Rate and risk factors for shunt revision in pediatric patients with hydrocephalus during a 17-year study period: a retrospective, population-based study

Out of the 92 shunted patients, 54.3% underwent revision surgery, with most revisions occurring within the first year after initial VPS placement. Patient characteristics, such as congenital defects and age under 6 months, were associated with a higher risk for shunt revision. The use of the Strata adjustable valve did not have a statistically significant impact on shunt revision rates.
