Endoscopic third ventriculostomy (ETV)
An endoscopic third ventriculostomy is a procedure that creates a new internal pathway for cerebrospinal fluid to treat some hydrocephalus, as an alternative to a shunt.
In short: Endoscopic third ventriculostomy (ETV)
- It creates an opening in the floor of the third ventricle.
- It can avoid the need for a shunt in suitable cases.
- It is not appropriate for every type of hydrocephalus.
- Its suitability depends on the cause and anatomy.
What it is
It is a procedure in which a surgeon, using an endoscope, makes a small opening in the floor of the third ventricle to create a new internal route for cerebrospinal fluid to flow and be absorbed. It is an alternative to placing a shunt for some children.
Understanding Endoscopic third ventriculostomy (ETV)
For suitable cases of hydrocephalus, ETV can restore CSF flow without a shunt device, avoiding shunt-related issues like malfunction. However, it is not appropriate for every type of hydrocephalus — its success depends on the underlying cause and the child's anatomy. The team assesses whether ETV or a shunt is the better option, sometimes in combination with other procedures. ETV may also be revisited if the opening closes over time.
Why it matters
Understanding ETV helps families see that there is an alternative to a shunt for some children, and why the choice between them depends on the specific cause and anatomy of the hydrocephalus.
Common questions
What does ETV do?
Creates a new internal CSF pathway in the floor of the third ventricle.
Is it an alternative to a shunt?
Yes, for suitable cases.
Is it right for everyone?
No — its suitability depends on the cause and anatomy.
Bottom line
ETV creates a new internal CSF pathway to treat suitable hydrocephalus, as an alternative to a shunt.
