Topic: Acute aortic thrombosis presenting as acute limb ischemia in two young, non-atherosclerotic patients

Abstract

Mobile aortic thrombus (MAT) in a normal aorta is a rare entity with majority (up to 82.4 per cent) of cases diagnosed only after an arterial embolic event. Cardiac sources or proximal aortic disease account for 90 per cent of peripheral arterial embolic events and it is rare for the non-aneurysmal aorta to contribute to these embolic events. A normal cardiac evaluation coupled with lack of smoking history and atherosclerotic risk factors, should trigger further evaluation for Mobile Aortic Thrombus and pro-thrombotic causes in young patients. In this current pandemic, we have also increasingly recognise COVID-19 infection as a cause for mobile aortic thrombus. We describe our experience in treating acute lower limb ischaemia secondary to mobile aortic thrombus.
