Hydrocephalus surgery is a high‑tech procedure to drain excess fluid from the brain’s ventricles, helping to reduce intracranial pressure and restore normal nervous system function. During the operation, a shunt with an adjustable valve is implanted: after the procedure, doctors can remotely adjust its settings using a special external device, tailoring fluid drainage to the patient’s individual needs. The surgery is recommended for various types of hydrocephalus—congenital, post‑traumatic, post‑infectious, and idiopathic. As a result, patients experience relief from elevated intracranial pressure, recovery of neurological functions, and a return to full, active living.
