An Effective and Less Invasive Treatment of Post-Traumatic Cerebrospinal Fluid Fistula: Closed Lumbar Drainage System

Abstract

Cerebrospinal fluid (CSF) leakage may develop when a defect is formed in dural layers by traumatic or iatrogenic processes. Traumatic CSF leakage was encountered in 2% of head injuries. CSF leakage is an associated feature of 12-30% of skull base fractures. Numerous treatment modalities are proposed for the management of CSF leaks. A closed lumbar drainage system (CLDS) is recommended as an alternative method to surgery for preventing complications related to leakage. In the present study, we report the clinical details of 46 patients who suffered from rhinorrhea/otorrhea (R/O), three of whom were urgently operated due to other causes like subdural hematoma and tension pneumocephalus. Leakage spontaneously ceased in 26 (60.4%) patients whereas CLDS insertion was found to be necessary in 17 patients. A prophylactic antibiotic regimen was started in the CLDS group and these patients were followed with daily CSF cell counts. Fifteen patients (88.2%) were successfully treated by CLDS, however meningitis developed in 2 patients (11.7%). Severe complications like meningitis could be avoided by a simple daily microbiological analysis of CSF.
