Values of cerebrospinal fluid cytochemistry in pediatric patients with ventriculoperitoneal shunt

Background: The ventriculo-peritoneal shunt (VPS) is the treatment for hydrocephalus, the cerebrospinal fluid (CSF) is evaluated for the management of its complications; however, information on the values of the cytochemistry in this population is insufficient. Aim: To describe the characteristics of the CSF cytochemistry of children in VPS management. Methods: Descriptive observational study, developed in Bogota (Colombia), from 2008 to 2016. VPS and related procedures records were reviewed. Patients between 6 months and 18 years were included. Results: A total of 285 records were reviewed, 31 samples were entered. The CSF values were, respectively, for the median and 90% percentile: total leukocytes: 0 and 7 cells/mm(3), neutrophils: 0 and 6.8 cells/mm(3), lymphocytes: 0 and 2 cells/mm(3), proteins: 13.4 and 67.2 mg/dL, glucose: 59 and 27.4 mg/dL. Discussion: Glucose values evinced a normal rank towards the widest inferior limit with protein values exceeding the values expected. Cellularity is the variable with the lowest variation. Conclusions: The values of the CSF cytochemistry in patients with VPS are not comparable to those of the healthy population and should be interpreted according to the characteristics of this population.
