Abstract


Background and Objective: Traumatic brain injury (TBI) is a common problem caused by multiple traumas. The TBI patients are clinically evaluated with Glasgow Coma Scale (GCS) as well as imaging methods including computed tomography (CT) scan and magnetic resonance imaging (MRI). According to the GCS scores, patient are divided into three groups: mild (13-15), moderate (9-12) and severe (3-8). This study aims to investigate correlation between GCS and CT-scan findings.

Material and Methods: In this cross-sectional study, a total of 432 patients were evaluated with both brain CT-scan and GCS in their first 24 hours post trauma in the Emam Reza hospital (Kermanshah, Iran) during 2011.

Results: 385 patients (89.12%) were male. Average age of patients was 25 ± 5 (SD) years. The most common causes of TBI were car accidents (72.9%), violence (20.8%) and fallings (6.27%). 70.13% of patients had mild, 7.8% had moderate and 22% had sever TBI. Of all patients, 79.86% cases had positive brain CT, of which 53.47% had subgaleal hematoma and 28.74% extra-axial hematoma as the most common indications.

Conclusion: Findings of this study showed that more than three positive indications including extra-axial, hematoma, subarachnoid hemorrhage, and hemorrhagic contusion are associated with low GCS scores and moderate or severe TBI.
