Overview of hydrocephalus To understand hydrocephalus, one needs to know about cerebrospinal fluid. Cerebrospinal fluid is a colorless, clear liquid present in the ventricles and subarachnoid space that has certain roles in nutrition, transport, buffering, protection and support, as well as maintaining normal intracranial pressure. In other words, normal people have water in their brains. Hydrocephalus, on the other hand, refers to the abnormal production, absorption, circulation, and reflux of cerebrospinal fluid due to certain pathological hazards, and the excessive stock of cerebrospinal fluid in the skull, resulting in progressive dilation of the ventricular system or (and) dilation of the subarachnoid space, called hydrocephalus. Symptoms of hydrocephalus Patients with hydrocephalus often present with intermittent headache, head swelling, head sinking, dizziness, tinnitus and ear blockage, decreased vision, etc. Some patients have a slow pulse, increased blood pressure, respiratory disturbances, and altered pupils; some patients may have eye movement disorders, cone bundle signs, and exhibit internal distension syndromes such as vomiting, gastrointestinal bleeding, neurogenic pulmonary edema, uveitis, cerebral-type sodium retention, and cerebral salt depletion syndrome. Treatment of hydrocephalus Shunt surgery is a common method for treating hydrocephalus, and one of the more classic procedures is ventriculoperitoneal shunt, in addition to ventriculoatrial shunt and ventriculothoracic shunt. This treatment is generally more effective upfront, and can generally normalize the amount of cerebrospinal fluid in the skull, and the corresponding symptoms will generally be significantly relieved. However, one of the more significant problems with this conventional shunt procedure is that the rate of postoperative complications is very high and poses serious problems. What about the sequelae of hydrocephalus shunts? What about the sequelae of hydrocephalus bypass? The sequelae mentioned here may refer to postoperative complications. The common complications of hydrocephalus shunts are postoperative infection and blockage of the shunt tube, and the infection and blockage rates of conventional shunt surgery are relatively high. What should be done when such complications occur? It is very important to choose a correct treatment method in time. At present, there is a complete set of systematic and targeted solutions for post-shunt complications, such as infection and blockage, through a series of specialized techniques such as long-range drainage of cerebrospinal fluid, cerebrospinal fluid purification, precise anti-infection treatment, ventricular wall normalization treatment, and new and improved shunt surgery, to achieve the desired treatment effect.
