Not to be confused with nontraumatic thoracic aortic dissection
Background
- Blunt traumatic mechanism, rapid deceleration
- Pt often asymptomatic but die w/o warning (80% die at scene)
- Hypotension NOT from ruptured aorta (just die)
- Need high suspicion to diagnose
Diagnosis
- CXR
- Widened mediastinum(>8cm on supine film)
- CT
- Diagnostic study of choice
- Good for aorta but not for branch vessels
- Aortography
- Gold standard
- 25% have complications (i.e. infection & hematoma)
- No longer routinely performed
Differential Diagnosis
Thoracic Trauma
- Airway/Pulmonary
- Cardiac/Vascular
- Musculoskeletal
- Other
Treatment
- Initial medical management similar to Nontraumatic thoracic aortic dissection
- Keep SBP <120, HR 60-80 w/ alpha/beta blockers, CCBs
- Surgical management for high grade injuries
