Treatment: Shunts
Ventriculosubgaleal shunt
A ventriculosubgaleal shunt is a temporary shunt draining CSF into a space under the scalp, used mainly in small or premature infants.
In short: Ventriculosubgaleal shunt
- It drains CSF from a ventricle into a pocket under the scalp.
- It is a temporary, temporizing measure.
- It is used mainly in small or premature infants.
- It buys time until a permanent treatment is appropriate.
What it is
A ventriculosubgaleal shunt is a temporary shunt that drains cerebrospinal fluid from a ventricle into the subgaleal space — a pocket beneath the scalp. It is used mainly as a temporizing measure in small or premature infants with hydrocephalus.
Understanding Ventriculosubgaleal shunt
In very small or premature babies, placing a permanent shunt may not yet be appropriate (for example, because the baby is too small or the CSF still contains blood or protein from a hemorrhage). A ventriculosubgaleal shunt diverts CSF into a space under the scalp, where it collects and is partly absorbed, temporarily relieving the buildup. This buys time until the baby grows and the situation stabilizes enough for a permanent solution (such as a VP shunt or, in some cases, ETV). It is one of the temporizing measures used in managing post-hemorrhagic hydrocephalus in premature infants, alongside reservoirs and temporary drains.
Why it matters
Understanding the ventriculosubgaleal shunt helps families see how a temporary measure can relieve hydrocephalus in a small or premature baby, buying time until a permanent treatment becomes appropriate.
Common questions
Where does a ventriculosubgaleal shunt drain to?
A pocket under the scalp (the subgaleal space).
Is it permanent?
No — it is a temporary, temporizing measure.
Who is it used for?
Mainly small or premature infants.
Bottom line
A ventriculosubgaleal shunt is a temporary shunt draining CSF under the scalp, used in small or premature infants until a permanent treatment is appropriate.
