The role of computed tomography angiography in the detection of aerodigestive tract injury following penetrating neck injury

摘要

Background: The purpose of this study was to audit our experience with computed tomography angiography (CTA) for the detection of aerodigestive tract injury (ADTI) following penetrating neck injury (PNI) and to assess the significance of deep surgical emphysema on CTA. Methods: A prospectively maintained trauma registry at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa was retrospectively interrogated. The data of all patients with PNI investigated with CTA over a 4-y period were reviewed. All findings of deep surgical emphysema were correlated to an aggregate standard of reference for ADTI as demonstrated by results from clinical examination, surgical neck exploration, endoscopy or contrasted swallow to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of this finding.
