Contusion Contrast Extravasation Depicted on Multidetector Computed Tomography Angiography Predicts Growth and Mortality in Traumatic Brain Contusion.

摘要: Traumatic brain injury (TBI) is the main cause of death in trauma victims and causes high rates disability neurological sequelae. Approximately 38-65% traumatic contusions (TBC) demonstrate hemorrhagic expansion on serial computed tomography (CT) scans. Thus far, however, no single variable can accurately predict hemorrhage a TBC. Our purpose was to evaluate contrast extravasation (CE) as predictor expansion, mortality, poor outcome TBC Brazilian cohort. After Institutional Review Board approval, we used multidetector CT angiography (MDCTA) study 121 consecutive patients (106 men, 87.6%) with ages varying from 10 85 years. Informed consent obtained all subjects. The clinical imaging findings were correlated initial MDCTA using either Fisher exact test or Student t multivariate logistic regression model. Of persons who presented CE TBC, 21.8% died (in-hospital mortality), whereas absence this sign, mortality rate 7.6% (p = 0.014). In addition, component detected 61.1% CE-positive patients, only observed 10% CE-negative (p < 0.001). Poor 24.2% group, but presence CE, 72.7% evolved strong independent outcome, increased risk in-hospital our series
