OBJECTIVE: To describe the short-term operative success and the long-term reliability of endoscopic third ventriculostomy (ETV) for treatment of hydrocephalus and to examine the influence of diagnosis, age, and previous shunt history on these outcomes. METHODS: We retrospectively analyzed 203 consecutive patients from a single institution who had ETV as long as 22.6 years earlier. Patients with hydrocephalus from aqueduct stenosis, myelomeningocele, tumors, arachnoid cysts, previous infection, or hemorrhage were included. RESULTS: The overall probability of successfully performing an ETV was 89% (84-93%). There was support for an association between the surgical success and the individual operating surgeon (odds ratios for success, 0.44-1.47 relative to the mean of 1.0, P = 0.08). We observed infections in 4.9%, transient major complications in 7.2%, and major and permanent complications in 1.1% of 203 procedures. Age was strongly associated with long-term reliability. The longest observed reliability for the 13 patients 0 to 1 month old was 3.5 years. The statistical model predicted the following reliability at 1 year after insertion: at 0 to 1 month of age, 31% (14-53%); at 1 to 6 months of age, 50% (32-68%); at 6 to 24 months of age, 71% (55-85%); and more than 24 months of age, 84% (79-89%). There was no support for an association between reliability and the diagnostic group (n = 181, P = 0.168) or a previous shunt. Sixteen patients had ETV repeated, but only 9 were repeated after at least 6 months. Of these, 4 procedures failed within a few weeks, and 2 patients were available for long-term follow-up. CONCLUSION: Age was the only factor statistically associated with the long-term reliability of ETV. Patients less than 6 months old had poor reliability.
