[Floating thrombus in the aortic arch: a rare case of peripheral arterial embolic events (report of a clinical case)]

Floating thrombus in the aortic arch is a rare and often under-diagnosed source of peripheral arterial embolic events. We report a case of a patient seen with arterial embolic events: ischemia of the left superior limb and transient stroke. The diagnosis was performed with transesophageal echocardiography and computed tomography. The thrombus completely disappeared after 15 days of oral anticoagulant therapy. Although rare, this diagnosis mustn't be overlooked in the search for an etiology of recurrent and disseminated peripheral ischemic events because the detrimental functional risk related to a delayed diagnosis.
