No one wants to experience the pain of being ill, but some diseases still occur suddenly. Nowadays, the incidence of various craniosynostosis is very high, and some patients have to undergo craniotomy because they suffer from certain craniosynostosis. I thought there was nothing wrong with the craniotomy, but the postoperative intracranial infection led to severe hydrocephalus, which is another great threat to health. It may be said that hydrocephalus is still relatively common in neurosurgery, and it is a pathological result induced by a variety of causes, and the impact is very serious if not treated actively. What should I do if hydrocephalus is not absorbed after craniotomy? Hydrocephalus is a common complication after craniotomy, which may be due to postoperative obstruction of certain intracranial structures or restricted cerebrospinal fluid absorption circulation. It is important to pay attention to the non-absorption of hydrocephalus, and many hospitals are now offering treatment for this. This is the classic treatment method, in which a tube is used to divert excess cerebrospinal fluid from the ventricles of the brain to other parts of the body and absorb it. Although hydrocephalus bypass is not a major surgery, it can be prone to postoperative complications, such as intracranial infection, fever, headache, vomiting and other symptoms that can be life-threatening if not treated promptly. Therefore, in order to better ensure the safety and effect of the surgery, patients must go to a professional and regular hospital for treatment as soon as possible.
