Epidemiological analysis of 189 cases of traumatic intracranial extradural hematoma treated by surgery. Análisis epidemiológico de 189 casos de hematoma epidural tratados quirúrgicamente

Objective: To analyze the epidemiology, clinical and radiological presentation of patients with extradural hematoma (EDH) who underwent surgery in our service and their neurological status at the time of discharge. Method: we reviewed the charts of 189 patients who were admitted to our service with EDH and were treated surgically, during the period of August 1998 to January 2007. Results: In 49,2% the mechanism of trauma was falling; 49,7% of the cases had GCS between 13-15; 45,0% had skull fractures; 32,8% had associated intracranial injuries. Conclusion: we observed that 76,2% of surgically treated patients were discharged with minimum or no neurological deficits.
