title: [Livedo reticularis, acral necroses and renal failure. Cholesterol crystal embolisms].
abstract: In a 67 year old patient with multiple cardiovascular risk factors a livedo reticularis, ischemic acral lesions as well as deterioration of renal function five weeks after cardiac catheterism and aorto-coronary bypass surgery led to suspicion of cholesterol embolism. Fundoscopy revealed cholesterol crystals in retinal vascular branches thus delivering important diagnostic information. Atheromatous lesions of the entire aorta and the ilio-femoral arteries were possible sources for embolism. The outcome was favorable. The lesions of the toes regressed and renal failure did not progress to dialysis. The diagnostic steps taken, the clinical picture of cholesterol embolism, the use of imaging and therapeutic options are discussed.
