The morning we brought my son home from hospital, I found myself staring at the small ridge under the skin behind his ear.
The shunt. A thin tube running under his scalp, behind his ear, down his neck, into his abdomen. Keeping the fluid balanced in his brain. Keeping him alive.
It was invisible to anyone who did not know it was there. To me it was the only thing I could see.
We had been given a printed sheet of instructions. Keep the incision clean. Watch for fever. Return to emergency if he becomes suddenly drowsy or starts vomiting repeatedly. Call the clinic number if you have concerns.
What the sheet did not tell us was how to live with this thing. How to think about it on ordinary days. How to explain it to family members who did not understand. Whether he would be able to swim, to play football, to travel on a plane. What his teenage years would look like. What his adult life might hold.
This article is the guide we needed and did not have.
What a VP Shunt Actually Does — Day to Day
A ventriculoperitoneal shunt is a drainage system. It consists of a catheter placed in one of the brain’s ventricles, a valve that regulates flow, and a second catheter that carries excess cerebrospinal fluid down to the peritoneal cavity in the abdomen, where the fluid is safely absorbed.
On most days, it does its job silently. A child with a functioning shunt can live a full, active life. The shunt does not hurt. It does not make noise. In most children it is entirely invisible under normal clothing.
But it is also a mechanical device. And mechanical devices can fail.
The Most Important Thing Every Shunt Family Must Know: Failure Signs
Shunt failure is not rare. Studies consistently show that approximately 40% of paediatric shunts require revision surgery within two years of placement, and up to 85% will need at least one revision during a child’s lifetime.
Failure can happen suddenly or gradually. It can happen years after a shunt has been working perfectly. Every family living with a shunt must know these signs and be prepared to act on them immediately:
Signs of possible shunt failure — seek urgent medical attention:
- Sudden, severe headache — especially one that is different from any previous headache
- Repeated vomiting without obvious cause
- Extreme drowsiness or difficulty waking
- Vision changes — double vision, blurred vision, downward deviation of the eyes
- Seizures in a child who has not had them before — or increased seizures in a child who does
- Swelling, redness or pain along the shunt tract (the line under the skin from head to abdomen)
- Return of symptoms that were present before the shunt was placed
In an infant, also watch for:
- Bulging fontanelle (soft spot)
- Rapid increase in head circumference
- Unusual irritability that cannot be explained by other causes
If you observe any of these: do not wait for a clinic appointment. Go to the emergency department and tell them your child has a VP shunt and you are concerned about shunt failure.
Activities and Physical Life
One of the most common questions families ask is: what can my child do?
Swimming and water activities
Generally safe once the surgical incision is fully healed — typically six to eight weeks post-surgery. The shunt itself is internal and waterproof. Check with your surgeon before your child’s first swim.
Contact sports
This requires individual discussion with your neurosurgeon. Mild contact is generally tolerable. High-impact contact sports — rugby, martial arts, collision sports — carry a small but real risk of shunt displacement or damage. Many families develop a pragmatic approach based on their child’s specific shunt position and the sport in question.
Air travel
Generally safe. The pressure changes in a commercial aircraft cabin do not significantly affect VP shunts. Some children with programmable shunts need their settings checked after MRI scans, but standard air travel does not require adjustment.
Physical education and playground activities
Most children with functioning shunts can participate fully. The shunt does not need to be protected from ordinary childhood activity.
MRI and Medical Imaging
Standard MRI is safe for most VP shunts. However, if your child has a programmable shunt — one with adjustable valve settings — an MRI can sometimes alter the valve setting. This is not dangerous, but the setting will need to be checked and potentially adjusted after the scan.
Always inform any medical team performing imaging that your child has a VP shunt and what type it is. Carry a shunt identification card if your neurosurgeon provided one.
Talking to Schools and Carers
Every person who regularly cares for your child needs to know that your child has a VP shunt, what shunt failure looks like, and what to do if they observe concerning symptoms. This includes teachers, school nurses, childminders, grandparents, and coaches. Keep it simple and factual. A short written summary kept on file at school is more reliable than a verbal briefing.
The Emotional Reality — For Parents
Living with a child who has a shunt changes how you experience ordinary life.
A headache is never just a headache. A quiet afternoon becomes something to monitor. A fever triggers a level of vigilance that parents of neurologically typical children do not carry.
This is exhausting. It is also normal.
Many shunt families describe a gradual process — not of forgetting the shunt, but of learning to live alongside the awareness of it without being consumed by it. This takes time. It takes experience. And it takes, for many families, the support of other parents who understand.
Connecting with hydrocephalus parent communities — online and in person — can significantly reduce the isolation that comes with this kind of vigilance. You are not the only family learning to carry this.
When Your Child Asks About the Shunt
Children ask. Sometimes they ask early — pointing to the ridge under the skin and wanting to know what it is. Sometimes they ask later, when they notice that other children do not have the same thing.
Answer simply and truthfully at whatever developmental level is appropriate. “It is a little tube that helps your brain stay healthy. It has been there since you were small.” Most children, given an honest and calm answer, accept this remarkably well.
As they grow older, involve them increasingly in understanding their own condition. A teenager who understands their shunt, knows the warning signs, and can advocate for themselves in a medical setting is better equipped than one who has been shielded from the information.
Long-Term Outlook
Most children with hydrocephalus who receive appropriate treatment and follow-up go on to lead meaningful, active lives. The shunt becomes part of their story — not the whole story.
My son has a shunt. He also has a laugh that fills a room. He is learning to walk farther every week. He knows the names of more dinosaurs than I do. The shunt is one fact about him. It is far from the most interesting one.
