Abstract

|
ObjectivesThe purpose of this study was to analyze risk factors related to prognosis in patients treated for isolated traumatic acute subdural hematoma (ASDH).
Methods:A retrospective study of 164 blunt head trauma patients with isolated ASDH who were admitted to our hospital between January 2002 and December 2009 were reviewed. Information regarding age, sex, trauma mechanism, Glasgow Coma Scale (GCS) score, symptoms, brain computed tomography (CT) findings, hospital course and 6-months outcome were collected and analyzed.
Results:The overall mortality was 19.6% (32/164). A lower GCS score at the time of admission, the presence of brain herniation were identified as independent risk factors, while no independent association was observed between mortality and hematoma volume, thickness, midline shift and obliteration of patency of the basal cisterns, although these variables were correlated with mortality in univariate analyses.
Conclusion:These findings can be used to predict outcome and may also be useful in making decisions about triage, quality assurance, and improve survival.
