CTICasesMinimal Aortic Injury
Imaging findings
CT angiography in a trauma patient shows a focal, minimal intimal tear and a tiny adherent thrombus in the distal descending thoracic aorta, without a pseudoaneurysm, contour abnormality, or mediastinal hematoma.
Key takeaways
Minimal aortic injuries (MAI) represent intimal tears or small thrombi without aortic contour deformity. Unlike severe aortic ruptures, MAIs are typically managed conservatively with heart rate and blood pressure control and show high rates of spontaneous resolution on follow-up CT.
