There are always diseases that inevitably appear around us in life and pose a serious threat to health. Hydrocephalus is one of the diseases with a high incidence in neurosurgery in recent years. The formation of hydrocephalus is naturally dependent on cerebrospinal fluid, which is normally produced and absorbed by the human brain. However, when the cerebrospinal fluid circulation is impaired by certain factors, the cerebrospinal fluid in the skull becomes excessive, and hydrocephalus develops over time. The current treatment plan for hydrocephalus is still relatively clear, with surgery as the main treatment and medication as a secondary treatment. For surgery, different patients can be targeted for shunting or drainage. Many patients are concerned about what to do about infection after hydrocephalus abdominal drainage? Hydrocephalus drainage is to draw cerebrospinal fluid out of the body, used to relieve the symptoms of the acute phase, postoperative infection may occur, but we do not need to worry too much, once the infection occurs, timely to the hospital symptomatic treatment, can greatly reduce the degree of harm. In fact, not only infection can occur after hydrocephalus drainage, but also complications such as intracranial infection and shunt blockage can occur from time to time after shunt surgery, which is a routine and classic procedure. Shunt operation is relatively simple and short, taking a tube into the ventricle, then passing under the skin, installing a shunt pump and then draining the tube through the skin into the abdominal cavity (chest or atrium), but the failure rate of the operation is also relatively high. However, with the rapid progress of medicine, the field of neurosurgery has seen unprecedented developments in both preoperative diagnosis and surgical techniques, especially with improved shunts, which can greatly reduce the chance of complications. Therefore, if you have hydrocephalus, you should not avoid treatment and go to a regular hospital as soon as possible to take effective treatment measures in order to recover as soon as possible. The specialized technology of cerebrospinal fluid neurosurgery, which is more comprehensive and makes up for the shortcomings of traditional treatment, has gained a high degree of medical recognition.
