Ommaya Reservoir Placement for Brain Tumor Biomarker Access
The purpose of this study is to determine the safety and feasibility of intra-operative Ommaya Reservoir placement during a clinically indicated operation for brain tumor. The Ommaya reservoir will facilitate a longitudinal access to cerebrospinal fluid (CSF) for analysis of potential biomarkers for brain tumor research and individualized monitoring.
