Recurrent floating common carotid artery thrombus related to COVID-19: A case report.

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.

We report here a case of aorto-cava fistula complicating the rupture of a sub-renal aortic aneurysm into the inferior vena cava, which is a rare complication of aortic abdominal aneurysms with often-fatal outcome. Abdominal computed tomography with multi-planar reconstructions remains the firstline-imaging tool allowing positive diagnosis and preoperative planning. Treatment may be surgical or endovascular.
