ventriculostomy
Pronunciation: ven-TRIK-yoo-LOS-toh-mee
Surgical creation of an opening into the cerebral ventricles for CSF drainage or intracranial pressure monitoring.
Full Definition
A neurosurgical procedure involving the placement of a catheter through a small burr hole into the lateral ventricle of the brain. This procedure allows for continuous drainage of cerebrospinal fluid, measurement of intracranial pressure, and administration of medications directly into the ventricular system. Ventriculostomy is commonly performed in cases of hydrocephalus, subarachnoid hemorrhage, or traumatic brain injury where CSF diversion is necessary. The procedure may be temporary or serve as a bridge to permanent shunt placement.
Usage
Usage note: Often abbreviated as EVD (external ventricular drain); distinguish from permanent shunt systems.
