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

ABSTRACT

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 percent the mechanism of trauma was falling; 49.7 percent of the cases had GCS between 13-15; 45.0 percent had skull fractures; 32.8 percent had associated intracranial injuries. Conclusion: We observed that 76.2 percent of surgically treated patients were discharged with minimum or no neurological deficits.
