Clinical Outcome of Patients Diagnosed Traumatic Intracranial Epidural Hematoma With Severe Brain Injury (Glasgow Coma Scale ≤8) Who Undergo Surgery: A Report From the Korean Neuro-Trauma Data Bank System

Objective: To evaluate the clinical outcomes and prognostic factors in surgically treated patients with severe brain injury (Glasgow Coma Scale [GCS] score ≤8) diagnosed with traumatic epidural hematoma (EDH). Methods: From January 2018 to June 2021, 1,122 patients with an initial GCS score ≤8 were retrospectively enrolled in the Korean Neuro-Trauma Data Bank System. Clinical data of 79 surgically treated patients with EDH were compared between the unfavorable (scores of 1-4 on the Glasgow Outcome Scale-Extended [GOSE]) and favorable (score of 5-8 on the GOSE) outcome groups. Results: =0.002) were the most significant risk factors in the multivariate logistic regression analysis. The interval from admission to the brain CT scan was not correlated with the outcome; however, it was significantly longer in the unfavorable outcome group. Conclusion: Despite severe brain injury, more than half of the patients with EDH had favorable outcomes after surgical treatment. Our findings suggest that prompt diagnosis and surgical treatment should be considered for such cases.
