to enlargement of the ventricular system and the subarachnoid space, resulting in a series of neurological symptoms, such as headache, vomiting, blurred vision, optic nerve papillary edema, occasional diplopia, vertigo and seizures, etc. In severe cases, it may even be life-threatening. So can severe hydrocephalus be cured? Of course, it can be cured, but it is also difficult. One of the classic clinical treatment methods for hydrocephalus is bypass surgery, such as ventriculoperitoneal shunt, ventriculoatrial shunt, etc. More commonly, ventriculoperitoneal shunt is used because the absorption capacity of the abdominal cavity is stronger. However, this kind of hydrocephalus shunt surgery also has some disadvantages, that is, it has a relatively high incidence of postoperative complications, such as postoperative infection or postoperative shunt blockage, which can sometimes be as high as 40% or more in many places. In fact, these can be prevented and avoided by professional specialist cerebral crest fluid means.
