title: [Multiple cholesterol athero-embolisms after resection of an abdominal aortic aneurysm].
abstract: A 72-year-old man underwent resection of an infrarenal aortic aneurysm; during postoperative recovery, multiorgan failure developed secondary to cholesterol emboli in several arteries. The initial sign consisted of patches of livedo in the lower limbs with pedal pulses, hematuria and hyperdynamic shock with high cardiac output and reduced vascular resistance. The clinical picture progressed to multiple organ failure with non-cardiogenic pulmonary edema, oliguric kidney failure, coagulopathy, necrotizing pancreatitis and colic ischemia. The patient died 15 days after surgery. The formation of multiple cholesterol emboli is a rare complication after aortic surgery, vascular catheterization or anticoagulant treatment. It is caused by cholesterol crystals measuring 100 to 200 mu that embolize and block small arteries. Diagnosis is difficult because the organs involved can be many and various. No specific treatment is available and the rates of morbidity and mortality are high.
