In the present study, we evaluated the association of the Glasgow Coma Scale (GCS) score and amount of blood loss with mortality in patients presenting with traumatic acute subdural hematoma (ASDH).


This retrospective study was performed on 99 patients who were operated for traumatic acute subdural hematoma (ASDH) without any systemic association at a single center. Epidural hematoma was reported to be the most common additional pathology. Age, sex, mechanism of trauma, time interval between onset of trauma and admission to the emergency ward, associated problems, thickness of hematoma and Glasgow Coma Scale (GCS) score at the time of admission and on discharge were all studied.


The GCS score was inversely proportional to the thickness of hematoma and interval between onset of trauma and surgery (p < 0.05). Although the mortality rate was reported to be high in traffic accidents, the rate was low in patients with head trauma only (p < 0.05). The mortality rate was high in patients with associated pathologies (p < 0.05). Lost patients were reported to be older patients with more extensive ASDH or those who presented earlier with a low GCS (p < 0.05).


ASDH is associated with high mortality. GCS score and the thickness of the ASDH are important predictors of mortality. Age, additional trauma, and interval between trauma and hospital admission are major predictive factors for mortality.
