Hydrocephalus is commonly treated with a shunt, a tube typically containing one or more valves to manage the amount of cerebrospinal fluid (CSF) it removes from the ventricles or other fluid spaces in or about the central nervous system. The shunt is usually described by the space its inlet(s) drain (e.g., ventricular) and the space into which it deposits the CSF (e.g., peritoneal) to treat the hydrocephalus (e.g., ventricular-peritoneal, ventriculo-peritoneal shunt or VP shunt).
