CTICasesTraumatic Aortic Injury (Type 1 and Type 3 Tears)
Imaging findings
Contrast CT chest in a patient with blunt chest trauma reveals two separate aortic injuries: a classic type 3 traumatic aortic transection/injury at the aortic isthmus, and a separate, smaller type 1 intimal tear proximal to the isthmus.
Key takeaways
Blunt chest trauma can cause simultaneous multi-level aortic injuries, such as a major type 3 disruption at the isthmus combined with a proximal type 1 intimal tear. Recognizing minor intimal tears is critical as they may be managed conservatively, whereas type 3/4 injuries require urgent intervention (e.g., endovascular stenting).
