Treatment of ventriculoperitoneal shunt dysfunction during rehabilitation therapy in patients with normal pressure hydrocephalus

Abstract

This report describes the effects of a programmable pressure-controlled valve shunt system (PVSS) for ventriculoperitoneal (V-P) shunt dysfunction, e.g. overdrainage, during rehabilitation therapy of two stroke (subarachnoid or intra-cerebral hemorrhage) patients with normal pressure hydrocephalus (NPH). The effects were superior to those in two other NPH patients who received a V-P shunt with a fixed valve-pressure system. The V-P shunt with PVSS was useful to treat non-invasively the functional overdrainage and slit ventricle syndrome that some patients experienced in the rehabilitation ward.
