Abstract:
We describe an uncommon presentation of severely advanced aortic atherosclerosis in a 48-year old man with a history of hypertension and heavy smoking. Initial presentation with upper limb ischaemia led to the diagnosis of an aortic arch atheroma occluding 90% of the aortic lumen, managed with deep hypothermic circulatory arrest and aortic thromboendarterectomy. To our knowledge, this is the first reported case of atherosclerotic plaque resulting in aortic occlusion and requiring emergent operative intervention.
