The Target Vessel SYNTAX Score: A Novel Pre-Procedural Predictor for Contrast-Induced Acute Kidney Injury After Rotational Atherectomy. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 47:18-24. [PMID: 36057490 DOI: 10.1016/j.carrev.2022.08.035] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 08/06/2022] [Accepted: 08/24/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Rotational atherectomy (RA) is a complex procedure often associated with high contrast load. Known risk scores do not predict contrast-induced acute kidney injury (CI-AKI) before RA. We aim to investigate pre-procedural predictors of CI-AKI after RA, and the role of the target vessel SYNTAX score (tvSS). METHODS Among 295 patients who underwent RA between 01.2010 and 02.2019 at a single center, 49 developed CI-AKI. Those who were on chronic hemodialysis or with no available 48-h' kidney function tests were excluded. Predictors of CI-AKI were assessed in the whole cohort and those with no basal renal impairment. RESULTS The rate of CI-AKI was 16.6 %. The tvSS was 18 [14-23] vs. 12 [9-18] in patients with vs. without CI-AKI (p < 0.001). The tvSS cut-off value of 15 provided 75 % sensitivity and 60 % specificity for predicting CI-AKI. Consequently, a tvSS ≥15 emerged as an independent pre-procedural predictor for CI-AKI (adjusted OR: 4.94, 95 % CI: 2.38-10.20, p < 0.001), along with left ventricular ejection fraction (LVEF) ≤35 % (p = 0.016) and glomerular filtration rate (GFR) <45 ml/min (p = 0.004). TvSS was the only independent pre-procedural predictor for CI-AKI in patients with GFR ≥60 ml/min (p < 0.001). The contrast volume/GFR ratio and peri-procedural myocardial infarction (MI) were independent procedural predictors for CI-AKI in the whole cohort and in patients with basal GFR ≥60 ml/min. CONCLUSION CI-AKI after RA is frequent. The tvSS is an efficient pre-procedural predictor for CI-AKI after RA, along with LVEF ≤35 % and GFR <45 ml/min. Contrast volume/GFR ratio and peri-procedural MI emerged as procedural predictors for CI-AKI.

Abstract
Cholesterol crystal embolization (CCE) is a rare, mainly iatrogenic condition. The proportion of CCE after cardiovascular procedures has not been fully elucidated. The purpose of this study was to determine the proportion of CCE diagnosed after cardiovascular procedures and to identify risk factors for CCE occurrence. Data on patients aged older than 40 years who underwent cardiovascular procedures between July 2010 and March 2017 were extracted from the Japanese Diagnosis Procedure Combination database. Inpatients diagnosed with CCE within 1 year after procedures in the same hospital were identified. Logistic regression analysis was performed to identify factors associated with the occurrence of CCE. There were 962 patients with CCE in 2,190,300 patients who underwent cardiovascular procedures. The overall proportion of CCE after cardiovascular procedures was 4.4 per 10,000 patients (95% confidence interval 4.1-4.7). The overall in-hospital mortality among patients with CCE was 11% (107/962). Older age, male sex, smoking, heart failure, peripheral vascular disease, cerebrovascular disease, renal insufficiency, diabetes mellitus, hypertension, and aortic aneurism and dissection were significantly associated with the higher occurrence of CCE. Compared with cardioangiography, several procedures were significantly associated with higher occurrence of CCE, including intra-aortic balloon pumping, percutaneous transluminal angioplasty of the renal artery, and transcatheter aortic valve implantation or balloon aortic valvuloplasty. CCE is rare but remains a severe complication of cardiovascular procedures. Atherosclerotic risk factors and certain cardiovascular procedures were associated with CCE.

Abstract
Cholesterol-embolization syndrome (CES) is a multisystemic disease with various clinical manifestations. CES is caused by embolization of cholesterol crystals (CCs) from atherosclerotic plaques located in the major arteries, and is induced mostly iatrogenically by interventional and surgical procedures; however, it may also occur spontaneously. Embolized CCs lead to both ischemic and inflammatory damage to the target organ. Therefore, anti-inflammatory agents, such as corticosteroids and cyclophosphamide, have been investigated as treatment for CES in several studies, with conflicting results. Recent research has revealed that CES is actually a kind of autoinflammatory disease in which inflammasome pathways, such as NLRP3 and IL1, are induced by CCs. These recent findings may have clinical implications such that colchicine and IL1 inhibitors, namely canakinumab, may be beneficial in the early stages of CES.

Abstract
Peri-operative acute kidney injury is common, accounting for 30-40% of all in-hospital cases of acute kidney injury. It is associated with clinically significant morbidity and mortality even with what was hitherto regarded as relatively trivial increases in serum creatinine, and carries over a 12-fold relative risk of death following major abdominal surgery. Comorbid conditions such as diabetes, hypertension, liver disease and particularly pre-existing chronic kidney disease, as well as the type and urgency of surgery, are major risk factors for the development of postoperative acute kidney injury. As yet, there are no specific treatment options for the injured kidney, although there are several modifiable risk factors of which the anaesthetist should be aware. As well as the avoidance of potential nephrotoxins and appropriate volume balance, optimal anaesthetic management should aim to reduce the risk of postoperative renal complications. This may include careful ventilatory management and blood pressure control, as well as appropriate analgesic strategies. The choice of anaesthetic agent may also influence renal outcomes. Rather than concentrate on the classical management of acute kidney injury, this review focuses on the potential development of acute kidney injury peri-operatively, and the means by which this may be ameliorated.

Abstract
Atheromatous embolization is a multisystem disease complicating advanced atherosclerosis. It occurs most often as a complication of angiography, an endovascular procedure or cardiovascular surgery. Atheromatous embolization can present in a subtle manner where it is often under-recognized, or with catastrophic results including myocardial infarction, strake or acute renal failure. It may mimic other disease processes and often goes underdiagnosed and undertreated. A high clinical suspicion is the key to diagnosis. Atheromatous embolization results in significant morbidity and mortality; therefore, early recognition followed by aggressive management may help to prevent end-organ damage and improve overall clinical outcomes. Management strategies should include risk factor modification, prevention of further insults by discontinuing or avoiding predisposing factors, supportive treatment and interventional or surgical approaches to remove the atheroembolic source. Atheromatous embolization is expected to increase as our population ages and the epidemics of diabetes mellitus and obesity increase.

Abstract
Renal artery stenting remains an important adjuvant treatment for true-resistant hypertension, although recent disappointing randomized trials highlight the importance of careful patient selection. Safe and successful renal interventions begin with critical core knowledge regarding renal artery anatomy and understanding the often hostile nature of the parent vessel (pararenal aorta). Armed with fundamental knowledge about anatomy and renal ostial disease pathology, it becomes easier to understand the advantages of less traumatic access techniques and how low-profile contemporary flexible stents have enhanced outcomes. In addition to suggested techniques based on detailed understanding of the vessel architecture and pathology, we will review the current available US Food and Drug Administration-approved balloon-expandable on-label renal stents and discuss the role of intravascular ultrasound for definition of lesion severity, stent sizing, and stent apposition. The durability of renal stenting will also be discussed, as will the velocity criteria for duplex surveillance. Lastly, the current empirical data related to renal embolic protection is provided, along with insight into technical issues in this domain.

Abstract
Cholesterol embolization syndrome (CES) is a complication sometimes occurring after invasive endovascular procedures. CES is characterized by release of cholesterol crystals and particles from atheromatous plaques, which can occlude distal vessels and induce an inflammatory response, resulting in end-organ damage. We report the case of a 66-year-old man who presented with an acute ST-elevation myocardial infarction. An intra-aortic balloon pump was placed due to hemodynamic instability following percutaneous coronary intervention. Ten weeks after discharge, he presented with signs and symptoms of CES (e.g., livedo reticularis, acrocyanosis, acute renal failure), and a new left ventricular apical thrombus. Withdrawal of anticoagulation is often recommended in the setting of CES, on the presumption that anticoagulants favor plaque hemorrhage and subsequent cholesterol micro-embolization. Because of the potential disastrous consequences of an embolus, the patient was anticoagulated with warfarin concurrently with corticosteroids to suppress the inflammatory response to cholesterol crystals. His renal function continued to improve and was discharged without the need for dialysis. This case illustrates that anticoagulation therapy in CES is feasible and appears to be safe in patients with a coexisting urgent indication for anticoagulation.

Abstract
Atheroembolic renal disease develops when atheromatous aortic plaques rupture, releasing cholesterol crystals into the small renal arteries. Embolisation often affects other organs, such as the skin, gastrointestinal system, and brain. Although the disease can develop spontaneously, it usually develops after vascular surgery, catheterisation, or anticoagulation. The systemic nature of atheroembolism makes diagnosis difficult. The classic triad of a precipitating event, acute or subacute renal failure, and skin lesions, are strongly suggestive of the disorder. Eosinophilia further supports the diagnosis, usually confirmed by biopsy of an affected organ or by the fundoscopic finding of cholesterol crystals in the retinal circulation. Renal and patient prognosis are poor. Treatment is mostly preventive, based on avoidance of further precipitating factors, and symptomatic, aimed to the optimum treatment of hypertension and cardiac and renal failure. Statins, which stabilise atherosclerotic plaques, should be offered to all patients. Steroids might have a role in acute or subacute progressive forms with systemic inflammation.

Abstract
Cholesterol embolization syndrome (CES) induced by thrombolytic therapy is a rare syndrome with a high incidence of morbidity and mortality. The variability in clinical presentations may cause a delay in diagnosis of CES. This article presents a comprehensive review of the English literature from January 1980 to December 2007 identifying all published case reports of CES induced by thrombolytic therapy. Multiple electronic databases were searched and relevant reference lists were hand searched to identify all case reports. Thirty cases of thrombolytic-induced CES were identified. Indications for thrombolysis were acute myocardial infarction (28 patients) and deep venous thrombosis (two patients). Skin and renal involvement were the most common presentations. Skin manifestations included livedo reticularis, rash, and skin mottling. Other clinical symptoms included cyanotic toes, gastrointestinal bleeding, or perforation, myalgias, retinal emboli, and CNS involvement. Morbidity and mortality were high. Outcomes included chronic hemodialysis in eight patients, four patients underwent amputations, seven patients developed or had progression of their chronic kidney disease, and seven deaths occurred.CES presents as multiorgan dysfunction and should be considered in the differential diagnosis of the symptom complex that may develop after thrombolytic therapy. Diagnosis of CES can be difficult as a result of the variable clinical presentations. A thorough clinical history and physical examination are essential first steps in establishing a diagnosis. Confirmatory diagnosis requires biopsy of the target organs. Measures to reduce the likelihood of recurrence should be taken and include avoidance of anticoagulation therapy and vascular procedures. Unfortunately, therapy remains supportive and the outcome is invariably poor.

Abstract
Patients with severe aortic atherosclerosis are at high risk for stroke and other embolic complications. Therapy to prevent emboli from aortic plaque is not yet established. Therefore, patients with atherosclerosis or risk factors for embolic disease should be identified and treated aggressively. Aspirin, smoking cessation, and control of blood pressure and glucose are important. Retrospective data in patients with severe aortic plaque support the use of statins to prevent stroke. Iatrogenic embolization can occur as a result of aortic manipulation during invasive vascular procedures or cardiovascular surgery. The risks and benefits of these procedures must be carefully weighed, and alternate approaches should be considered for patients with severe aortic atherosclerosis. For those who require coronary artery bypass graft (CABG) surgery, off-pump CABG is an option. Prophylactic aortic arch atherectomy should not be routinely performed. Aortic filters or stenting have been introduced but have not yet been fully evaluated. For patients who require angiography and have severe descending aortic, aortic arch, or abdominal aortic plaque, it is possible that a brachial (rather than a femoral) approach may avoid embolic complications.

Abstract
A aterotrombose é uma doença multissistêmica associada a elevada morbidade e mortalidade. A manipulação das artérias com fios-guia ou cateteres pode gerar trauma mecânico, com conseqüente deslocamento de material ateromatoso da parede vascular. Um paciente de 82 anos, no qual uma ponte fêmoro-poplítea distal com veia safena in situ havia sido realizada por nós há 10 anos, apresentou dor, palidez, hipotermia, diminuição da sensibilidade e força do pé direito 6 horas após coronariografia com acesso pela artéria femoral direita (classe 2b de Rutherford). Arteriografia diagnóstica evidenciou perviedade do enxerto, com múltiplas irregularidades em seu terço distal, compatíveis com material ateroembólico, além de pobreza extrema de circulação distal. Optamos pela revascularização do membro inferior direito em caráter de urgência, associando técnicas convencionais a métodos endovasculares. Empregando a técnica de push and park, cruzamos a lesão ateroembólica com fio-guia e tratamos todo o eixo arterial acometido com manobras de angioplastia. O paciente apresentou boa evolução, boa perfusão distal, adequado enchimento capilar, eliminação da dor e melhora acentuada imediata do déficit motor e sensitivo.

Abstract
Cholesterol embolization (CE) is a potentially serious complication associated with invasive arterial maneuvers, in which standard therapy has not been established. We experienced two cases of CE in patients with severe atherosclerosis whose renal function deteriorated within a few months after invasive arterial maneuvers. CE was confirmed either by renal biopsy (case 1) or skin biopsy (case 2). Oral administration of prednisolone at a daily dose of 30 mg (0.4 mg/kg) was effective to improve their renal function. Our observation suggests that corticosteroid therapy may be beneficial in some patients with CE.

Cholesterol crystal embolization (CCE) is a complication of atherosclerosis. A 67-year-old Japanese man underwent coronary artery bypass grafting. After the surgery, he underwent coronary angiography via the right femoral artery. Twelve days later, he suddenly developed acalculous cholecystitis and was treated with antibiotics. Gradual deterioration in renal function, purplish discoloration of the distal portion of his toes, and eosinophilia were noted. We performed a skin biopsy and made a diagnosis of CCE. Cilostazol and intravenous heparin improved the symptoms and decreased the creatinine level. We retrospectively studied the clinical features of 36 cases registered with a diagnosis of CCE in the Japanese literature.

Abstract
BACKGROUND Cholesterol embolization syndrome is a systemic disease caused by distal showering of cholesterol crystals after angiography, major vessel surgery, or thrombolysis. METHODS We prospectively evaluated a total of 1,786 consecutive patients 40 years of age and older, who underwent left-heart catheterization at 11 participating hospitals. The diagnosis of CES was made when patients had peripheral cutaneous involvement (livedo reticularis, blue toe syndrome, and digital gangrene) or renal dysfunction. RESULTS Twenty-five patients (1.4%) were diagnosed as having CES. Twelve patients (48%) had cutaneous signs, and 16 patients (64%) had renal insufficiency. Eosinophil counts were significantly higher in CES patients than in non-CES patients before and after cardiac catheterization. The in-hospital mortality rate was 16.0% (4 patients), which was significantly higher than that without CES (0.5%, p < 0.01). All four patients with CES who died after cardiac catheterization had progressive renal dysfunction. The incidence of CES increased in patients with atherosclerotic disease, hypertension, a history of smoking, and the elevation of baseline plasma C-reactive protein (CRP) by univariate analysis. The femoral approach did not increase the incidence, suggesting a possibility that the ascending aorta may be a potential embolic source. As an independent predictor of CES, multivariate regression analysis identified only the elevation of pre-procedural CRP levels (odds ratio 4.6, P = 0.01). CONCLUSIONS Cholesterol embolization syndrome is a relatively rare but serious complication after cardiac catheterization. Elevated plasma levels of pre-procedural CRP are associated with subsequent CES in patients who undergo vascular procedures.

Abstract
BACKGROUND Atheroembolism is a recognized complication of cardiac surgery, but its incidence and various outcomes have not been completely described. A retrospective study was undertaken to better characterize the syndrome. METHODS Records of 49,377 autopsies and surgical specimens from the Johns Hopkins Hospital between 1973 and 1995 were reviewed. Three hundred twenty-seven patients (0.7%) had an identifiable atheroembolism on histologic examination. Of these patients, 29 (0.2%) had undergone a cardiac surgical procedure within 30 days of autopsy or surgical resection. Patient charts and pathology specimens were reviewed for operative findings, postoperative outcomes, and histology. RESULTS Six of the 29 patients (21%) had atheroembolism to the heart, 7 patients (24%) had embolism to the central nervous system, 19 patients (66%) had embolism to the gastrointestinal tract, 14 patients (48%) had embolism to one or both kidneys, and 5 patients (17%) had embolism to a lower extremity. Sixteen patients (55%) had atheroembolism in two or more areas. In 6 patients (21%), death was directly attributable to atheroembolism, including intraoperative cardiac failure from coronary embolism (n = 3), massive stroke (n = 2), and extensive gastrointestinal embolization (n = 1). CONCLUSIONS Atheroembolism in cardiac surgery has a broad spectrum of clinical presentations, including devastating injuries and death. Although the true incidence is probably underestimated in this retrospective study, the high attendant mortality and morbidity of atheroembolism have been documented. Improvements in outcome are likely to be associated with preoperative identification of patients at high risk, modifications of perfusion technique, and interventions to minimize secondary thrombosis and progressive organ ischemia.

Abstract
Cholesterol embolization syndrome (CES) may not only be due to direct dislodgement of cholesterol crystals from atherosclerotic plaques on the walls of arteries by surgery, angiogram or trauma, but may occur after anticoagulant and thrombolytic therapy. The latter two therapies both weaken the fibrin clot that stabilizes the atheromas in place; however, these two therapies commonly have different onsets of CES after their institution. We present three patients with different risk factors for CES who all presented with the pathognomonic triad of leg and/or foot pain, livedo reticularis and good peripheral pulses. In all three patients cholesterol emboli were demonstrated in cutaneous biopsy sections. In two patients there was associated renal involvement, which was fatal in one case. These cases illustrate that cutaneous biopsy may be diagnostic in patients with livedo reticularis, which progresses to necrosis and gangrene. In addition, they illustrate the problems and contradictions involved in treating patients with CES.

Abstract
Cerebral embolization has been documented as one of the complications of diagnostic heart catheterization by transcranial Doppler (TCD). This study aimed to evaluate our hypothesis that the nature of embolic signals involved in different stages of catheter manipulation may be distinct. TCD-detected cerebral emboli occurring at different phases of cardiac catheterization were registered and differentiated by comparing their acoustic signatures with the Doppler signals generated from clinically frequently encountered embolic materials in an in vitro middle cerebral artery model. We found that there was a significant difference in embolic signal intensity and duration between different phases of cardiac catheterization. Our data suggest that different types of emboli may be involved in different phases of the catheterization. Cathet Cardiovasc Intervent 2001;53:323-330.

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.

Abstract
Embolic events during cardiac catheterization have been attributed to atherosclerotic aortic debris dislodged by catheter manipulation. We evaluated the frequency and the histologic morphology of atherothrombotic material retrieved during placement of coronary catheters in patients undergoing diagnostic or interventional cardiac procedures. Over a 4-year period, macroscopically visible aortic debris from coronary catheters, if present after advancement to the ascending aorta, was obtained for histologic examination. In 41 of 7,621 patients (0.54%), visible atherothrombotic material was present in the backflow of catheters. Debris occurred most frequently with 8 Fr guiding catheters (98%). Histologic examination showed foam cells, cholesterol crystals, and amorphic lipoid substance as markers of atheromatous material from atherosclerotic plaques in 38/41 patients (93%) with former plaque hemorrhage in 55% of them. In three patients, fresh thrombus material was observed (7%). None of these patients showed in-hospital ischemic complications. Although visible atheromatous material is a rare phenomenon in cardiac catheterization, an increased risk of scraping debris is associated with large-lumen guiding catheters. In order to avoid vascular embolization, the use of smaller guiding catheters and sufficient free backflow of catheters after advancement are recommended.

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
BACKGROUND Cholesterol crystal embolization (CCE) has been documented to affect nearly every organ system. However, CCE involving the lung is distinctly uncommon and has been documented only in the setting of an aortocaval fistula. DESIGN A case at the Massachusetts General Hospital and a MEDLINE search of English-language medical articles published between 1966 and 1997 provide the basis for this report. RESULTS The precipitants of CCE include invasive vascular procedures, anticoagulant therapy, and thrombolysis. The most common symptoms include claudication of the calf, gastrointestinal bleeding, and weight loss. The most common signs include livedo reticularis, gangrene, and ulcers. Azotemia, proteinuria, normocytic anemia, and eosinophilia often are found. Herein is described the first pathologically confirmed case of CCE to the lung in the absence of an arteriovenous fistula. CONCLUSION Pulmonary hemorrhage should now be included in the diverse list of presenting signs of CCE. Moreover, CCE should be considered in the differential diagnosis of pulmonary-renal syndromes.

Abstract
Cholesterol emboli syndrome is a multisystem disorder that can be precipitated by angiographic procedures. We report 5 cases in which the presentation was renal failure. All patients had undergone angiography, but the temporal relation of the procedure to the clinical presentation was highly variable, the interval ranging from one day to four months. With the increase in diagnostic and therapeutic uses of angiography, the cholesterol emboli syndrome is likely to become more frequent and needs to be recognized.

Abstract
Atheroembolic renal failure (AERF) is often seen after vascular procedures in elderly atherosclerotic patients. To estimate the incidence of AERF after coronary angiography, all patients undergoing coronary angiography at the V.A. Medical Center, Dayton, were prospectively evaluated for AERF. Since, unlike contrast nephropathy, AERF develops about a week after the vascular procedure and persists or progresses over weeks and months, serum creatinine was measured just prior to and 3 weeks after coronary angiography. Peripheral signs of cholesterol emboli were also looked for at follow-up visits. Two hundred sixty-seven patients underwent coronary angiography over a fifteen-month period. Most of the patients were sixty years old or older. Mean serum creatinine in these patients prior to coronary angiography was 1.2 mg/dL. Mean serum creatinine after coronary angiography was unchanged (1.2 mg/dL). Only 7 patients had serum creatinine > 2 mg/dL prior to coronary angiography. Two patients died within a week of coronary angiography and 2 did not return for follow-up. Of the remaining 263 patients, 5 had a serum creatinine increase by 0.5 mg/dL or more at three weeks after coronary angiography. Three of 5 had a serum creatinine increase by 1.0 mg/dL or more. Two of these 3 patients eventually died of renal failure. None of these 5 patients had peripheral signs of cholesterol emboli. In selected patients, the incidence of AERF after coronary angiography appears to be very low (< 2%).

Abstract
Cholesterol embolization (CE), usually occurring in males in their sixth or seventh decade of life, can affect multiple organ systems, including the kidney. Interventive diagnostic procedures and aortic surgery greatly increase the risk of CE. Rapid or insidious progression of renal failure in association with surgical or diagnostic radiologic procedures should suggest this diagnosis. Progressive renal insufficiency in older patients with generalized arterial disease should suggest ischemic nephropathy secondary to bilateral renal artery stenosis, renal CE, or both. Recent worsening of hypertension is characteristic of either diagnosis. A number of clinical conditions can simulate renal CE, and final differentiation may be possible only by renal biopsy. Aggressive, supportive management of renal CE is warranted because renal function may stabilize and, in a limited number of cases, may even improve.

Abstract
Atheroembolic disease is an uncommon condition with many interesting manifestations and has been reported following various procedures. Its occurrence following thrombolytic therapy is extremely rare, with only a few case reports in the literature. However, with a widespread application of thrombolysis in patients with acute myocardial infarction, its incidence is likely to increase and therefore this entity needs to be recognized. Early recognition of the illness may help avoid further expensive and unnecessary investigations. We report two cases of atheroembolic disease following the administration of human recombinant tissue plasminogen activator (TPA).

Abstract
The aim of this study was to evaluate the risk of performing cardiac catheterization or intraaortic balloon pump placement in patients with transesophageal echocardiographically detected atherosclerotic aortic debris. Cardiac catheterization was performed in 70 patients with atherosclerotic aortic debris (in 11 via the brachial approach and in 59 via the femoral approach) and in 71 control patients. An embolic event occurred in 10 (17%) of 59 patients with atherosclerotic aortic debris after femoral catheterization compared to 2 (3%) of 71 control patients without atherosclerotic aortic debris (p = 0.01). None of the 11 patients with atherosclerotic aortic debris who underwent brachial catheterization had an embolic event. An intraaortic balloon pump was placed in 10 patients with atherosclerotic aortic debris and in 12 control patients. An embolic event related to placement of the intraaortic balloon pump occurred in 5 (50%) of 10 patients with atherosclerotic aortic debris; no control patient had an embolic event (p = 0.02). Patients with mobile atherosclerotic aortic debris were at the highest risk for catheter-related embolism. The strongest clinical predictors of atherosclerotic aortic debris were advanced age and peripheral vascular disease. Transesophageal echocardiographic recognition of atherosclerotic aortic debris identifies patients at high risk of stroke or peripheral embolism after cardiac catheterization or intraaortic balloon pump placement. If the aortic debris is mobile, the risk is particularly high. When atherosclerotic aortic debris is detected, especially if the debris is mobile, substituting brachial for femoral catheterization and avoiding placement of an intraaortic balloon pump may reduce the risk of embolism.

Abstract
BACKGROUND AND OBJECTIVES Atheroembolism, caused by peripheral embolization of small cholesterol crystals that fracture off of ruptured atherosclerotic plaques in the major vessels, leads to multifocal ischemic lesions and progressive tissue loss. The end result is often ischemic injury in the skin, kidney, brain, myocardium, and intestine, but any organ distal to the culprit lesion may be affected. The precise incidence of this serious clinical syndrome has been difficult to ascertain from the available literature, but it appears to be much more common than has been assumed. The objective of the present study is to clarify the incidence of atheroembolism among inpatients in an acute hospital setting. PATIENTS AND METHODS We surveyed inpatient nephrology consultations during a 7-month period from January through July 1994. From a pool of 402 consultation charts, 99 were identified with two or more substantive risk factors for atheroembolism. The records of 85 of these patients were available for careful review. More than 300 additional patients were found to have ICD-9 discharge codes for other vascular conditions, but we were unable to confirm that any of these were in fact cases of atheroembolism, since there is no specific ICD-9 discharge code for this entity. In the 85 cases reviewed, a diagnosis of atheroembolism was made only if the patient had identifiable substantive risk factors, suggestive physical findings, and supporting laboratory results. RESULTS Eleven of the 85 surveyed records documented strong evidence supporting a "probable" diagnosis of atheroembolism. Tissue was examined in 4 of these 11, resulting in definitive histologic confirmation in 3. Another 5 of the 85 surveyed records were "suggestive" of atheroembolism. Altogether, atheroembolism was a likely diagnosis in a total of 16 cases during this 7-month period, or 1 case in every 2 weeks. These cases comprised 19% of nephrology consultations in which 2 or more risk factors were present, or 4% or all nephrology consultations. The patients' records confirmed the serious implications of clinically detectable atheroembolism. Several patients underwent lower extremity amputation, nearly half required acute or chronic dialysis, and more than half died within several months of diagnosis CONCLUSIONS The present study suggests that at least 4% of all inpatient nephrology consultations, representing approximately 5% to 10% of the acute renal failure encountered, involve clinically significant atheroembolism. Patients with atheroembolism appear at a rate of at least 1 case every 2 weeks. They often have identifiable substantive risk factors at initial consultation, and probably represent only the most severe cases of atheroembolism. In view of the serious implications of this basically untreatable syndrome, heightened awareness and preventive maneuvers in the population at risk are essential.

Abstract
Cholesterol embolisation has been reported in 27 patients receiving thrombolytic therapy for acute myocardial infarction (MI). Since cholesterol embolisation is so difficult to diagnose ante mortem, it is possible that these cases represent the 'tip of the iceberg', and that cholesterol embolisation in this setting is far more common than usually suspected. However, the risks of cholesterol embolisation are far outweighed by the survival benefits of thrombolytic therapy in patients with MI. Nevertheless, clinicians should maintain a high level of suspicion when clinical manifestations suggestive of cholesterol embolisation appear after thrombolytic therapy, as the risk of morbidity and mortality can be high.

Abstract
We report the incidence, diagnosis, prevention, and treatment of peripheral vascular complications following coronary interventional procedures as reviewed in the English-language literature. Peripheral vascular complications include hematomas, pseudoaneurysms, arteriovenous fistulae, acute arterial occlusions, cholesterol emboli, and infections that occur with an overall incidence of 1.5-9%. Major predictors of such complications following coronary interventional procedures include advanced age, repeat percutaneous transluminal coronary angioplasty, female gender, and peripheral vascular disease. Minor predictors include level of anticoagulation, use of thrombolytic agents, elevated creatinine levels, low platelet counts, longer periods of anticoagulation, and use of increased sheath size. Ultrasound-guided compression repair of pseudoaneurysms and arteriovenous fistulae are discussed, as are newer methods of treatment such as hemostatic puncture closure devices. Anticipation and early recognition of possible peripheral vascular complications in conjunction with careful attention to the optimal activated clotting time for sheath removal following coronary interventional procedures may translate into fewer vascular complications as well as into shorter and less costly hospital stays.

Abstract
Six cases of suspected multiple cholesterol emboli syndrome were identified by a review of reports contained in the company's records of adverse event reports. Antecedent risk factors in these reports included cardiac catheterization, thrombolytic therapy, translumbar aortography, renal arteriography, subclavian arteriography, abdominal aortography, and heparinization. Unlike the commonly reported subacute presentation, onset occurred during or immediately after catheterization in 5 of the 6 patients reported. Acute renal failure; hypertension; back, leg, and/or abdominal pain; and livedo reticularis were the events most frequently reported. Angiographers should consider multiple cholesterol embolization when multiple organ system dysfunction occurs during or immediately after intraarterial catheterization.

Abstract
A case is presented of lower extremity ischemia related to atheromatous embolization that presumably occurred as a result of passage of an angiographic catheter through the aorta. The patient presented with signs and symptoms pathognomonic for this entity. Emergency physicians need to be aware of this unusual etiology for an ischemic lower extremity.

Abstract
Transesophageal echocardiography (TEE) has enabled detection of the cardiac source of systemic emboli. We report the case of a patient who manifested systemic, multiple embolization in the kidney, skin, and upper gastrointestinal tract following coronary angiography. TEE allowed visualization of the atherosclerotic debris in the thoracic aorta. The clinical picture of the patient was consistent with that of cholesterol embolism. We recommend that patients with extensive atherosclerotic disease should undergo TEE before cardiac catheterization or other invasive procedures involving the aorta are carried out.

Abstract
PURPOSE To determine whether subclinical cholesterol embolization is a frequent sequela of thrombolytic therapy. Case reports of catastrophic cholesterol embolization temporally associated with thrombolytic therapy in 19 patients have suggested a causal relationship. PATIENTS AND METHODS We prospectively followed 60 patients with acute myocardial infarction who underwent coronary bypass surgery within 1 month. Twenty-nine received thrombolytic therapy for myocardial infarction; 31 were treated conservatively. Two muscle biopsy specimens and one skin biopsy specimen were obtained from the vein harvest site at the time of bypass surgery. Paraffin block and frozen sections from each biopsy specimen were analyzed for evidence of cholesterol embolization. RESULTS Cholesterol emboli were found in biopsy specimens from 4 of 29 patients who had undergone thrombolytic therapy (14%) and in 3 of 31 patients who had not undergone thrombolytic therapy (10%, p = NS). Clinical evidence of cholesterol embolization occurred in one patient. Cholesterol emboli were distributed inhomogeneously; they were not observed in any skin biopsy specimen and were never present in more than one muscle biopsy specimen from each patient. CONCLUSIONS The prevalence of cholesterol embolization in patients with acute myocardial infarction treated with thrombolytic therapy is not significantly higher than in those treated without thrombolytic therapy. The cholesterol embolization seen in 12% of our patients was mostly subclinical and was probably spontaneous and/or catheterization induced. Isolated case reports of severe cholesterol embolization temporally associated with thrombolytic therapy do not represent a phenomenon that has widespread subclinical occurrence.

Abstract
Though several animal models of ischemic brain infarction have been developed, no animal model of purely ischemic spinal cord infarction exists. In humans, such paralysis often occurs as a complication of aortic surgery. While working on an animal model of cholesterol embolic renal disease, the authors produced an animal model of ischemic spinal paralysis by direct intraaortic injection of cholesterol suspension. With histologic examination of spinal cords of the paralyzed rats, prominent cholesterol crystals were found obliterating the lumen of the anterior and/or posterior spinal arteries. Spinal cord infarction was seen most prominently in the lateral columns and anterior horns, though other areas also were affected. Permanent paraplegia developed in most rats, but transient paralysis developed in a few, followed by partial or full recovery. This model of spinal infarction in nonanesthetized rats can be used to study the pathophysiology and therapy of spinal infarction.

Abstract
Renal angiography remains the "gold standard" procedure for the detection of renal artery stenosis. However, clinicians often avoid renal angiography because of fears of contrast media-associated nephrotoxicity (CM-AN) and atheroembolism. This review focuses on these potential angiographic complications, with particular emphasis, in the case of CM-AN, on clinical features, incidence, risk factors with an emphasis on pre-existing renal insufficiency and diabetes mellitus, volume of contrast media, low osmolar versus high osmolar contrast media, and prophylaxis. For atheroembolism, areas emphasized are pathology, clinical features, precipitating features, and incidence in various settings. Although the literature contains an abundance of information about CM-AN and atheroembolism, this review identified multiple areas of uncertainty regarding features of both of these complications. For example, additional studies are needed to determine the incidence of CM-AN, both asymptomatic and clinically severe, in patients with a wide range of pre-existing renal insufficiency with and without diabetes mellitus, following low volume digital subtraction renal angiography with low osmolar contrast media. In a similar manner, studies are needed with adequate postcontrast observation periods to determine the true incidence of clinically significant atheroembolism following diagnostic renal angiography and angioplasty and techniques that may modify this complication. Until further knowledge in both of these areas is available, it is difficult to precisely determine the risks of renal angiography and/or angioplasty in the azotemic patient suspected of or having renal ischemic disease using modern radiologic techniques.

Abstract
A seventy-six-year-old man with ischemic heart disease, peripheral vascular disease, and chronic renal failure developed bilateral cyanotic toes, which upon muscle biopsy, were shown to be caused by atheromatous emboli. The probable source was atheromatosis of the abdominal aorta. The toes became gangrenous, but surgical therapy was deferred because the patient was considered a high risk. With lovastatin therapy there was complete healing and except for transient cyanosis related to temporary cessation of therapy, there has been no recurrence for the past thirty months. The possible role of lovastatin in the conservative treatment of this disorder is discussed.

Abstract
We report the occurrence of renal failure due to cholesterol crystal embolization following thrombolytic therapy with intravenous recombinant tissue-type plasminogen activator (t-PA). No invasive vascular procedure had been performed. Although there is one case report of cholesterol crystal embolization following t-PA therapy with only extrarenal manifestations (N Engl J Med 321:1270, 1989), this is the first reported case of atheroembolic acute renal failure following t-PA therapy.
