Hydrocephalus is a condition that often occurs in neurosurgery. Many people may be surprised when they hear about hydrocephalus, but the water mentioned here is a colorless, clear liquid, cerebrospinal fluid. Under normal circumstances, cerebrospinal fluid exists in constant amounts in the brain, but if certain factors affect the cerebrospinal fluid circulation, this can lead to the accumulation of too much cerebrospinal fluid, resulting in the formation of hydrocephalus. The main clinical symptoms of hydrocephalus include headache, nausea and vomiting, blurred vision, vertigo and seizures. If hydrocephalus is not treated in time, it can be very harmful. Hydrocephalus can damage brain function and cause various neurological dysfunctions, as well as affect intelligence. Treatment of hydrocephalus should not be delayed, and the effect of medication alone is not very obvious, and most of them require surgical solutions to better solve the problem. The conventional surgical procedure is hydrocephalus shunt surgery, which involves using a shunt tube to divert excess cerebrospinal fluid from the ventricles to other parts of the body to be absorbed. What are the chances of infection after hydrocephalus shunt surgery? This should be a concern for patients, as some patients do experience infections after hydrocephalus shunts, and some even experience blockage of the shunt, which can mean failure of the procedure and require rescheduling of treatment after a comprehensive evaluation by the physician.
