Shunt valve
A shunt valve is the part of a shunt that regulates the flow of cerebrospinal fluid.
In short: Shunt valve
- It controls how much CSF drains.
- Some valves can be adjusted without surgery.
- It is a key component of a shunt system.
- It helps maintain appropriate pressure.
What it is
It is the component of a shunt system that regulates the rate at which cerebrospinal fluid drains. It helps ensure the right amount of fluid is diverted to maintain appropriate pressure.
Understanding Shunt valve
By controlling flow, the valve helps prevent draining too much or too little CSF. Some valves are adjustable, allowing the drainage setting to be changed without surgery (often using a special device over the skin). The valve is a key part of the shunt's function, and its setting may be tailored to a child's needs over time.
Why it matters
Understanding the shunt valve helps families see how a shunt is regulated and why some valves can be adjusted non-surgically to fine-tune drainage as a child grows or as needs change.
Common questions
What does the shunt valve do?
Regulates the flow of CSF.
Can it be adjusted?
Some valves can be adjusted without surgery.
Is it part of the shunt?
Yes — a key component.
Bottom line
A shunt valve regulates CSF flow through a shunt, and some valves can be adjusted without surgery.
