RESUMO
Atheroembolic renal disease is a part of a multisystem disease and can be defined as renal failure secondary to the occlusion of renal arterioles and glomerular capillaries with cholesterol crystal emboli deriving from the aorta and other major arteries. The kidney is usually involved because of the proximity of the renal arteries to abdominal aorta (where the erosion of atheromatous plaque is most likely to occur), and the high renal blood flow. Cholesterol crystal embolism can also occur in other visceral organs, as well as in the upper and lower extremities. Embolization may occur spontaneously or after angiographic and surgical procedures, and anticoagulation. Atheroembolic renal disease is an important yet underdiagnosed component of the spectrum of kidney diseases associated with atherosclerosis and remains an unexplored field of nephrology research.
