Surgery is available for hydrocephalus, and surgical treatment is only for patients with more obvious symptoms of hydrocephalus. When patients have symptoms such as headache, nausea, vomiting, unsteadiness in walking, memory loss, slowed thinking and reaction, and urinary and fecal disorders, then surgical treatment for hydrocephalus is required. There are usually two types of surgical procedures, one is ventriculoperitoneal shunt for hydrocephalus, which is suitable for all types of hydrocephalus, including traffic hydrocephalus and obstructive hydrocephalus, and involves continuous drainage of hydrocephalus into the abdominal cavity through a drainage tube and a shunt pump, which is absorbed by intra-retinal absorption of the greater omentum. There is also a third ventricular base fistula, which takes a neuroendoscopic approach to reach the base of the third ventricle through a hole in the skull for fistula, allowing the hydrocephalus to infiltrate into the subarachnoid space and participate in the cerebrospinal fluid circulation in the subarachnoid space, thus relieving hydrocephalus. This procedure is only suitable for obstructive hydrocephalus.
