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.
颈内动脉游离血栓是一种不常见的实体，通常表现为神经症状。递增性短暂性脑缺血发作是紧急颈动脉内膜切除术的公认适应证。COVID-19 与严重的血栓栓塞并发症相关。我们报告了一例 61 岁男性的病例，他在 COVID-19 诊断后 2 周出现递增性短暂性脑缺血发作，右颈总动脉内腔内出现大的漂浮性血栓。在局部麻醉下立即进行颈动脉血栓内膜切除术，并采用补片修补，无并发症。我们进行了文献回顾，以确定与 COVID-19 相关的颈总动脉血栓形成的病例。颈总动脉内游离血栓极为罕见。然而，自 COVID-19 大流行开始以来，已经发表了 15 例病例。
