Abstract

Objective
Chronic subdural hematoma is relatively common brain injury in the geriatric patients. We evaluated the independent association between pre-operative CT findings in chronic subdural hematoma and Glasgow outcome score at discharge as a measure of outcome.
Methods
Total fifty-eight consecutive patients with chronic subdural hematoma presented to our institution from January 2005 to March 2011. Their Glasgow coma scale range at the admission was thirteen to fifteen. The variable considered were brain atrophy, hydrocephalus and hematoma density.
Results
Brain atrophy and high hematoma density were significant association with unfavorable outcome (p<0.01, p=0.03).
Conclusion
Brain atrophy and high hematoma density were independently increase the risk of unfavorable outcome after chronic subdural hematoma. In the geriatric patients with chronic subdural hematoma, pre-operative CT scanning might be predicts the unfavorable outcome.
