The cerebrospinal fluid (CSF) in the human brain is in a constant state of production, circulation, and reflux, and the measured amount of CSF supports and protects the brain and spinal cord. However, when the balance of cerebrospinal fluid is disrupted by certain cranial diseases or cranial surgery, the amount of cerebrospinal fluid increases and hydrocephalus develops. Hydrocephalus sounds bad, it will affect the patient’s cerebral nerve function to a certain extent, thus causing a series of uncomfortable symptoms. Typical symptoms of hydrocephalus are headache, dizziness, accompanied by nausea and vomiting, blurred vision, optic nerve papillae edema and seizures, etc., which can be life-threatening in serious cases and should not be ignored. The treatment of hydrocephalus should be done before it is too late. Currently, the treatment of hydrocephalus in clinical practice is mainly based on surgery, and the conventional surgical method is hydrocephalus shunt surgery, which is a procedure that uses a shunt tube to shunt the excess cerebrospinal fluid within the ventricles of the brain to the abdominal cavity or other parts of the body to be absorbed. How many years does a hydrocephalus shunt last? This should be a question that patients are very concerned about, but it is very difficult to determine. Generally speaking, if there are no other conditions after the operation, the shunt can work all the time, but if the patient develops problems such as shunt blockage and infection after the operation, it is hard to say, and the shunt will have to be taken out again and retreated, which is a difficult problem faced by the medical science nowadays.
