An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
Ventriculostomy is a neurosurgical procedure that involves creating a hole (stoma) within a cerebral ventricle for drainage. It is most commonly performed on those with hydrocephalus. [1] . It is done by surgically penetrating the skull, dura mater, and brain such that the ventricular system ventricle of the brain is accessed.
11 de nov. de 2019 · Purpose of Review. The optimal management of external ventricular drains (EVD) in the setting of acute brain injury remains controversial. Therefore, we sought to determine whether there are optimal management approaches based on the current evidence. Recent Findings.

22 de jun. de 2022 · basics of what an external ventricular drain (EVD) is A burr hole is used to penetrate the skull, after which a catheter is blindly advanced into the lateral ventricle using anatomic landmarks. Among critically ill patients, the procedure is usually performed at the bedside.
23 de abr. de 2021 · KEY WORDS. External ventricular drainage, nursing care, CSF. INTRODUCCIÓN. El Drenaje Ventricular es la inserción de un catéter en el ventrículo lateral cerebral con salida hacia el exterior para el control de la presión intracraneal (PIC) y/o drenaje de líquido cefalorraquídeo (LCR).
13 de ago. de 2023 · Ventricular catheters represent a “global” ICP with minimal chances of drift and influence from pressure gradients between the parenchyma and ventricular system. It is the most reliable method of achieving maximum accuracy at minimal expense.
