Cholesterol Embolism

Cholesterol emboli are a common complication of advanced atherosclerotic disease. Cholesterol crystals dislodged from plaques through the circulation until they become trapped in smaller vessels, which leads to ischemia and infarction. Histological confirmation is made by biopsy of the target organs, which include kidneys, muscle, and skin.
