“…The most common embolic site is the lower extremity artery, with the next most common sites being the mesenteric and renal arteries. The rarest embolic sites are the cerebral and coronary arteries, but these were often the most lethal and seriously affected the prognosis [9,10]. Toyama et al believed that the risk of thromboembolism is related to the size of the aortic thrombus base and the degree of calcification, but not to the location of attachment or volume of the thrombus [11].…”

Background A floating thrombus in an ascending aorta with normal morphology is very rare, but when it does occur, it may induce a systemic embolism or fatal stroke. The pathophysiological mechanisms of aortic mural thrombi remain unclear, and there is no consensus regarding therapeutic recommendations. Case presentation We report a 49-year-old male who presented with chest discomfort for 5 days and was admitted to our emergency unit. A contrast-enhanced computed tomography angiography (CTA) surprisingly demonstrated a large filling defect suggestive of a thrombus in his otherwise healthy distal ascending aorta. Surgical resection of the mass and attachment site was performed. Histological examination confirmed that the mass was a thrombus, but the cause of the thrombus formation was unknown. Conclusions floating aortic thrombi are rare, and they are prone to break off, thus carrying a potential risk for embolic events with catastrophic consequences. Surgical resection, both of the aortic thrombus and attachment site, as well as postoperative anticoagulant administration, are standard treatments.
