ABSTRACT
The authors analyzed 39 patients with huge epidural hematoma following craniocerebral trauma. Multiple factors such as bleeder, Glasgow Coma Score, hematoma site and its' volume, midline shift, and associated traumatic lesion on initial CT scan appear to expert bad outcome. The initial CT scan findings on admission were assessed and the results obtained are as follows. 1) The outcome harboring huge epidural hematoma is bad in 28% of total 39 patients. 2) The main bleeder is varied in origin according to the hematoma site. 3) The temporo-parietal epidural hematoma affects significantly the Glasgow Coma Scale(GCS) and the patient's outcome, compared with those of frontal and occipital area. 4) The patient's outcome is closely related to the hematoma volume, especially over 16% of total brain volume. 5) The midline shift over 15mm suggests the bad outcome, especially in temporo-parietal epidural hematoma.
