Abstract

Coronavirus disease causes a hypercoagulable state with endothelial inflammation. These conditions can produce embolic complications. Thrombosis can occur in different locations and may lead to ischemic stroke and ischemic limb. We report the case of a 64-year-old woman with recent severe acute respiratory syndrome coronavirus 2 pneumonia who was admitted to the hospital due to a giant floating thrombus in the ascending aorta with multiple ischemic events. Aortic computed tomography angiogram revealed an aberrant right subclavian artery associated with bicarotid trunk that might have protected carotid arteries from embol migration. Thrombosis is a rare clinical presentation in coronavirus disease 2019 infection but with serious complications that must be kept in mind to detect and avoid morbidities like ischemic stroke.

Keywords: COVID-19; acute limb ischemia; anticoagulation; aortic disease; arteria lusoria; embolectomy; thrombosis.
