摘要: Object The goal of this study was to externally validate the proposed Endoscopic Third Ventriculostomy Success Score (ETVSS), which predicts successful treatment for hydrocephalus on basis a child's individual characteristics. Methods authors retrospectively identified 181 cases consecutive endoscopic third ventriculostomy (ETV) performed in children at single neurosurgery center United Kingdom. They compared actual success both 6 and 36 months, with mean predicted probabilities low, moderate, high chance strata based ETVSS. Long-term calculated using Kaplan-Meier methods comparisons were made by means unpaired t-tests. Results Overall, 166 primary ETVs performed; ETV 72.9% 64.5% months. At long-term follow-up, probability significantly higher those (99 patients) than failed (67 (p = 0.001). ETVSS accurately pred...
