OBJECTIVE: Endoscopic third ventriculostomy (ETV) is an effective treatment for occlusive @entity1276 caused by an obstruction of the CSF flow in the aqueduct or the posterior fossa. We evaluated the factors age, pathology and surgical technique on the results of the ETV. METHODS: Between November 1992 and October 2000 171 ETV have been performed in 159 @entity1 . The follow-up was evaluated in 150 @entity1 . The age ranged from 10 days to 77 years (mean age 35 years). The @entity1276 was caused by @entity1276 in 77 @entity1 , space-occupying lesions in 59, by intraventricular @entity548 in 11, and by other causes in 3 @entity1 . The trajectory was planned in 31 @entity1 by frame-based and in 4 @entity1 by frameless stereotaxy. RESULTS: The overall success rate of a single ETV was 71.3 % and including successful re-ETV 76.7 %. Best results were observed in adults and @entity1 older than 1 year. @entity1 demonstrated significantly worser outcomes. @entity1 with @entity1276 and @entity5 compressing the aqueduct had the greatest profit from the ETV. The stereotactic guidance had no influence on the outcome and the number of severe complications. Complications were one @entity548 , three @entity548 , and one ICB, all without permanent deficit, except one permanent @entity1269 . No mortality was observed.
