Abstract
Protruding atheromas in the thoracic aorta are an important cause of embolic disease. Transesophageal echocardiography (TEE) is the modality of choice for diagnosis of these lesions. We present a patient with splenic infarction in whom TEE revealed a large mobile atheroma in the aortic arch. A few hours following the disappearance of this mass from the aortic arch, the patient developed mesenteric artery embolism requiring subtotal small-bowel resection. We discuss the importance of the aortic arch as a source of peripheral emboli and the treatment modalities in these patients.
