ABSTRACT

The cholesterol crystal embolism is a systemic disease characterized by the occlusion of small arteries due these crystals, which come from the atheroma plaques of the walls of major arteries. This clinical case corresponds to a 77-year-old male patient with risk factors for cardiovascular disease who entered at the emergency service due dyspnea and orthopnea. In the Coronary Unit, a clinical status of acute heart failure was diagnosed, receiving medical treatment with good response. It was decided to perform a coronary angiography which showed a severe coronary atherosclerosis with 3-vessel compromised and endovascular treatment was performed with stent placement. After 20 days, the patient evolved with melenic depositions oligoanuria and progressive intermittent claudication in both lower limbs. Obstruction of arterial flow was observed in both pedia arteries by doppler ultrasound. Skin biopsies of lower limbs revealed vascular signs of deposits of cholesterol crystals. It was recognized as a cholesterol crystal disease secondary to previous medical catheterization procedures, causing ischemia and persistent alterations in the digestive and renal systems as well as in the skin of the lower limbs. This is an important affection because it is a serious process that demands a high level of clinical suspicion, the definitive diagnosis is established through the biopsy of the cutaneous lesions and the prognosis depends on the extension of the disease. Nowadays, there is no specific medical treatment of this disease.
