Atheroembolism is defined as microembolism of atherosclerotic and fibrotic debris from the aorta or proximal limb arteries to small arteries of the limbs or other organs. Atheroembolism occurs most often in patients over 50 years of age, the age group most affected by atherosclerosis. It may occur spontaneously or subsequent to dislodgment of atherothrombotic debris by catheters used in diagnostic or therapeutic procedures. Occlusion of the vessels of the digits and skeletal muscles causes signs of ischemia despite the presence of palpable pulses. Renal failure may occur if atheroemboli lodge in the renal vasculature.
Treatment includes a platelet inhibitor to reduce the risk of recurrent atheroembolism.
It is not known whether warfarin prevents or causes atheroembolism. In patients with an obvious source of atheroembolism, such as abdominal aortic aneurysms, surgical removal or exclusion of the source from the circulation is indicated. Digital necrosis and gangrene require amputation. Make sure you get the best price. All rights reserved.
