atheroembolism kidney

Marie E Perrone, Anthony Chang, Kammi J Henriksen
Kidney diseases affect many hospitalized patients and contribute to morbidity and mortality. Therefore, kidney disease should be prevalent, but the frequency and spectrum of medical renal pathology in autopsy specimens has not been well documented. We sought to determine the spectrum of medical renal pathology in adult autopsy specimens and the frequency of overlooked diagnoses. We reviewed the hematoxylin- and eosin-stained kidney sections from 140 adult autopsies performed at a large teaching hospital over a 2-year period...

Objective: The present study aimed to determine the effect of an increasing number of predisposing atheroembolic risk factors on the development of chronic kidney disease (CKD) after partial nephrectomy (PN) in patients with T1-stage renal cell carcinoma (RCC). Methods: The study included 147 patients with T1-stage RCC with a normal contralateral kidney and without preoperative CKD, who underwent open (OPN, N = 83, 56.5%) or laparoscopic PN (LPN, N = 64, 43.5%) between 2003 and 2014...

Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis...

Vascular chronic diseases represent one of the leading causes of end-stage renal disease in incident dialysis patients. B-Mode ultrasound (US) and color Doppler (CD) have a high sensitivity and specificity in the diagnosis of vascular chronic diseases. US and CD should be used to identify subjects in the high risk population who are affected by main renal artery stenosis (RAS) and to identify and characterize patients without RAS who have chronic ischemic nephropathy caused by nephroangiosclerosis and/or atheroembolic disease...

INTRODUCTION: When ischemic events ascribable to microembolization occur during open repair of proximal abdominal aortic aneurysms, a likely origin of atheroembolism is not always found. PRESENTATION OF CASE: A 78-year old man with enlargement of the entire aorta underwent open repair for a pararenal abdominal aortic aneurysm using supraceliac aortic clamping for 20min. Then the graft was clamped, the supraceliac clamp was removed, and the distal and right renal anastomoses were also completed...

BACKGROUND: Atheroembolic renal disease, due to dislodgement of cholesterol crystals during maneuvering of a large catheter across the aorta and deployment of the transcatheter prosthesis within a calcified aortic valve, may be one of the pathophysiological mechanisms of acute kidney injury (AKI) complicating transcatheter aortic valve implantation (TAVI). OBJECTIVE: To investigate the association between the atherosclerotic burden and plaque characteristics of the aortic valve and thoracic aorta, evaluated with multidetector CT (MDCT), and the occurrence of AKI after TAVI...

Kidneys and skin are seldom considered associated, but their relationship is more closer than generally believed. In some immunological diseases (SLE...) and genetic syndromes (tuberous sclerosis, Fabrys disease...) the cutaneous manifestations are integral parts of the clinical picture. In advanced uremia, besides the well-known itching skin lesions, calciphylaxis may appear, a typical example of cutaneous involvement secondary to the metabolic complications (calcium-phosphate imbalance) of the renal disease...

Dabigatran is a direct thrombin inhibitor that reduces the risk of systemic embolism in patients with nonvalvular atrial fibrillation. We report a case of an elderly man who developed unexplained rapid decline in renal function 6 weeks after starting dabigatran. A renal biopsy was planned to find out the etiology of acute renal failure, but the patient has significantly prolonged coagulation parameters despite holding medication for 5 days per manufacturer's recommendation. He was started on hemodialysis due to worsening renal function and to ensure dabigatran clearance before renal biopsy...

OBJECTIVE: Aortic sources of peripheral and visceral embolization remain challenging to treat. The safety of stent graft coverage continues to be debated. This study reports the outcomes of stent coverage of these complex lesions. METHODS: Hospital records were retrospectively reviewed for patients undergoing aortic stenting between 2006 and 2013 for visceral and peripheral embolic disease. Renal function, method of coverage, and mortality after stent grafting were reviewed...

BACKGROUND: Contrast-induced nephropathy (CI-AKI) is a complication of diagnostic/therapeutic hemodynamic procedures in cardiology, which may also cause renal cholesterolinic atheroembolism. Despite the 
severe clinical impact of these complications, there is no optimal therapy for preventing and treating them. We suggest a short course of high-dose steroids as an effective preventive measure. METHODS: Patients at risk of CI-AKI (n = 38) undergoing cardiovascular procedures were assigned 1:1 to 1 of 2 experimental arms (prednisone+hydration vs...

A 69-year-old man was admitted to our hospital with severe hypertension and rapidly worsening renal function. He presented with a 10-year history of chronic renal failure caused by bilateral ureteral obstruction due to retroperitoneal fibrosis. Magnetic resonance angiography and Doppler ultrasonography suggested severe right renal artery stenosis (RAS). Renal angiography revealed 99% stenosis at the ostium of the right renal artery. We performed percutaneous transluminal renal angioplasty (PTRA) with the support of intravascular ultrasound to decrease the amount of contrast agent needed...

In western countries, the risk of cardiovascular disease has increased considerably in recent decades. This trend has been paralleled by an increase in cases of atherosclerotic renal disease, which is related to the improved prognosis of cardiovascular diseases, aging, and the increasing mean age of the general population. It is reasonable to expect that in the near future, there will be a sharp increase in the number of elderly patients with atherosclerotic vascular disease in chronic dialysis programs. The result will be a dramatic rise in the social and economic costs of dialysis that could constitute a true clinical emergency...

Cholesterol atheroembolism (CAE) is a systemic disorder whose incidence has increased in recent decades and that presents high morbidity and mortality. Although several therapeutic alternatives have been reported, there is no consensus about the best treatment for this disease. In this paper we report the case of a patient with CAE with skin, bowel and kidney involvement who presented a good response to combined therapy with steroids and prostaglandin analogues. Although there are no conclusive studies, we recommend this therapeutic alternative in the management of CAE with organic failure...

Atheromatous renal disease is the major cause of renal insufficiency in the elderly, and cholesterol embolism is a manifestation of this disease. Cholesterol embolism occurs in patients suffering from diffuse erosive atherosclerosis, usually after triggering causes, such as aortic surgery, arterial invasive procedures (angiography, left heart catheterization and coronary angioplasty) and anticoagulant or thrombolytic therapy. It is characterized by occlusion of small arteries with cholesterol emboli deriving from eroded atheromatous plaques of the aorta or large feeder arteries...

The Piedmont Group of Clinical Nephrology has compared the activity of 18 nephrology centers in the region Piedmont/Valle d'Aosta with regard to renal biopsy (RB). Data on the RBs performed in every nephrology unit, taking into account their entire experience (in some cases spanning more than 30 years), were analyzed. 3396 RBs were performed between 1996 and 2011. Thirty to forty percent were done in patients aged >-65 years (1568 in patients >-65 years, 29 in patients >-85 years). 598 BRs were performed in children over the last 20 years...

INTRODUCTION: The topic of contrast-induced nephropathy (CIN) has been receiving an enormous amount of interest in recent times; however, this review is not a review of what CIN is, but what it is not. METHODS: We will review the main topics demonstrating that the post hoc ergo propter hoc assumption that renal impairment occurring after contrast medium (CM) infusion is necessarily because of it, is wrong, as we are dealing with different diseases, depending on the way the CM is administered and on the type of patient...

OBJECTIVES: We sought to measure angiographic renal frame counts (RFC), as a quantitative angiographic assessment of renal blood flow, to evaluate microvascular compromise due to atheroembolism associated with RAS. BACKGROUND: Atheroembolism associated with renal artery stenting (RAS) has been implicated as a cause for worsening renal function following successful intervention. Use of a distal embolic protection device (EPD) during RAS has been shown to be safe with debris capture in a high percentage of cases...

PURPOSE OF REVIEW: To describe cholesterol embolization syndrome (CES) and its risk factors, pathophysiology, clinical presentation, diagnosis and treatment. RECENT FINDINGS: To date, no specific diagnostic test (other than biopsy) for CES has been developed. Effective treatments for CES are yet to be developed. SUMMARY: CES (also referred to as cholesterol crystal embolization, atheromatous embolization or atheroembolism) occurs when cholesterol crystals and other contents of an atherosclerotic plaque embolize from a large proximal artery to smaller distal arteries, causing ischemic end-organ damage...
