Hydrocephalus surgery is relatively risk-free. Hydrocephalus is divided into acute hydrocephalus and chronic hydrocephalus. 1. Acute hydrocephalus: often caused by ventricular obstruction, patients with increased intracranial pressure, causing headache, nausea, vomiting and other manifestations, cranial CT examination to confirm the diagnosis, ventricular drainage, cerebrospinal fluid to the outside of the body, the risk of surgery is generally small. 2. Chronic hydrocephalus: manifested by cognitive decline, incontinence, unsteady walking, feasible ventriculoperitoneal shunt surgery. The surgical risk is also not significant. Regardless of the type of surgical treatment, careful postoperative care is needed to minimize the risks of the surgery as much as possible. Once hydrocephalus is detected, it is necessary to go to the hospital in time to confirm the diagnosis, identify the cause, and actively cooperate with the doctor’s treatment, so as not to be negligent, so as not to delay the condition.
