Podcast 543: Scoring Blunt Traumatic Aortic Injury

Podcast 543: Scoring Blunt Traumatic Aortic Injury

Author: Nick Tsipis, MD

Educational Pearls:

  • Aortic injury caused by blunt trauma is very rare
  • Chest x-ray findings might include widening of the mediastinum
  • Ligamentum arteriosum (remnant of the ductus arteriosus) tethers the aorta to the chest wall, potentially causing injury with abrupt decelerations and motion
  • XR lacks significant sensitivity (around 75%) to be utilized in many cases
  • CT angiogram (CTA) of the chest is typically the preferred test but comes with potential risks including radiation exposure
  • NEXUS Decision Instrument (NEXUS DI) is a scoring tool that may provide value in determining the need for additional imaging
