ABSTRACT
CT angiography (CTA) has demonstrated high degrees of sensitivity and specificity for injuries to both vascular and aerodigestive structures in penetrating neck trauma.(13, 19) Similar series of transmediastinal gunshot wounds that evaluate sensitivity and specificity of CTA through direct comparison with angiography have not been reported. Several reports in the literature have identified CTA as an option to exclude injury if the missile tract can be identified as away from vital structures.(20-22) CTA is followed by biplanar arteriography if major arterial structures demonstrate evidence of injury or are deemed to be at risk based on missile tract.
