Hydrocephalus surgery refers to surgical procedures performed to treat hydrocephalus, a condition characterized by the accumulation of cerebrospinal fluid (CSF) in the brain, leading to increased pressure within the skull. The goal of hydrocephalus surgery is to reduce this pressure and restore normal CSF flow and absorption, thereby alleviating symptoms and preventing complications associated with untreated hydrocephalus. There are several surgical approaches used to treat hydrocephalus, depending on the underlying cause and severity of the condition.
