Résumé
The occurrence of arterial and venous thrombosis during coronavirus infection has been widely reported since the beginning of the epidemic. Floating carotid thrombus (FCT) in the common carotid artery is exceptional and its main known cause is atherosclerosis. We describe the case of a 54-year-old man who developed, one week after the onset symptomatology of related to COVID-19 infection, an ischemic stroke, complicating a large intraluminal floating thrombus in the left common carotid artery. Despite surgery and anticoagulation, a local recurrence with other thrombotic complications occurred and the patient died.

Carotid free-floating thrombus is an uncommon entity that usually presents with neurologic symptoms. Crescendo transient ischemic attack is an accepted indication for urgent carotid endarterectomy. COVID-19 is associated with severe thromboembolic complications. We report the case of a 61-year-old man who developed, 2 weeks after the diagnosis of COVID-19, crescendo transient ischemic attack, complicating a large intraluminal floating thrombus within the right common carotid artery. A carotid thromboendarterectomy under local anesthesia, with patch closure was immediately performed without complications. We conducted a literature review to identify cases of common carotid artery thrombus related to COVID-19. Carotid free-floating thrombus in the common carotid artery is exceptional. However, since the beginning of the COVID-19 pandemic, 15 cases have been published.
