OBJECTIVE: Cadmium's effect on QRS|T angle has not been studied. An abnormal QRS|T angle deviation may increase the risk for ventricular dysrhythmias. METHODS: We calculated the orientation of spatial QRS|T angle using QRS and T amplitudes of leads V2, V5, V6, and AVF from the National Health and Nutritional Examination Survey III. Cadmium concentration was measured in urine. We fit weighted unadjusted and adjusted logistic regressions to calculate odds ratios and their corresponding 95% confidence intervals...

A 74-year-old woman underwent abdominal computed tomography for screening, and a right large aneurysmal-type renal arteriovenous fistula (AVF) was found incidentally. The venous sac of the renal arteriovenous fistula was enlarged, and coil embolization was considered. To prevent severe complications such as coil migration, pulmonary embolism, and rupture during procedure, coil embolization was approached via both the feeding artery and the draining vein simultaneously, with balloon occlusion of the feeding artery...

BACKGROUND: A multidisciplinary approach and Doppler ultrasound (DU) assessment for the creation and maintenance of arteriovenous fistulas (AVF) for haemodialysis can improve prevalence and patency. The aim of this study was to analyse the impact of a new multidisciplinary vascular access (VA) clinic with routine DU. MATERIAL AND METHODS: We analysed the VA clinic results from 2014 and 2015, before and after the implementation of a multidisciplinary team protocol (vascular surgeon/nephrologist) with routine DU in preoperative mapping and prevalent AVF...

RASA1-related disorders are vascular malformation syndromes characterized by hereditary capillary malformations (CM) with or without arteriovenous malformations (AVM), arteriovenous fistulas (AVF), or Parkes Weber syndrome. The number of cases reported is relatively small; and while the main clinical features are CMs and AVMs/AVFs, the broader phenotypic spectrum caused by variants in the RASA1 gene is still being defined. Here, we report the clinical and molecular findings in 69 unrelated cases with a RASA1 variant identified at ARUP Laboratories...

INTRODUCTION: Renal transplant recipients often maintain their hemodialysis access in the event of future allograft failure. Patients may develop complications related to the unused dialysis access and it also limits vein availability for phlebotomy. Accordingly, a change in the current paradigm may be warranted. This study evaluates the indications for, and safety of, arteriovenous fistula (AVF) removal in patients following successful renal transplantation. METHODS: All patients that underwent AVF excision at a single institution from 2006-2016 were retrospectively reviewed...

Aneurysms associated with arteriovenous fistulas (AVF) are rare but can cause significant morbidity. They are often diagnosed after rupture, pain, or embolization. We describe a unique case of a 35-year-old woman with a large iliac vein aneurysm related to an acquired AVF incidentally discovered on ultrasound during pregnancy. She had a diagnosis of "idiopathic" pulmonary hypertension for several years. This report details the diagnosis and treatment with an arterial stent graft that was effective in decreasing the size of the venous aneurysm and reversing the systemic changes associated with the disease...

The pathophysiology of arteriovenous fistula (AVF) maturation failure is not completely understood but impaired outward remodeling (OR) and intimal hyperplasia are thought to be contributors. This adverse vascular response after AVF surgery results from interplay between vascular smooth muscle cells (VSMCs), the extracellular matrix (ECM), and inflammatory cells. Relaxin (RLN) is a hormone that acts on the vasculature via interaction with RLN/insulin-like peptide family receptor 1 (RXFP1), resulting in vasodilatation, ECM remodeling, and decreased inflammation...

BACKGROUND: Peritoneal dialysis (PD) is an effective renal replacement technique. However, every year a considerable number of patients are transferred to hemodialysis (HD). Our aim was to identify those at risk, in order to place an arteriovenous fistula (AVF). METHODS: Case-control study enrolling all prevalent patients in 2014 and 2015 in our clinic. Groups: 72 case patients who were transferred definitively to HD, 111 control patients (remaining on PD, transplanted, recovered renal function, or deceased)...

BACKGROUND: Right ventricular (RV) dysfunction is associated with increased risk of heart failure and mortality in end stage renal disease (ESRD) patients. Accumulating evidence suggests an association between atriovenous fistula (AVF) and RV dysfunction; however, there is no adequate data on the relation between AVF characteristics and risk of RV dysfunction after AVF creation. METHODS: The study included 30 ESRD patients (median age: 44years, 17 male) who had their first autogenous mature AVF...

BACKGROUND: Iatrogenic injuries of the renal artery include pseudoaneurysms (PSA) and pseudoaneurysms with arteriovenous fistula (PSA + AVF). They can cause hematuria, anemization and flank pain. Endovascular treatment is recommended due to its effectiveness. OBJECTIVE: To assess the potential difference between the embolization of iatrogenic renal PSA and iatrogenic renal PSA + AVF, in terms of technical and clinical success rate, procedure complexity and impact on the renal function...

BACKGROUND: Patients with atrial myocardial infarction (ATMI) have frequent cardiac and noncardiac complications. However, ATMI is uncommonly diagnosed because of its nonspecific electrocardiographic changes. HYPOTHESIS: Our objective was to analyze the electrocardiographic characteristic of ATMI in patients with inferior STEMI. METHODS: A total of 932 patients who underwent coronary angiography were evaluated. Thirty-nine patients with ATMI and 33 patients without ATMI with inferior STEMI were recruited for a retrospective study...

Arteriovenous fistulas (AVFs) are abnormal shunts between the arterial and venous vascular systems. These usually produce ocular pain, increased intraocular pressure (IOP), and diplopia. Less frequently, they may cause retinal changes with visual impairment. Our purpose is to illustrate different retinal manifestations of AVF. We report the multimodal imaging study of three cases with retinal changes due to AVF, showing neurosensory retinal detachment, macular oedema, and macular ischemia. In conclusion, AVF may appear with different ophthalmic alterations...

Standard salvage procedures for occuluded autologous arteriovenous fistula (AVF) in a hemodialysis patient are endovascular and/or surgical therapy. When endovascular therapy and thrombectomy prove unsuccessful, it is most likely that creating a new AVF or arteriovenous graft will be considered. However, if the occuluded venous part is short, we have adopted an operative technique for repair of AVF by removal of the occluded short venous part and venovenous end-to-end anastomosis. To our knowledge, the efficacy and clinical course of restoration of AVF by the technique have not been reported to date...

N-butyl-2 cyanoacrylate (NBCA) is a liquid embolic material that is widely used in various endovascular procedures because of its permanent and rapid vascular occluding effect regardless of the coagulation profile of the patient. However, NBCA migration to unintended vessels may result in serious complications. This report describes the retrieval of a migrated NBCA cast from the transverse-sigmoid sinus during dural arteriovenous fistula embolization using a transvenous snaring technique.
