Abstract
Object. The aim of this study was to assess the effectiveness of an algorithm used to evaluate and prescribe treatment for patients having slit ventricle syndrome (SVS).Methods. All patients included in this protocol underwent fiberoptic intracranial pressure monitoring after removal or externalization of their ventricular shunt systems. A significant number of patients did not need extracranial cerebrospinal fluid (CSF) diversion and tolerated removal of their shunt systems without requiring further intervention. Patients who demonstrated a need for CSF drainage underwent an endoscopic third ventriculostomy, regardless of the putative cause of their hydrocephalus. Sixteen (72.7%) of 22 patients experienced resolution of or significant improvement in their SVS complaints after their inclusion in the protocol. Concomitantly, 14 (64%) of 22 patients were no longer shunt dependent after a mean follow-up period of 21.4 months.Conclusions. A significant number of patients debilitated by SVS may experience improvement in their symptoms and undergo shunt removal according to this protocol, improving their quality of life and simplifying their medical follow up.
