How common is shunt failure?

Failure rates in pediatric studies are even higher: 38% shunt failure rate at 1 year, going up to 48% at 2 years. By far, the two most common complications are shunt blockage and infection.

How often do 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.

How often do VP shunts fail?

VPS failure rates have been estimated at approximately 11–25% within the first year after initial shunt placement [[2], [3], [4], [5]], with most sources reporting a significantly higher number of shunt revisions and replacements among pediatric patients compared to adults [4,5].

What is the success rate of shunt surgery?

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.

How often should a brain shunt be checked?

All younger patients with a shunt should probably be encouraged to seek a neurosurgical check up at least every three years, ideally at a dedicated hydrocephalus follow up clinic.

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.

Why do shunts fail?

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.

What are symptoms of shunt failure?

What Are Signs of Shunt Malfunction?

  • Headaches.
  • Vomiting.
  • Lethargy (sleepiness)
  • Irritability.
  • Swelling or redness along the shunt tract.
  • Decreased school performance.
  • Periods of confusion.
  • Seizures.

Is VP shunt for life?

VP shunts do not work forever. When the shunt stops working: The child can have another buildup of fluid in the brain. Another surgery is needed to fix it.

How long can VP shunt last?

Shunting is successful in reducing pressure in the brain in most people. 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.
