CTICasesTraumatic Stanford Type B Aortic Dissection
Imaging findings
CT angiogram shows a Stanford Type B aortic dissection starting at the isthmus and extending all the way into the abdominal aorta, complicating blunt deceleration trauma (bicycle struck by a car) with associated rib fractures.
Key takeaways
While blunt aortic injuries typically cause focal lacerations/pseudoaneurysms, they can occasionally present as a classic, long-segment aortic dissection (Type B), particularly in patients with deceleration trauma.
