An acute lower limb ischemia revealing a covid-19 infection: A case report.

Covid-19 is associated with thrombo-embolic events. These complications are either veinous or arterial. By this case report, we aim to highlight the physiopathology and the epidemiology of covid-19 related thromboembolic complications. We report a case of a 65 years old patient who was admitted fo lower limb ischemia complicating a covid-19 infection. Computed tomography of the aorta and lower limbs showed thrombosis of the femoral artery extended to the popliteal artery and leg arteries. Despite a surgical embolectomy the patient rethromboses twice leading to a thigh amputation. Several hypotheses have been put forward to explain Covid 19-related thromboembolic events. About 3% of patients develop arterial thrombosis. Raffaello Bellosta and al. reported the incidence of acute limb ischemia has significantly increased during the COVID-19 pandemic in the Italian Lombardy region. The coagulopathy responsible for venous and arterial thrombosis is a well-established complication of COVID-19. Arterial thromboembolic complications can be either stroke, acute coronary syndrome or peripheral acute ischemia. Therefore, patients with covid19 should be monitored more closely for thromboembolic complications.
