Acute Aortic Thrombosis Revealing a COVID-19 Infection.

A 75 year old man was admitted with bilateral acute lower limb ischaemia. He had had a coronary artery bypass 15 years ago and remained on antiplatelet therapy. On physical examination, both limbs were ischaemic. Motor function was maintained. The electrocardiogram was normal. Computed tomography scan showed infrarenal aortic thrombosis (A, arrow) with pre-existing asymptomatic atherosclerosis. Systematic pulmonary examination revealed bilateral subpleural areas of ground glass opacification typical of COVID-19 pneumopathy (B, arrows). The polymerase chain reaction was positive. The limbs recovered with intravenous heparin. He was discharged on oral anticoagulants and was evaluated for revascularisation after the lockdown. COVID-19 may have contributed to the thrombosis
