Health is a concern for everyone, but nowadays many diseases are highly prevalent and pose a threat to health without being aware of it. Hydrocephalus is not a single disease that we have all heard of, because the cerebrospinal fluid in the human skull is dynamic and is constantly being produced and absorbed, and if there is an abnormality in the production, circulation and absorption of cerebrospinal fluid and too much accumulates, hydrocephalus is formed. Hydrocephalus is a problem that should not be taken lightly and can cause great damage to health if left untreated. At first, the patient’s eyesight will gradually decrease, walking will become weak, intelligence will decline, and the whole person will look mentally tired. If it develops seriously, it can lead to long-term bed rest, urinary incontinence and even dementia, causing great pain to both the patient and his family. The treatment of hydrocephalus should not be delayed in any way, and the common method is hydrocephalus shunt surgery, which uses a tube to drain the excess cerebrospinal fluid from the ventricles to other parts of the body and absorb it. However, this conventional shunt surgery has proven to have a high failure rate and many complications, and some patients’ conditions can be recurrent and painful after surgery. What about recurrence of shunt surgery in patients with hydrocephalus? Patients must be aware that after the failure of the previous surgery, they should be more careful when choosing another surgery.
