CTICasesTraumatic Aortic Injury with Subclavian Dissection
Imaging findings
CT angiography shows a traumatic aortic pseudoaneurysm located proximally in the aortic arch, associated with circumferentially dissecting intramural hematoma extending into the left subclavian artery.
Key takeaways
Blunt chest trauma can cause traumatic aortic injury. While classically occurring at the aortic isthmus, injuries can locate more proximally in the arch. Circumferential hematoma can extend into the branch vessels (such as the left subclavian), complicating endovascular repair.
