Objective: Although endoscopic third ventriculostomy (ETV) is a well established procedure for the treatment of congenital and acquired hydrocephalus, there is still a controversy with regard to the higher risk of failure in younger infants compared to older children after such a procedure. The aim of this article is to define the effectiveness of third ventriculostomy for hydrocephalus in infants less than 6 months of age better and to determine possible positive predictive factors. Materials and Methods: In a series of 126 consecutive patients who underwent ETV between January 2000 and December 2002, 21 procedures were performed on infants ranging in age from 23 to 180 days, and without a previous history of shunting. The follow-up period was 49 to 82 months. Results: The overall Success rate of ETV was 67% (14/21). All failures occurred in the,early postoperative period (average 38 days, range 25-88 days). The success rate varied with the etiology of the patient's hydrocephalus. The best results were obtained in patients with acqueductal stenosis, Dandy-Walker malformation and myelomeningocele. The least favorable results (50% failure rate) occurred in infants treated for post-hemorrhagic and post-meningitic hydrocephalus. Conclusion: This study does not demonstrate a correlation between the age of the infants and the ETV success rate. The specific etiology of hydrocephalus is the most relevant prognostic factor in infants under six months of age.
