Abstract

Introduction: The relationships between Glasgow Outcome Scale (GOS), Glasgow Coma Scale (GCS) and brain computerized tomography (CT) with unilateral chronic subdural hematoma (CSDH) are not consistent in studies.
Methods: Between Oct 2005 to March 2009, 93 unilateral CSDH patients (mean age 71±11 years) were enrolled for analysis. The associations between GOS at discharge and the following variables on admission including sex, age, GCS, time interval from injury to emergency room, hematoma site, hematoma thickness, hematoma density, midline shift, ventricular sizes (Evan's index and maximum diameter of third ventricle-3Vmax. D), and cortical atrophy on brain CT were evaluated.
Results: By multiple logistic regression statistics, the adjusted odds ratio (OR) in predicting the poor outcome was significant with GCS <15 [OR=11.2, CI=1.3-96.9, p=0.028] and mixed density hematoma on brain CT [OR=7.4, CI=1.8-31.7, p=0.007]. Using Receiver-Operating Characteristic (ROC) curve, the sensitivity was 73% and the specificity was 85%.
Conclusions: In our preliminary study that mixed hematoma density and lower GCS were associated with poor prognosis in unilateral CSDH with sensitive prediction.
