INCIDENCE OF ACUTE LIMB ISCHEMIA IN COVID POSITIVE PATIENTS IN RGGGH, CHENNAI

Abstract

Acute Limb Ischemia is dened as any sudden decrease in limb perfusion causing potential threat to limb viability. It can be caused by embolism or thrombosis. Commonly affects arteries of lower extremities. The risk factors for ALI can be multifactorial. The commonest include embolic predisposition like atrial brillation or coronary artery disease, trauma or thrombosis due to atherosclerosis or hypercoagulable state like malignancy, leukemia, Antiphospholipid syndrome, protein C /S/ antithrombin deciency, polycythemia vera, thrombocytosis. Thrombosis of a bypass graft is common in western countries which occurs at the site of anastamosis. A sudden and signicant increase of COVID-19–infected patients who were presenting with ALI has been noted at our institutions recently. A prothrombotic state, is present in patients with severe COVID-19 illness, where increased brin and brin degradation products are noted. This has been shown to adversely increase the severity of ALI and affect outcomes
