[Analysis of prognostic factors in adults with chronic subdural hematoma]

The objective of the study is the analysis of prognostic factors observed in the evolution of 65 patients who presented chronic subdural hematoma surgically evacuated. Morbimortality ratio corresponding to our surgical technique is also presented. A retrospective statistical analysis of epidemiologic, clinic and radiologic factors was performed. Personal background of alcoholism or coagulopathy, decrease of the level of consciousness, a lower score at the Glasgow Coma Score, a maximum thickness of the hematoma superior to 2 cm, and the respiratory and neurologic complications were found to be related to a worst prognosis. Our surgical technique showed 4.6% of mortality and 1.5% of recurrence. Detection of prognostic factors may have important implications in the selection of patients for surgery. Our small craniectomy has similar clinical outcome than other surgical methods.
