BackgroundSubdural hematoma (SDH) is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes.ObjectivesTo determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma.Materials And MethodsWe retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery.ResultsForty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005), yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44%) were discharged home, 16 (36%) discharged to nursing home or rehab, 6 (13%) to hospice and 3 (7%) died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed.ConclusionSurgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.
