Treatment: Shunts
Ventricular catheter (proximal catheter)
The ventricular catheter is the part of a shunt placed into a brain ventricle, where it collects cerebrospinal fluid for drainage.
In short: Ventricular catheter (proximal catheter)
- It is the shunt component placed into a ventricle.
- It collects CSF from the ventricle.
- It is also called the proximal catheter.
- Obstruction of it is a common cause of shunt malfunction.
What it is
The ventricular catheter (or proximal catheter) is the part of a shunt that is placed into a brain ventricle. It has small holes through which cerebrospinal fluid enters the shunt to be drained.
Understanding Ventricular catheter (proximal catheter)
Positioned within a ventricle (often a frontal or occipital horn of a lateral ventricle), the ventricular catheter is the entry point for CSF into the shunt system. From there, fluid flows through the valve and distal tubing to its destination. Because the catheter sits in the ventricle, its small holes can become blocked over time — for example, by choroid plexus, debris, or cells — making proximal catheter obstruction one of the most common causes of shunt malfunction. Proper placement of the catheter within the ventricle is important for reliable function, and when it becomes obstructed, it is a frequent reason for a shunt revision.
Why it matters
Understanding the ventricular catheter helps families see where the shunt collects CSF and why obstruction of this part — a common cause of shunt malfunction — is a frequent reason a shunt needs revision.
Common questions
What is the ventricular catheter?
The shunt part placed into a ventricle to collect CSF.
What is another name for it?
The proximal catheter.
Why can it cause malfunction?
Its holes can become blocked, a common cause of shunt failure.
Bottom line
The ventricular (proximal) catheter is the shunt part placed in a ventricle to collect CSF; its obstruction is a common cause of shunt malfunction.
