Hydrocephalus is a common clinical condition caused by the enlargement of the ventricular system or subarachnoid space due to the excessive accumulation of cerebral crest fluid in the skull, resulting in a series of neurological symptoms. Typical symptoms of hydrocephalus include headache, vomiting, blurred vision, optic nerve papilla edema, occasional diplopia, vertigo and seizures. Hydrocephalus is often treated clinically by shunt surgery, which is a procedure in which a tube is used to divert excess brain crest fluid from the skull to other parts of the body to be absorbed. The more common type of shunt is a ventriculoperitoneal shunt because the absorption capacity of the abdominal cavity is stronger. However, the problem of blockage after this type of hydrocephalus shunt is more common and has a very high probability of occurrence, which is a major problem for neurosurgeons. If postoperative blockage occurs, it is very dangerous and needs to be dealt with promptly. How can we tell if a tube is blocked after abdominal shunt? If blockage occurs, hydrocephalus will reappear and the ventricles will be enlarged, causing headache, vomiting, and high fever again, etc. Of course, the specific diagnosis requires scientific examination and evaluation by clinicians. The problem of blocked tubes after hydrocephalus shunt is a difficult problem in many hospitals. At present, a set of comprehensive treatment method of brain crest fluid department can effectively solve the problem of post-operative hydrocephalus blockage. Not only the problem of post-operative hydrocephalus tube blockage, but also this set of comprehensive therapy has remarkable The results and prognosis are good.
