What mechanisms are commonly associated with thoracic aortic rupture?
Motor vehicle accidents - unrestrained drivers/passengers, pedestrians struck by motor vehicles, falls from height (>10 feet)
Conclusion:
- Traumatic aortic injury is evident with a contained rupture on the undersurface of the aortic arch, at the attachment of the ligamentum arteriosum.
- Fractured left second through eighth ribs.
- The upper fractures are segmental and there is displacement of the third rib into the lung.
- Adjacent pulmonary contusion and atelectasis.
- Mild right lung atelectasis. Moderate sized left pneumothorax
