Cerebrospinal fluid shunting procedures are surgical interventions used to divert and regulate the flow of cerebrospinal fluid within the brain and spinal cord. These procedures are typically performed to treat conditions like hydrocephalus by redirecting excess fluid to another part of the body, such as the abdominal cavity, where it can be absorbed harmlessly. Proper shunt placement and monitoring are essential for effective management of cerebrospinal fluid dynamics.
