CTICasesTraumatic aortic root rupture and coronary artery dissection
Imaging findings
Gated CT of a motor vehicle accident patient shows a traumatic aortic root rupture/intimal tear near the right coronary cusp, and a dissection flap extending into the left main and LAD coronary arteries, causing severe myocardial ischemia.
Key takeaways
Blunt chest trauma can cause catastrophic injuries at the aortic root, including coronary artery dissection. ECG-gated CTA is essential to evaluate the aortic root and coronary ostia when patients present with post-traumatic ischemia or troponin elevation.
