Ventriculostomy is also called ventricular catherization with an intraventricular catheter (IVC) or external ventricular drainage (EVD). It is a surgical procedure that involves the placement of a catheter connecting the ventricles of the brain to an external collecting device.Endoscopic third ventriculostomy is an alternative surgical procedure that creates a bypass for the cerebrospinal fluid in the head that eliminates the need for a shunt. It is helpful only to people with hydrocephalus caused by a blockage of the flow of cerebrospinal fluid.In addition to its primary use as an ICP monitor, a ventriculostomy is commonly used in the ICU as a drain for patients with TBI or hydrocephalus. Common causes of acute hydrocephalus in an adult ICU include cerebellar stroke or hemorrhage, intraventricular hemorrhage, and aneurysmal subarachnoid hemorrhage.
Why do people need ventriculostomy?
Endoscopic third ventriculostomy is an alternative surgical procedure that creates a bypass for the cerebrospinal fluid in the head that eliminates the need for a shunt. It is helpful only to people with hydrocephalus caused by a blockage of the flow of cerebrospinal fluid.
When is ventriculostomy used?
In addition to its primary use as an ICP monitor, a ventriculostomy is commonly used in the ICU as a drain for patients with TBI or hydrocephalus. Common causes of acute hydrocephalus in an adult ICU include cerebellar stroke or hemorrhage, intraventricular hemorrhage, and aneurysmal subarachnoid hemorrhage.

Is a ventriculostomy the same as an EVD?
Ventriculostomy is a procedure allowing for cerebrospinal fluid (CSF) drainage from the cerebral ventricles to alleviate elevated intracranial pressure secondary to communicating or non-communicating hydrocephalus.
What is a ventriculostomy drain?
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.
How is ventriculostomy performed?
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. It is done by surgically penetrating the skull, dura mater, and brain such that the ventricle of the brain is accessed.
How is ventriculostomy done?
It involves drilling a small hole (burrhole) in the skull (normally on the right side behind the hairline) to allow a small video camera (endoscope) and miniaturised surgical instruments to access the third ventricle and create a new opening in the bottom of the third ventricle.
Is a ventriculostomy a shunt?
Key points. Hydrocephalus occurs when too much cerebrospinal fluid builds up, causing the ventricles to become larger and increasing pressure inside the head. Your child may require a ventriculostomy or a shunt to drain the CSF and relieve the pressure.

What is the major risk with an intraventricular catheter?
These risks include infection, collapse of the ventricles, rapid ventricular drainage, increased potential for subdural hematoma, and subarachnoid hemorrhage.
Is a ventriculostomy a craniotomy?
For less severe injuries a ventriculostomy is typically done, which is less invasive than a craniectomy. A craniotomy makes the same hole in the skull to access the brain, but the piece is replaced during the procedure.
How much should an EVD drain per hour?
| Newborn | 1mL/hr | 25mL/day |
|---|---|---|
| Children | 10-15mL/hr | 240-360mL/day |
| Adult | 20mL/hr | 500mL/day |
What are the principal risk factors associated with ventriculostomy procedure quizlet?
Risk factors associated with VAIs are subarachnoid hemorrhage (SAH), intraventricular hemorrhage IVH, craniotomy, and coinfection 5). The risk of infection increases with increasing duration of catheterization and with repeated insertions.

How long does it take to insert an EVD?
Inserting an EVD
The procedure takes about one to two hours. Before your child goes to theatre the surgeon will discuss the procedure with you and you will have to sign a consent form. The risks involved are small, but as with any surgery there is always a risk of infection and bleeding.
How long can an EVD stay in?
How long will the EVD last? This varies from child to child, depending on the reason why EVD was needed in the first place. However, it is a temporary method of draining CSF and is rarely used for more than 14 days. Your child will need to stay in hospital until the drainage system is removed.
What is the cause of water in the brain?
Hydrocephalus is caused by an imbalance between how much cerebrospinal fluid is produced and how much is absorbed into the bloodstream. Cerebrospinal fluid is produced by tissues lining the ventricles of the brain. It flows through the ventricles by way of interconnecting channels.
How long does a lumbar drain stay in?
The drain remains in place for 2 to 3 days. Even if you did not respond to a single large volume tap, this extended drainage may indicate that you could respond to a shunt.
How long does ETV surgery take?
The neurosurgeon.
Surgery is carried out by a neurosurgeon (a specialist in surgery of the brain and nervous system). The surgery usually takes one to two hours.
Where is an EVD placed?
The ideal location for EVD placement is the frontal horn of the right lateral ventricle, near the foramen of Monro. A left frontal location may be considered when right frontal placement is not possible owing to intracranial pathological findings.
Where do you level a ventriculostomy?
Levelling the EVD system
If the patient is supine with their head neutral, level the EVD system to the tragus of the ear. If the patient is lateral, level the EVD to the mid sagittal line (between the eyebrows). Every time the patient moves the EVD must be re-levelled.
Can a person with hydrocephalus live a normal life?
What is the prognosis? If left untreated, hydrocephalus can be fatal. Early diagnosis and successful treatment improve the chance for a good recovery. With the benefits of surgery, rehabilitative therapies, and educational interventions, many people with hydrocephalus live relatively normal lives.
Who is a candidate for endoscopic third ventriculostomy?
Age greater than 6 months with aqueduct stenosis or tectal tumor and no previous shunting can be considered as an ideal candidate for ETV. ETV works best as a primary procedure in obstructive hydrocephalus without evidence of prior infection or hemorrhage (Fig. 1).
Which is better ETV or shunt?
There are several benefits of an ETV versus a ventriculoperitoneal shunt. Compared to a shunt, there are no implanted foreign bodies, fewer incisions and an overall lower long term complication rate. This means there is less discomfort, a lower infection rate, and less time in the hospital.

Does everyone with hydrocephalus need a shunt?
People who have hydrocephalus usually need a shunt system for the rest of their lives. They require regular monitoring.
What does ETV mean in medical terms?
Endoscopic third ventriculostomy (ETV) is an alternative to shunt placement for treatment of hydrocephalus. The technique opens a hole inside the brain to re-establish effective flow of cerebrospinal fluid (CSF).
