Many people do not pay attention to their diet and lifestyle habits, and as a result, they create the opportunity for some diseases to occur, but there are also many diseases that may not be caused by diet or habits, but they all threaten human life and health. Hydrocephalus is a very common condition, if suffering from some cranial disease or cranial injury can easily cause hydrocephalus. Once hydrocephalus occurs, the operation of the intracranial tissues will be affected and must be taken seriously. The former is a pathological phenomenon caused by malabsorption or excessive secretion and excretion of cerebrospinal fluid, while the latter is a pathological phenomenon caused by congenital or acquired factors that block the circulatory pathway of cerebrospinal fluid above the fourth ventricle and obstruct the flow of cerebrospinal fluid into the subarachnoid space (or the medulla oblongata pool of the cerebellum). Regardless of the type of hydrocephalus, it can pose a great threat to health, so it must be treated before it is too late. Currently, the treatment of hydrocephalus is mainly surgical, with medication as an adjunct. However, after a large number of treatment cases, it has been verified that there are many complications after conventional hydrocephalus shunt surgery, and patients may have different degrees of infection and blockage of the shunt. How does neurosurgery treat hydrocephalus? Specialized cerebrospinal fluid technology can effectively shunt and purify the cerebrospinal fluid while also providing better treatment to the ventricular and abdominal walls of the patient, truly avoiding complications and bringing hope to the patient’s recovery.
