Cholesterol Emboli Syndrome

Cholesterol Emboli Syndrome is a condition where tiny pieces of cholesterol break off from large arteries and travel through the bloodstream. These cholesterol fragments can block small blood vessels in various organs, most commonly the skin, kidneys, and digestive system. This blockage can cause symptoms like painful skin changes, kidney problems, and abdominal pain. The condition mainly affects the circulatory system and can lead to serious complications if multiple organs are involved. It often occurs after procedures involving arteries or in people with severe atherosclerosis. The syndrome can cause a range of health issues depending on which organs are affected by the cholesterol blockages.

Cholesterol Emboli Syndrome (CES) is a systemic disorder caused by the embolization of cholesterol crystals from disrupted atherosclerotic plaques in large arteries, typically the aorta. These cholesterol emboli occlude small arterioles and capillaries, leading to tissue ischemia and inflammation. CES commonly occurs after vascular interventions such as angiography, vascular surgery, or anticoagulation therapy, which destabilize plaques. The syndrome is characterized by a triad of livedo reticularis, acute kidney injury, and eosinophilia. It is a form of vasculitis-like microvascular occlusion with secondary inflammatory response. CES is clinically significant due to its potential to cause multi-organ dysfunction and high morbidity.
