There are so many clinical causes of hydrocephalus that it can occur after a single traumatic surgery. If left untreated, hydrocephalus can lead to a variety of neurological disorders, which can be very detrimental to health. Therefore, when hydrocephalus does occur, what you need to do is to address the condition and deal with it actively. First, let us introduce the dangers of hydrocephalus in detail. In mild cases, the main symptoms are dizziness, headache, nausea, and possibly blurred vision and unresponsiveness. In more severe cases, it may be combined with unstable walking, incontinence, progressive dementia, or even bedridden. Therefore, the danger of hydrocephalus should not be underestimated, and the correct approach is to go to a regular hospital for appropriate treatment in a timely manner. Medication is usually indicated for patients with mild symptoms, but in severe cases, surgery is required. Ventriculoperitoneal shunt is a common procedure in neurosurgery to treat hydrocephalus, which is relatively simple to perform and takes less time to operate. Some people ask, “At what level of hydrocephalus do I need a ventriculoperitoneal shunt? One is to do a CT examination to see if the ventricular system is progressively enlarged; the other is to do a lumbar puncture to measure whether the amount of cerebrospinal fluid exceeds the amount. Once the diagnosis is clear, surgery can be performed. A ventriculoperitoneal shunt uses a tube to shunt excess cerebrospinal fluid from the skull into the abdominal area to be absorbed. However, the problem of postoperative infection is more common with conventional shunt surgery, and the probability of blockage of the tube is very high and a major problem for neurosurgeons. This technique, which starts with long-range cerebrospinal fluid drainage and cerebrospinal fluid decontamination until the amount of cerebrospinal fluid reaches the standard and then performs a modified ventriculoperitoneal shunt, has achieved ideal results in the treatment of various types of hydrocephalus with a low chance of postoperative complications and a high degree of safety.
