Context: Only few comprehensive studies have investigated acute epidural hematoma (AEDH),
and a low incidence of the lesion has been observed in comparison with other types
of traumatic brain injuries such as subdural hematoma, traumatic subarachnoid hemorrhage,
and contusion. Aim: This study aims to identify the prognostic factors of surgically treated AEDH. Settings and Design: The medical records of 58 consecutive patients with surgically treated AEDH between
September 2011 and 2018 were retrospectively reviewed. Subjects and Methods: All patients were diagnosed with AEDHs using 5-mm-slice computed tomography (CT).
Information regarding the following demographic and clinical characteristics was collected:
age, sex, antithrombotic drug use, mechanisms of injury, time from onset to operation,
neurological examination, vital signs, blood examination, and CT findings. Statistical Analysis Used: We analyzed prognostic factors in patients with AEDH using univariate and multivariate
regression analyses. Results: Univariate and multivariate regression analyses revealed that age (P < 0.01) and
the Glasgow Coma Scale (GCS; P < 0.01) were independent predictive factors for good
prognosis. In addition, receiver operating characteristics (ROC) analysis showed that
an age of <55 years and a GCS score of >12 were optimal cutoff values for predicting
good prognoses, with the areas under the ROC curve of 0.827 and 0.810, respectively.
Conclusions: Age and GCS are useful predictors of prognosis in patients with surgically treated
AEDH. These findings are appropriate prognostic indicators for urgent surgery performed
to treat AEDH and intended to help clinicians make a prompt diagnosis.
