Successful removal of a floating thrombus in ascending aorta

Abstract

Free-floating thrombus in ascending aorta is a rare cause of peripheral embolism with potentially fatal consequences. We report the case of a young patient with syncope and sudden lumbar pain. Computed tomographic scan revealed a large pedunculated floating mass attached to the posterior wall of the ascending aorta, probably responsible of renal embolic infarction; transthoracic echocardiography confirmed the diagnosis. Surgery was urgently performed. The thrombus was excised, and was not related to atherosclerotic disease of the aortic wall. We conclude that once diagnosis is clear, urgent surgery must be considered to avoid any further embolic complications.
