Cerebrospinal Fluid Diversion
Surgical procedures to redirect cerebrospinal fluid when normal drainage is obstructed by tumor or treatment effects.
Full Definition
Cerebrospinal fluid diversion encompasses various surgical techniques used to manage hydrocephalus or increased intracranial pressure in neuro-oncology patients. These procedures, including ventriculoperitoneal shunts, external ventricular drains, and endoscopic third ventriculostomy, redirect CSF flow when tumors or their treatments obstruct normal pathways. Proper documentation distinguishes between temporary external drainage and permanent internal diversions, as this affects patient prognosis and treatment planning.
Usage
Usage note: Always specify the type of diversion procedure when mentioned in clinical documentation.
