Abstract
Cholesterol crystal embolism (CCE) is caused by the shedding of cholesterol crystals into the bloodstream, and it has been recently recognized as a serious complication after vascular procedures. Our case of CCE, which was diagnosed by skin and renal biopsies, occurred in a patient with hypertension and diabetes mellitus, 3 months after coronary angiography, with the development of renal failure and blue toes. After low-density lipoprotein apheresis (LDL-A), the skin lesions, including livedo reticularis and pain from the acrocyanotic toes, dramatically improved, with partial recovery of renal function. Following the administration of low-dose corticosteroid and candesartan--an angiotensin II type 1 receptor antagonist (ARB)--the eosinophilia disappeared and renal function improved gradually with a decrease in urinary protein excretion. Therefore, a combination therapy of LDL-A, low-dose corticosteroid, and an ARB is a possible treatment for CCE, although the possibility of spontaneous recovery of renal function cannot be eliminated for this patient.

Abstract
Cholesterol crystal embolization syndrome is a multiorgan disease that frequently occurs as a complication of invasive cardiovascular procedures and of thrombolytic or anticoagulant therapy. The symptoms are due to the displacement of atheromatous material dislodged from unstable or injured, by mechanical manipulation, plaque to arteriolar vessels. The real incidence of cholesterol embolization is not known. Often the diagnosis is missed because of the time between intervention and clinical findings and because the organs involved can be many and various. The most common clinical manifestations are acute renal failure and hypereosinophilia. The prognosis is poor and the mortality high because of the progression of renal failure. In this case report we present the clinical history of a 62-year-old male patient with a history of cigarette smoking and hypertension who was submitted to emergency surgery following the acute dissection of a type A aortic aneurysm. About 2 weeks after surgical intervention the patient developed a multiorgan disorder (gastroenteric, neuromuscular and renal involvement) associated with hypereosinophilia and with increased levels of the markers of inflammation. The symptoms were transient and probably due to embolization of cholesterol crystals; no specific therapy was administered. On the other hand, no therapeutic regimen has been codified to date. The best clinical approach is prophylactic, that means identifying those patients who are at high risk for an invasive vascular procedure.

Abstract
FROM AN EPIDEMIOLOGICAL POINT OF VIEW: With the aging of the population and increased indications for angioplasty or anticoagulant therapy, the incidence of cholesterol crystal embolism is going to increase. FROM A CLINICAL POINT OF VIEW: A systemic disease related to multiorgan distal ischemia, cholesterol crystal embolism has multiple facets. Rapidly progressive renal failure, malignant hypertension in the elderly, mesenteric ischemia, acute pulmonary edema, cutaneous ischemia or encephalopathy symptomatology may reveal cholesterol crystal embolism. THE IMPORTANCE OF DIAGNOSIS: The occurrence of such symptoms in poly-vascular patients, notably following exposure to inductive factors such as arterial catheterism, anticoagulant therapy or cardiac or vascular surgery is highly suggestive of the diagnosis. The lack of its knowledge can lead to inappropriate anticoagulant therapy and useless arteriography, which may even prolong or worsen cholesterol crystal embolism.

Abstract
Cholesterol crystal embolisation (CCE) is a rare but serious complication of invasive arterial procedures associated with a high mortality, and is a condition that medical staff undertaking invasive vascular procedures should be aware of. It is manifest as a multisystem disorder commonly involving the kidneys and peripheries, but rarely affecting the lungs. A case of fatal CCE with pulmonary involvement is reported, and similar published case reports are reviewed. The pathogenesis of lung involvement in CCE is unclear, but the combination is reported to be invariably fatal.

Abstract
We report on a 68-year-old patient who was admitted with hemiparesis and disorientation. Computed tomography showed several old, mostly lacunar infarcts. One week after admission, the patient became comatose. A repeat computed tomography revealed several new hypodense lesions in both hemispheres compatible with acute cerebral infarctions. Autopsy confirmed the diagnosis of numerous acute encephalomalacias of the same age which were found in different territories of the anterior cerebral circulation. Histologic examination showed the extraordinary result of multiple cholesterol emboli with a maximum in the peripheral leptomeningeal vessels. The source of the emboli was severe atherosclerosis with an ulcerated and thrombotic surface of the aorta and both carotid arteries. This case is remarkable because of its severe and synchronous emboli of cholesterol in several different cerebral territories. One has to suspect a so far unknown physical or metabolic factor responsible for the shower of emboli.

Abstract
A 53 year old male was admitted with the diagnosis of brain stem infarction. Severe stenosis of the bilateral internal carotid arteries was revealed by cerebral angiography. During the angiography, he complained of acute abdominal pain and was referred to abdominal surgical department. He was diagnosed as thrombo-embolism of the superior mesenteric artery and treated conservatively. The symptoms improved, but renal function became worse and the toe was found to be blue. Cholesterol embolism was suspected by nephrologists and thrombolytic therapy was discontinued. Steroid was administrated and LDL-apheresis was performed. The renal function was aggravating and hemodialysis was required. Emergency neurosurgical operations are sometimes performed immediately after cerebral angiography and the neuroanesthesiologists should be aware of the pathology of cholesterol embolism in perioperative management.

Abstract
BACKGROUND Cholesterol embolization syndrome (CES) is an increasingly recognized cause of acute renal insufficiency, which must be differentiated from other forms of systemic vasculitis by histologic examination of biopsies from involved organs. This report describes the optimal methods for detection and biopsy of areas of skin involved with livedo reticularis to confirm the diagnosis of CES. METHODS This report describes 8 patients with unexplained acute renal insufficiency in whom the diagnosis of CES was suspected based on their clinical history. RESULTS A detailed skin examination performed in both supine and upright postures demonstrated the presence of previously unrecognized livedo reticularis, which was more evident during upright posture in all subjects. In 2 subjects, questionable areas of livedo reticularis noted in supine posture became readily demonstrable during upright posture. Livedo reticularis was apparent only during upright posture in 2 subjects. Biopsies of areas of skin involved with livedo reticularis demonstrated cholesterol emboli in 6 of 8 patients and were normal in the remaining 2 patients. One patient progressed to end-stage renal disease and one was lost to follow-up. In the remaining 6 patients, renal insufficiency initially progressed but did not require dialytic therapy. Renal function returned to baseline levels and livedo reticularis resolved without recurrence in these patients. No subjects developed clinical or laboratory evidence of systemic vasculitis. CONCLUSIONS Livedo reticularis is a common but often unrecognized finding in CES that may not be evident during routine examination performed in the supine posture. Deep cutaneous biopsy of areas of livedo reticularis can be safely used to confirm the presence of cholesterol emboli, thus avoiding the increased morbidity of biopsy of either pregangrenous skin lesions or visceral organs. Many patients with CES regain renal function during long-term follow-up.

Abstract
Cholesterol crystal embolization usually produces characteristic skin lesions. We report a case responsible for myositis of the calf without suggestive skin lesions. The outcome in this 58-year-old patient was spontaneously favorable. Cholesterol crystal embolization can produce a range of clinical symptoms, with the skin, kidneys, and eyes being the most common targets. Generalized forms can result in systemic disease. The diagnosis rests on histological findings, and the treatment is symptomatic. Anticoagulants have been shown to worsen the manifestations, whereas antiplatelet therapy may be useful.

Abstract
Cholesterol Crystals Embolization is not a very frequent entity that happens in people with atheromatous disease of spontaneous for or after the realization of vascular manipulation (angiographic, angioplasty procedures, cardiovascular surgery) or more rarely with the treatment with oral anticoagulants and after thrombolytic therapy. The clinical presentation is according to the arterial affected territory and so from diagnosed cases in autopsy reports to florid clinic forms exist. The more frequent are the cutaneous manifestations with apparition of livedo reticularis and purple toes that could go accompanied of necrosis of lower limbs, consecutive from the renal manifestations and the gastrointestinal tract one. The diagnosis is based on the biopsy of organ affected lesions to level of arterioles, that revealed characteristic cholesterol clefts, above all the cutaneous biopsy, muscular and in any case renal. As for the treatment is symptomatic with analgesics, antiplatelet agents, anti-inflammatory, etc ... but it doesn't after the presage and the evolution of the illness. A clear contraindication exists to the use of oral anticoagulants and heparin.

Abstract
Circulating concentrations of C-reactive protein (CRP), the classical acute phase protein and sensitive systemic marker of inflammation, significantly predict atherothrombotic events and outcome after acute myocardial infarction, demonstrating the key role of inflammation in atherosclerosis and its complications. The binding specificity of CRP for low density lipoproteins, for modified low density lipoproteins, and for damaged and dead cells, coupled with the capacity of bound CRP to activate complement, and with the presence of CRP in atheroma and acute myocardial infarction lesions, all suggest a possible pathogenetic role of CRP. Development of drugs to block binding of CRP to its various ligands in vivo will enable this hypothesis to be tested.

Abstract
BACKGROUND The cholesterol embolism syndrome is a multisystemic disease resulting from cholesterol crystal embolization to many organs including skin, kidney and CNS. Vascular procedures and anticoagulation have been identified as triggering factors. PATIENTS AND METHODS Sixteen patients were prospectively reviewed diagnosed of cholesterol embolism syndrome from 1991 to 1998. RESULTS The mean age was 68 years and all had at least two risk factors for atherosclerosis (hypertension, smoking, diabetes mellitus, hyperlipemia) as well as pre-existing symptomatic atherosclerotic disease. At least one precipitating factor was identified in 14 patients (heparin in 7, coumarins in 4 and vascular procedure in 7). In six patients two or more triggering factors coexisted. Clinically, 12 patients had livedo reticularis, 10 purpuric lesions, 12 purple toes and 4 painful ulcerations. As a result of progressive gangrene 4 patients required amputation of a portion of the lower extremity. The skin biopsy was diagnostic of cholesterol embolism syndrome in 10 cases and was highly suggestive in the remaining cases. Eleven patients developed renal failure but only five required subsequent dialysis. A cerebrovascular accident was reported in two patients and gastrointestinal bleeding occurred in another three patients. Four patients died but only two as a direct result of the disease. CONCLUSIONS The diagnosis of cholesterol embolisms should be considered among elderly patients, with underlying atherosclerotic disease, who develop typical cutaneous manifestations, hypertension, and renal failure in association with precipitating factors. Given the serious implications of this syndrome, a heightened awareness and preventive measures in the population at risk are essential.

Abstract
Cholesterol crystal embolism, sometimes separately designated atheroembolism, is an increasing and still underdiagnosed cause of renal dysfunction antemortem in elderly patients. Renal cholesterol crystal embolization, also known as atheroembolic renal disease, is caused by showers of cholesterol crystals from an atherosclerotic aorta that occlude small renal arteries. Although cholesterol crystal embolization can occur spontaneously, it is increasingly recognized as an iatrogenic complication from an invasive vascular procedure, such as manipulation of the aorta during angiography or vascular surgery, and after anticoagulant and fibrinolytic therapy. Cholesterol crystal embolism may give rise to different degrees of renal impairment. Some patients show only a moderate loss of renal function; in others, severe renal failure requiring dialysis ensues. An acute scenario with abrupt and sudden onset of renal failure may be observed. More frequently, a progressive loss of renal function occurs over weeks. A third clinical form of renal atheroemboli has been described, presenting as chronic, stable, and asymptomatic renal insufficiency. The renal outcome may be variable; some patients deteriorate or remain on dialysis, some improve, and some remain with chronic renal impairment. In addition to the kidneys, atheroembolization may involve the skin, gastrointestinal system, and central nervous system. Renal atheroembolic disease is a difficult and controversial diagnosis for the protean extrarenal manifestations of the disease. In the past, the diagnosis was often made postmortem. However, in the last decade, awareness of atheroembolic renal disease has improved, enabling us to make a correct premortem diagnosis in a number of patients. Correct diagnosis requires the clinician to be alert to the possibility. The typical patient is a white man aged older than 60 years with a baseline history of hypertension, smoking, and arterial disease. The presence of a classic triad characterized by a precipitating event, acute or subacute renal failure, and peripheral cholesterol crystal embolization strongly suggests the diagnosis. The confirmatory diagnosis can be made by means of biopsy of the target organs, including kidneys, skin, and the gastrointestinal system. Thus, Cinderella and her shoe now can be well matched during life. Patients with renal atheroemboli have a dismal outlook. A specific treatment is lacking. However, it is an important diagnosis to make because it may save the patient from inappropriate treatment. Finally, recent data suggest that an aggressive therapeutic approach with patient-tailored supportive measures may be associated with a favorable clinical outcome.

Acute renal failure due to diffuse renal infiltration is rarely the presenting manifestation of non-Hodgkin's lymphoma. We report a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a Burkitt's lymphoma. The presence of bilateral renal enlargement, an elevated serum lactate dehydrogenase (LDH), and lymphopenia should suggest the diagnosis, which can be confirmed by renal biopsy.

Abstract
Cholesterol emboli (CE) to the brain are an important but often unrecognized cause of stroke. The authors reviewed 29 cases of brain CE identified on autopsy. Most patients were elderly (mean age, 74 years) and presented with encephalopathy and acute renal failure. Ten patients developed symptoms spontaneously, 19 after a procedure involving manipulation of the aorta. Brain imaging revealed multiple, small ischemic lesions and border zone infarcts in 11 of 17 patients. Pathology in most patients demonstrated multiple CE mixed with emboli of other types.

Abstract
The syndrome of cholesterol embolism is a multiorgan disorder caused by peripheral embolization of cholesterol crystals from an ulcerated aorta plaque. The kidney is the organ most often affected (approx 50%). Prognosis is poor, with a mortality of about 70%. We describe two of four cases of cholesterol embolism diagnosed during the autumn of 1997. All were elderly men with advanced generalized atherosclerosis. Positive diagnosis upon renal biopsy required demonstrating cholesterol crystals in renal interlobar and arcuate arteries. Workups for progressive renal failure were performed due to suspected vasculitis in three cases and radiologically induced renal damage subsequent to coronary angiography in another. None of the patients showed renal vasculitis upon biopsy, but one who was ANCA positive developed vasculitis after a few months. Three patients died within a couple of months of onset. The patient with renal vasculitis was treated with cyclophosphamide and steroids, and survives one and a half years after onset. It is vital to consider the diagnosis cholesterol embolism whenever an elderly patient with pronounced atherosclerosis develops progressive renal failure and multi-organ failure. Angiography, aorto-iliaco-femoral surgery and thrombolytic therapy increase the risk of cholesterol embolism in this group. There is no effective therapy. The key is prophylaxis, which means identifying patients at risk prior to invasive vascular procedures.

Abstract
Cholesterol embolism is a rare but potentially serious complication of cardiac catheterization. We report the case of a patient who presented a cholesterol embolism in the lower extremities after percutaneous angioplasty and the elective implantation of a stent. Clinical evolution was favourable. The appearance of cholesterol embolism could have been precipitated, in this case, by anticoagulation treatment with heparin and intense antiaggregation.

Abstract
Cholesterol crystal emboli are a serious complication of atheroma. The incidence of this syndrome appears to be much more common in patients in their sixties with severe atheromatous disease of the aorta (20 to 30% vs less than 5%). 80% of crystal embolism result from medical interventions (aortic or cardiac surgery, arterial invasive procedure of aorta, thrombolytic therapy). Embolisation of cholesterol crystals can give rise to a confusing clinical pictures, depending of the site (organ) of the embolisation. It also can simulate a systemic disease. The diagnosis must be discuss in all atheromatous patients. The prognosis is poor because of the patient's clinical context and because there is no specific treatment. The best treatment is prevention by improving the recognition of the high risk patients and avoiding in those cases the predisposing factors.

Abstract
The multiple cholesterol emboli syndrome (MCES) is a rare, multi-organ disease than can occur spontaneously or after arterial or cardiac catheterization, arteriography, angioplasty, cardiovascular surgery, oral or intravenous anticoagulation, systemic fibrinolysis and cardiorespiratory resuscitation, predominantly in male subjects with disseminated atherosclerosis over the age of 60 years. Clinical signs of MCES vary considerably depending on the organs involved, but the signs most frequently encountered are renal failure, skin lesions (livedo reticularis, purple toc, ulcers, etc) and transient eosinophilia. Optimal treatment of this syndrome is controversial and is often symptomatic. However, the most effective measure remains prevention based on identification of high-risk patients, treatment with platelet antiaggregants and careful handling of catheters. This syndrome has a serious prognosis in the majority of cases. In this article, the authors describe a case of MCES. After thoracic aortography, this 73-years-old patient presented typical clinical sign of MCES (angina, cerebrovascular accident, bilateral blindness, transient renal failure and splenic infarction). The clinical course was favourable in response to heparin therapy and splenectomy and caudal pancreatectomy. Histology confirmed the presence of cholesterol emboli in the lumen of splenic arterioles. Except in the case of severe bleeding diathesis, the authors recommend early heparin therapy for MCES caused by catheterization, angioplasty or cardiovascular surgery. However, complementary studies must be performed to more clearly define the effects of heparin on MCES.

Abstract
BACKGROUND Atheroembolization is a recognized complication of cardiac surgical procedures, and has been implicated in postoperative stroke, renal failure, multiorgan failure, and death. Preoperative identification of patients at risk for developing atheroemboli is essential. The aim of this study was to determine preoperative risk factors for atheroemboli and to assess the postoperative course of the patients who developed atheroembolic syndrome. METHODS A retrospective record review was conducted. From 1/1990 to 12/1994 5486 patients underwent coronary artery bypass grafting (CABG), valve operations, or other cardiac surgical procedures at Massachusetts General Hospital. Of this population, 107 patients (1.9%) developed atheroembolic syndrome. RESULTS Patients who develop atheroemboli were older, with an increased incidence (p < 0.01) of hypertension, cerebrovascular disease, and aortoiliac disease. Many had a complicated course after catheterization, with renal insufficiency (35%) and evidence of peripheral emboli (12%). Average Intensive Care Unit stay, hospital stay, and hospital cost of these patients were respectively 16.8 days, 48.4 days, and $88,000, compared to 1.5 days, 9.6 days and $23,000 for a concurrent population undergoing CABG surgery. Of these 107 patients only 2 were discharged home, the others either died (48 patients, or 25% of all cardiac surgical deaths during this period), or went to rehabilitation or chronic hospital facilities. Twenty-seven autopsies were performed and invariably showed a diffusely diseased aorta, with calcification, mural thrombus, and ulceration. CONCLUSIONS Atheroembolization during cardiac surgical procedures has profound medical and economic consequences. Because of the diffuse nature of aortic disease, measures approaching the disease as a local process are likely to be unsuccessful. Appropriate evaluation would ideally identify patients with extensive aortic atheromatous disease, prior to rather than during surgery.

Abstract
The signs and symptoms of vasculitis are not specific, and tests for confirming the diagnosis can be misleading. Thus, when considering a diagnosis of vasculitis, physicians need to keep an open mind. With a case vignette, the author illustrates some of the difficulties in diagnosing "vasculitis."
