Refractory Thoracolumbar Cerebrospinal Fluid Leak after Multiple Spinal Ependymoma Resections Treated with External Ventricular Drainage

Abstract

Study Design Case report. Objective Temporary external ventricular drainage for refractory thoracolumbar cerebrospinal fluid (CSF) leak is not reported in the literature. We describe a recent case that utilized this technique. Methods Retrospective review of the patient's case notes was performed and the literature on this subject reviewed. Results The patient underwent multiple complex spinal surgeries for resection of innumerable metastatic ependymoma lesions. A case of significant refractory CSF leak developed and as a last resort a right frontal external ventricular drain was placed. The CSF leak ceased, and the patient was eventually discharged home without further complication. Conclusion External ventricular drainage can be a viable option for temporary proximal CSF diversion to treat refractory thoracolumbar CSF leaks.
