Ventriculoperitoneal (VP) shunt
A ventriculoperitoneal shunt drains excess cerebrospinal fluid from the brain's ventricles to the abdomen.
In short: Ventriculoperitoneal (VP) shunt
- It is the most common type of shunt for hydrocephalus.
- It drains CSF to the abdomen, where it is absorbed.
- It includes a valve to regulate flow.
- It can require revision over time.
What it is
It is the most common type of shunt, draining excess cerebrospinal fluid from the brain's ventricles, through tubing under the skin, to the abdominal cavity (peritoneum), where the fluid is absorbed.
Understanding Ventriculoperitoneal (VP) shunt
When hydrocephalus accompanies encephalocele, a VP shunt relieves pressure by diverting CSF to the abdomen. The tubing runs under the skin, and a valve regulates flow. Like other shunts, it is effective but can occasionally malfunction or become infected, so families learn the warning signs (such as those of increased pressure), and revision surgery is sometimes needed over time. For some children, an ETV is considered as an alternative.
Why it matters
Understanding the VP shunt helps families see how the most common shunt works, why monitoring for malfunction or infection matters, and that revisions can be part of long-term care.
Common questions
Where does a VP shunt drain?
To the abdomen, where the fluid is absorbed.
Is it common?
Yes — it is the most common type of shunt.
Can it need revision?
Yes, over time.
Bottom line
A VP shunt drains excess CSF from the ventricles to the abdomen and is the most common shunt for hydrocephalus.
