BackgroundThis study aims to investigate the clinical outcomes of patients who underwent closed continuous lumbar drainage (CLD) for post-traumatic cerebrospinal fluid (CSF) fistula and to compare with those of non-traumatic patients.MethodsThe data of patients who were treated in the department of neurosurgery between January 2018 and December 2019 and underwent CLD were analyzed. The diagnosis, demographic characteristics, CSF results and clinical outcomes of these patients were evaluated. The outcomes of the patients with dura defect and CSF fistula due to trauma were compared with patients who underwent CLD for other diagnoses.ResultsIn this study, 45 patients underwent CLD for 51 times. The mean age was 38.84 years, and 27 (60%) of the patients were male. Seven (15.55%) patients underwent CLD due to post-traumatic CSF fistula and 38 patients after tumor or malformation surgery. While five patients developed CSF fistula due to dura defect after gunshot injury, two patients developed CSF fistula secondary to motor vehicle accident. Staphylococcus Epidermidis was isolated in one patient among post-traumatic CSF fistula patients while Serratia Marcescens was isolated in patients with CSF fistula secondary to posterior fossa tumor surgery. While none of the seven patients died during the follow-up period in post-traumatic group, one of the 38 patients with CLD secondary to tumor surgery was lost due to sepsis in the follow-up period.ConclusionCLD in post-traumatic CSF fistulas is a safe and effective treatment method. Especially in patients with gunshot wounds, CLD should be performed before revision surgery in the treatment of CSF fistula. Studies with different parameters are needed in larger trauma populations.
