Abstract:
OBJECTIVE: The purpose of this study was to evaluate the factors that influence to chronic subdural hematoma recurrence. METHODS: We retrospectively evaluated 55 patients who underwent an operation for a chronic subdural hematoma using burr hole trephination and hematoma drainage from January 2010 to December 2011. We analyzed their demographics, trauma history, medication history, initial symptoms, bilaterality, postoperative pneumocephalus, and hematoma recurrence. RESULTS: Medication history (anticoagulant and/or antiplatelet agents) was not influenced the hematoma recurrence rate statistically (p=0.622). Prolongation of International Normalized Ratio and decrease of platelet count increased recurrence rate, but not significantly. An absence of trauma history was a factor that significantly influenced hematoma recurrence (p=0.037). CONCLUSION: Medication history did not significantly influence the recurrence rate, if the medication will stopped more than 3 days prior to hematoma evacuation. Chronic subdural hematomas that occurred without definite trauma history were more prevalent with recurrence.
