Highest maintained patency rate is with previously untreated acquired AqS. The success rate in infants may be poor because they may not have a normally developed subarachnoid space. There is a low success rate (only ≈ 20% of TVs will remain patent) if there is pre-existing pathology including: 1. tumor 2. previous shunt 3. previous SAH 4. previous whole-brain radiation (success with focal stereotactic radiosurgery is not known) 5. significant adhesions visible when perforating through the floor of the third ventricle at the time of performance of ETV ---- Also in the elderly, [[Endoscopic third ventriculostomy]] is a safe and efficient procedure, with success rates similar to the younger population. Further research is required to set up a prognostic scoring system for this age group ((Niknejad HR, Depreitere B, De Vleeschouwer S, Van Calenbergh F, van Loon J. Results of endoscopic third ventriculostomy in elderly patients ≥65 years of age. Clin Neurol Neurosurg. 2015 Mar;130:48-54. doi: 10.1016/j.clineuro.2014.12.009. Epub 2014 Dec 31. PubMed PMID: 25576885.)). ---- A repeat [[endoscopic third ventriculostomy and choroid plexus cauterization]] can be an effective salvage therapy in the event of ETV failure ((Kono M, Tsuda K, Yamashita M, Ihara S. Repeat [[endoscopic third ventriculostomy]] combined with [[choroid plexus cauterization]] as [[salvage surgery]] for failed endoscopic third ventriculostomy.
