| Abstract |
|
Cholesterol embolism, a complication of ulcerous atheroselerosis, is a pathologic process of small arteries in many organs of the body by cholesterol cystals, causing a multiple-system disease. Cholesterol embolism is to be differentiated from atheroembolism, the other type of atheromatous embolism, which results in the obstruction of a large artery in one organ. Also it should be distinguished from vasculitis, connective tissue dis- ease or infective endocarditis which causes multiple system dysfunction. Cholesterol embolization can occur spontaneously but usually develops as a complication of vascular procedures. As the invasive vascular procedures such as arteriography or angioplasty have been used popularly for a diagnostic or therapeutic purpose, cholesterol embolization is expected to occur in patients with high- risk factors for atherosclerosia We report two cases of cholesterol embolization as- sociated with renal failure and gangrene of the lower extremities after coronary angiography, proven by renal biopsy. |
