Hydrocephalus can be treated, but care must be taken to identify the cause. Hydrocephalus is mainly caused by excessive production or absorption of cerebrospinal fluid, resulting in an excessive accumulation of cerebrospinal fluid in the skull, which produces various clinical symptoms. Therefore, it is very important to identify the cause and actively treat it symptomatically. The first is hydrocephalus caused by excessive secretion, such as choroid plexus papilloma, a tumor that produces excessive secretion of cerebrospinal fluid, resulting in hydrocephalus, and the treatment plan is to surgically remove the tumor. The second is obstructive hydrocephalus. For this kind of hydrocephalus, what we can do is to remove the obstructive factors or establish other cerebrospinal fluid circulation pathways to keep the cerebrospinal fluid circulation pathways stable and open again. For example, a third ventricular floor fistula can be performed. Finally, for unexplained hydrocephalus, ventriculoperitoneal or lumbar pool ventral shunt surgery can be performed at this time. The general procedure is to drain the excess cerebrospinal fluid generated intracranially into the abdominal cavity through a drainage tube and absorb it through the greater omentum of the abdominal cavity. This procedure is relatively mature, and the development of surgical equipment is relatively stable. As long as it is performed properly, there is no infection, and there are no postoperative complications, the treatment results are excellent. Therefore, for hydrocephalus, it is necessary to build up confidence, to conduct relevant examinations and tests in a timely manner, to clarify the changes in the condition, and to carry out early treatment.
