How often do VP shunts fail?
A shunt is a delicate piece of equipment that can malfunction, usually by becoming blocked or infected. It’s estimated up to 4 in 10 shunts will malfunction in the first year after surgery. Sometimes, a scan after the operation shows the shunt is not in the best position and further surgery is needed to reposition it.
What is the success rate of shunt for hydrocephalus?
Currently, the ventriculoperitoneal shunt is a commonly used shunt configuration, with a success rate of up to 80% (8–10). The use of adjustable valves enables non-invasively readjusting the pressure (3). Careful selection of patients and preoperative screening for shunt surgery are crucial for better outcomes.
What is the lifespan of a VP shunt?
VP shunts are likely to require replacement after several years, especially in small children. The average lifespan of an infant’s shunt is two years. Adults and children over the age of 2 may not need a shunt replacement for eight or more years. Shunt systems require frequent monitoring and follow-up.
What is the most common cause of shunt failure?
Shunt malfunction is most commonly due to a blockage or some obstruction within the shunt system. If the blockage is not corrected, symptoms of hydrocephalus will return. In some cases, shunt blockage may require surgery to replace the affected component or components.
How do you know if a shunt is failing?
A shunt is said to have failed when any complication of the treatment of hydrocephalus requires surgery. Symptoms of a cerebral shunt malfunction may be obvious, redness over the shunt, headache, sleepiness, vomiting, or visual changes. Symptoms may also be subtle, change in behavior, change in school performance.
How common is shunt malfunction?
Forty percent of all shunts fail within the first year of placement. Infection can affect up to 10% of shunts. Only a third of shunts will remain revision free by 10 years of placement. Hemorrhage associated with ventriculostomies is more likely to occur in infants and is associated with shorter time to shunt revision.
Is VP shunt permanent?
There can be bleeding, or an infection can develop. VP shunts do not work forever. When the shunt stops working: The child can have another buildup of fluid in the brain.
Does hydrocephalus shorten life?
Hydrocephalus can be very serious, and even fatal, if left untreated. Fifty percent of those who fail to have their hydrocephalus treated will die. The other half survive with what is called arrested hydrocephalus. Those who are not treated and survive may have serious brain damage and physical disabilities.
Can you live a long life with a shunt?
Many people with normal pressure hydrocephalus enjoy a normal life with the help of a shunt. Regular, ongoing checkups with the neurosurgeon will help ensure that your shunt is working correctly, your progress is on track, and you are free to keep living the way you want.

What are the parts of a VP shunt?
Ventriculoperitoneal shunts consist of a valve and two tubes, called catheters, which drain the fluid. One catheter drains fluid from the brain out of a small hole the doctor makes in the skull. This is called the inflow catheter.
How do you get hydrocephalus?
Congenital hydrocephalus. Approximately 1 in every 500 American babies are born with hydrocephalus.
