The goal of this study was to assess the risk of failure associated with these factors in a retrospective cohort study.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>Between 1999 and 2007, 368 ETVs were performed in 350 patients (165 patients &lt; 18 years of age) with hydrocephalus at the University Hospital of Toulouse. Failure of ETV was defined as cases requiring any subsequent surgical procedure for CSF diversion or death related to hydrocephalus management.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Tumors (53%), primary aqueductal stenosis (18%), and intracranial hemorrhage (13%) were the most common causes of hydrocephalus. The median follow-up period was 47 months (range 6\u2013106 months), and the overall success rate was 68.5% (252 of the 368 procedures). Patients &lt; 6 months of age had a 5-fold increased risk of ETV failure than older patients (adjusted hazard ratio [HRa] 5.0; 95% CI 2.4\u201310.4; p &lt; 0.001). Hemorrhage-related (HRa 4.0; 95% CI 1.9\u20138.5; p &lt; 0.001) and idiopathic chronic hydrocephalus (HRa 6.3, 95% CI 2.5\u201315.0, p &lt; 0.001) had a higher risk of failure than other causes. Most failures (97%) occurred within 2 months of the initial procedure. The overall morbidity rate was 10%, although most complications were minor. Finally, the introduction of ETV in the authors' department reduced the number of shunt insertions and hospital admissions for shunt failures by half and was a source of cost savings.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Endoscopic third ventriculostomy is a safe procedure and an effective treatment option for hydrocephalus. Factors indicating potential poor ETV outcome seem to be very young children and hemorrhage-related and chronic hydrocephalus in adults.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2009.8.peds08108","type":"journal-article","created":{"date-parts":[[2009,12,31]],"date-time":"2009-12-31T16:35:23Z","timestamp":1262277323000},"page":"68-74","source":"Crossref","is-referenced-by-count":127,"title":["Endoscopic third ventriculostomy: outcome analysis in 368 procedures"],"prefix":"10.3171","volume":"5","author":[{"given":"Oumar","family":"Sacko","sequence":"first","affiliation":[{"name":"Service de Neurochirurgie,"},{"name":"Universit\u00e9 Paul Sabatier, Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio","family":"Boetto","sequence":"additional","affiliation":[{"name":"Service de Neurochirurgie,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Lauwers-Cances","sequence":"additional","affiliation":[{"name":"Service d'\u00c9pid\u00e9miologie, Centres Hospitalo-Universitaires de Toulouse; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Dupuy","sequence":"additional","affiliation":[{"name":"Service de Neurochirurgie,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franck-Emmanuel","family":"Roux","sequence":"additional","affiliation":[{"name":"Service de Neurochirurgie,"},{"name":"Universit\u00e9 Paul Sabatier, Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0050068","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"623","DOI":"10.1007\/s00381-007-0335-4","article-title":"Endoscopic third ventriculostomy in children younger than 2 years of age","volume":"23","author":"Baldauf","year":"2007"},{"key":"b2-0050068","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"605","DOI":"10.1007\/s00381-002-0652-6","article-title":"Is the success of endoscopic third ventriculostomy age-dependent?
