CTICasesBlunt Aortic Injury (Grade 3)
Imaging findings
CT in a 25-year-old post-MVC shows a pseudoaneurysm and intimal tear of the descending thoracic aorta (Grade 3 blunt aortic injury). Repair was delayed due to severe traumatic brain injury contraindicating anticoagulation.
Key takeaways
Grade 3 blunt aortic injury (pseudoaneurysm) is typically treated with TEVAR. However, in patients with severe traumatic brain injury, the risk of systemic anticoagulation required for stent placement must be balanced against the risk of aortic rupture.
