Normally, the cerebrospinal fluid in our brain is in a constant state of equilibrium of production, circulation and reflux. However, under the influence of some cranial disorders, the equilibrium of cerebrospinal fluid is disrupted, causing abnormalities in the cerebrospinal fluid, resulting in an increase in the amount of cerebrospinal fluid in the skull, which leads to hydrocephalus. Hydrocephalus should not be taken lightly, as it can have a serious impact on the neurological function of the brain and cause a series of symptoms. Typical symptoms include headache, vomiting, blurred vision, edema of the optic nerve papillae, occasional diplopia, vertigo and seizures, and in severe cases, even life-threatening. At present, the clinical treatment of hydrocephalus is still mainly surgical. Hydrocephalus shunt is a common method for treating hydrocephalus, and the operation principle is: a tube is used to divert the excess water (cerebrospinal fluid) from the ventricles to the abdominal cavity to absorb it, and if the abdominal cavity is not in good condition, it can also be considered to be diverted to the thoracic cavity. Shunt surgery has certain advantages but also major drawbacks. The advantage is that with treatment, the amount of cerebrospinal fluid in the skull can be normalized and the symptoms can be greatly improved. The disadvantage is that there are many postoperative complications, such as intracranial infections, blocked shunts, etc. How long does a hydrocephalus shunt last? The exact length of time a hydrocephalus shunt will last depends on each patient’s condition, the shunt material, and other factors. When patients need to replace shunts for various reasons, they should choose a regular hospital to avoid many problems. At present, there is a set of advanced special treatment technologies that can effectively treat all kinds of hydrocephalus, and at the same time can well avoid post-operative blockage and infection.
