Background: Suitable maintenance of cerebral perfusion is important to prevent further brain damage, and previous studies have emphasized an influence of bran ischemia on traumatic brain injuries (TBI). ABCD2 score and CHADS2 score are available for predicting subsequent ischemic events of brain. In this study, we investigate whether these stroke risk scores are useful to predict neurological deterioration of TBI.

Methods: 452 patients with TBI were admitted to our hospital from Oct. 2007 to Mar. 2012. Patients with chronic subdural hematoma, and with low ADL were excluded from this investigation. Finally 272 cases were enrolled in this study. ABCD2 score, CHADS2 score and modified Rankin scale (mRS) of these patients were evaluated.

Results: Patients with ABCD2 score of 1 and over demonstrated poor neurological prognosis. But a correlation between ABCD2 score and mRS are not found. CHADS2 score has a significant correlation with neurological prognosis of TBI. Patients with CHADS2 score of 2 and over demonstrated poor prognosis (mRS 3 – 6). And patients with CHADS2 score of 4 and over demonstrated high mortality rate.

Conclusion: CHADS2 score is useful to predict a neuro­logical prognosis of TBI.
