Complex aortic atheroma is a high-risk factor for recurrent embolic stroke. An accurate identification of stroke etiology

 

Abstract

Complex aortic atheroma is a high-risk factor for recurrent embolic stroke. An accurate identification of stroke etiology is clinically important; however, it can be challenging. A 91-year-old man with atrial fibrillation was diagnosed with cardioembolic stroke and treated with mechanical thrombectomy. The removed thrombus microscopically contained foamy cells, suggesting an atheroembolism. An autopsy revealed an atherosclerotic lesion with ulceration, located in the aortic arch. At the lesion, the plaque had microscopically ruptured into the lumen. We therefore concluded that the aortic atherosclerotic lesion was the embolic source. Removed thrombi should be pathologically examined even if a cardioembolic stroke is clinically suspected.
