PURPOSE: Vascular calcification is common in chronic kidney disease (CKD) and predicts poor patient outcomes. While computed tomography is the gold standard for evaluation of vascular calcification, plain radiograph offers a simpler and less costly alternative. The calcification of abdominal aorta, iliac and femoral arteries has been evaluated by plain radiograph, but the data on their outcome predictabilities are still limited. The present study investigated the role of abdominal aortic calcification (AAC) and pelvic arterial calcification (PAC) in predicting overall morality in non-dialysis CKD stages 2-5 (CKD 2-5), maintenance hemodialysis (HD) and long-term kidney transplant (KT) patients...

In recent years, the frequency of high-risk kidney transplantations has increased. We report a case in which a 72-year-old man with various severe comorbidities (prostate cancer, diabetes mellitus, complete atrioventricular block, coronary artery stenosis, severe stenosis of the popliteal arteries, and severe calcification of the iliac arteries) who received an orthotopic kidney transplantation. To prevent the occurrence of acute limb ischemia due to the steal phenomenon (caused by the kidney graft), we decided that a heterotopic kidney transplantation involving the iliac arteries was not an appropriate option...

BACKGROUND: Kidney recipients are increasingly older with arterial disease and extended arterial calcifications. In a kidney transplantation population, the prognosis value of aortic and iliac calcifications remains poorly explored. We aimed to assess the impact of pretransplantation aortoiliac vascular calcifications on patients, grafts survival, and cardiovascular events. METHODS: This retrospective study included kidney transplantation patients from 2006 to 2012 for whom we had available presurgery abdominal computed tomography results (n = 100)...

Based on native CT scans of the pelvic region using a standardized calcification score, evaluation of iliac vascular calcification was performed between 2008 and 2012 prior to listing for renal transplantation in 205 patients with chronic kidney disease. Vascular calcification showed a decrease from proximal to distal. The difference between the degree of calcification in the common iliac artery and in the external iliac artery was significant (P<.001). Risk factors for total iliac vascular calcification were age, smoking, sex, underlying renal disease, and diabetes...

OBJECTIVE: The objective of our study was to assess whether the degree and distribution of iliac artery calcifications as determined by a CT-based calcium scoring system correlates with outcomes after renal transplant. MATERIALS AND METHODS: A retrospective review of renal transplant recipients who underwent CT of the pelvis within 2 years before surgery yielded 131 patients: 75 men and 56 women with a mean age of 52 years. Three radiologists assigned a separate semiquantitative score for calcification length, circumferential involvement, and morphology for the common iliac arteries and for the external iliac arteries...

Kidney transplantation originating from the hepatic artery has not previously been reported. Herein, we report a third kidney transplantation with the common hepatic artery as inflow. A 62-year-old male with chronic renal failure due to polycystic kidney disease was proposed to a third kidney transplantation. CT-scan showed diffuse calcification of the aorto-iliac axis and the splenic artery. The common hepatic artery was the only artery suitable for anastomosis and as such was chosen as the inflow for retransplantation...

OBJECTIVE: To describe the use of vascular conduits (donor iliac artery or saphenous vein) in renal transplantation recipients with extensive aortoiliac calcification. MATERIALS AND METHODS: Vascular conduits were used in 10 renal transplants with severe vascular calcification at Cleveland Clinic from 2009 to 2013. Both iliac artery (N = 8) and saphenous vein (N = 2) grafts were used. Surgical technique is reviewed in detail. Surgical complications, patency on renal transplant ultrasonography, and serum creatinine level at multiple time points were reviewed...

BACKGROUND: The clinical significance of preexisting microcalcification in the iliac artery is undetermined in renal transplant recipients. METHODS: We obtained iliac artery segments from 90 transplant recipients at the time of renal transplantation and performed von Kossa staining for microcalcification. The clinical significance of intimal microcalcification was evaluated with allograft survival rate, rate of graft function decline, and composite of any cardiovascular event or patient death...

BACKGROUND: Peripheral vascular disease and major extremity amputation are common in patients with established renal failure and are associated with considerable morbidity. Several studies have shown high rates of amputation following simultaneous pancreas-kidney transplantation, but there is minimal literature on the incidence of amputation following renal transplantation. Furthermore, there is little evidence regarding the best method of predicting which patients might be at risk of developing peripheral vascular complications after transplantation...

BACKGROUND: Cardiovascular disease in chronic kidney disease (CKD) has peculiar characteristics. The aim of this study was to analyze atherosclerosis, vascular calcification and nitration in arteries from CKD patients. METHODS: External iliac and renal artery segments from 27 stage 5 CKD patients and 25 donor controls, respectively, were collected during the transplantation procedure. RESULTS: CKD patients presented a significantly higher degree of lesion...

The pretransplant imaging evaluation of recipients is mainly achieved with CT and has two objectives: detection of iliac artery calcifications that may have an impact on the site of the transplant and the type of arterial anastomosis; detection of a primary malignancy that would be a contraindication to transplantation. The pretransplant imaging evaluation of living donors relies on noninvasive techniques. CT angiography and MR angiography both allow the simultaneous evaluation of arteries, excretory tract and renal parenchyma...

BACKGROUND: It is unknown whether if a plain X-ray of the iliac arteries (pelvic X-ray) is a reliable tool to detect calcifications and predict vascular complications. METHODS: In a prospective study, a pelvic X-ray was performed before transplantation in patients without evidence of peripheral vascular disease (n = 109) and vascular calcifications were scored. Vascular calcifications in the iliac arteries and complications were scored by the transplant surgeon during the operation (gold standard)...

Little is known about the proportion of renal transplant candidates who are considered ineligible by the transplant center, the reasons of their ineligibility and their survival during dialysis. In this retrospective, single-center study of 445 adult patients referred between 2001 and 2006, 36 (8%) were deemed ineligible for medical contraindications. The leading reason was cardiovascular (CV) (75%), specifically aorto-iliac, and/or limb vessels atheromatosis or calcifications; ischemic heart disease; or a combination thereof...

BACKGROUND: Coral reef aorta (CRA) is described as rock-hard calcifications in the visceral part of the aorta. These heavily calcified plaques grow into the lumen and can cause significant stenoses, leading to malperfusion of the lower limbs, visceral ischaemia or hypertension due to renal ischaemia. PATIENTS/METHODS: From 1/1984 to 11/2008, 80 patients (26 m, 54 f, mean age 61.6, range 14 to 86 years) underwent treatment in the Department of Vascular Surgery and Kidney Transplantation, Heinrich-Heine-University Hospital for CRA...

Patients undergoing hemodialysis have a lower survival rate than those who receive a kidney transplant. Mortality among hemodialysis patients is approximately 14.5% compared with 1.5% for transplant recipients. One of the exclusion criteria for renal transplant is severe iliac artery calcification. We performed an aortofemoral bypass in these patients to make them eligible for renal transplantation. Eleven patients were selected to receive an aortofemoral bypass. All had severe calcification of iliac arteries...

Ipsilateral placement of double kidneys from marginal donors into older recipients may reduce the stress of the operation on the patient and allow for extension of the utility of older donor kidneys. A separate bench preparation of the kidneys is performed to aid in assessing the quality of the kidneys before placement in the recipient. Multiple renal arteries and proximal calcifications may require extracorporeal anastomosis or multiple anastomoses in the recipient depending on length and size of the renal vessels...

A 74-year male patient was admitted to our department with a left renal artery aneurysm (RAA). It was detected by a computed tomography (CT) scan while performing an examination for hypertension. The diameter of the aneurysm was 25 mm. There was no evidence of calcification. Selective left renal angiography and a 3-dimensional (3D)-CT image revealed a saccular renal aneurysm in the left main renal artery. Because of the risk of rupture, autotransplantation of the left kidney to the left iliac fossa was performed after resecting the aneurysm and reconstructing the left artery under bench surgery...

UNLABELLED: The increased scope of renal transplant indications has lead to a larger number of recipients with vascular problems due to arterial calcifications in the iliac region. Compared to magnetic resonance and conventional arteriography, helical computed tomography angiography (HCTA) accurately depicts arterial diseases, including the location and extent of arterial calcification. The objective of this study was to assess the value of HCTA with maximum-intensity-projection (MIP) reconstruction to evaluate iliac arterial calcifications and stenosis among candidates for renal transplantation...

BACKGROUND: The relationship between primary renal disease and arterial wall changes in paediatric haemodialysis patients has been little studied. The aim of the present work was to determine the influence of primary renal disease on arterial wall pathology in uraemic paediatric patients. METHODS: Twelve paediatric haemodialysis patients (seven girls, five boys) aged 11-17 years were included in the study. The primary renal diseases were urinary malformations in six patients (uropathy group) and acquired glomerular diseases (glomerulopathy group) in six patients...
