Introduction: Traumatic acute subdural hematoma (TASDH) is by far the most common traumatic brain injury in elderly patients presented to the emergency department, and a number of those treated conservatively will develop chronic subdural hematoma (CSDH). The factors contributing to chronicity were not well studied in the elderly; therefore, we retrospectively analyzed our elderly patients with acute subdural hematomas to identify the risk factors which might contribute to the development of subsequent CSDH.
Methods: A retrospective analysis of 254 patients with TASDH admitted between 2012 and 2016 to our level 2 trauma department in a community hospital was collected.
