ABSTRACT
Systemic cholesterol embolism is a rare complication of atherosclerosis, and has various presentations. Arterial catheterisms are a common cause. However, the association with an aortic dissection has been exceptionally reported. We report the observation of a 70 year-old man, with coronary artery disease, hypertension, diabetes and dyslipidemia. Six months before hospitalization, a coronary angioplasty was performed due to recurrent angina. The association of purpuric lesions on the feet, with acute renal failure confirmed cholesterol embolism syndrome. Transoesophageal echocardiography showed a dissection of the descending thoracic aorta associated with complex atheroma. The evolution was marked by the pulpar necrosis of a toe and by a worsening of the renal failure, requiring definitive hemodialysis. Further echographic control highlighted the rupture of the intimal veil of the dissection. Cholesterol embolism syndrome may reveal an aortic dissection in patients without thoracic symptoms. In such cases, transoesophageal echocardiography is a useful and non-invasive examination.
