Abstract

To provide a simple and reliable method for the diagnosis of ventriculoperitoneal shunt malfunction.A total of 14 participants were enrolled in this study, consisting of 7 patients with suspected shunt malfunction and 7 control cases with apparent normal drainage. In all cases, 0.1 mL of 5% glucose solution was injected into the reservoir and 0.1 mL of cerebrospinal fluid was withdrawn from the reservoir 20 minutes later to measure glucose concentration.The glucose concentration in cerebrospinal fluid of the shunt malfunction group was greater than that of the control group (P < 0.05).The proposed method is reliable, safe, and relatively simple for the diagnosis of ventriculoperitoneal shunt malfunction and provides a reference for treatment.
