Introduction: Patients having End Stage Renal Disease (ESRD) require kidney replacement therapy for survival. As transplantation is expensive, haemodialysis using an Arteriovenous Fistula (AVF) the preferred mode of management. Preoperative assessment blood vessels Doppler Ultrasonography (DUS) in creation efficient AVF. Aim: To use DUS evaluation and mapping vessels, selection AVF construction...

Heme oxygenase-2 (HO-2), the constitutive isoform of the heme-degrading enzyme heme oxygenase, may serve as an anti-inflammatory vasorelaxant, in part, by generating carbon monoxide. Arteriovenous fistulas (AVFs) are employed as hemodialysis vascular accesses because they provide an accessible, high-blood-flow vascular segment. We examined the role of vascular expression of HO-2 in AVF function...

Background and objectives: The kidneys of chronic kidney disease (CKD) patients do not have enough function and hemodialysis (HD) is a common procedure for their treatment. HD requires vascular access surgery (VAS) and arteriovenous fistula (AVF) is a low-complication method in VAS. However, different rates of AVF failure have been reported worldwide which can cause repeating s...

Architectural vulnerability factor (AVF) is the probability that a transient fault in a bit, gate, or transistor becomes a user-visible error. AVFs vary widely across time, applications, and bits. Usually AVFs averaged over time and across applications are used to compute the overall soft error rate of a processor. Average AVFs, however, cannot express the short-term vulnerability variations of...

Hemodialysis (HD) is the most commonly-used renal replacement therapy for patients with end-stage renal disease worldwide. Arterio-venous fistula (AVF) is the vascular access of choice for HD patients with lowest risk of infection and thrombosis. In addition to environmental factors, genetic factors may also contribute to malfunction of AVF. Previous studies have demonstrated the effect of geno...

BACKGROUND Access-related problems are one of the major causes of morbidity in elderly patients with chronic kidney disease. The aim of this study was to assess potential risks and benefits in elderly patients comparing forearm arteriovenous fistula (AVF) and perforating vein AVF below the elbow for primary vascular access. METHODS A retrospective comparison of elderly patients (65.7 ± 9.3 ye...

BACKGROUND The arteriovenous fistula (AVF) is the preferred form of hemodialysis access for patients with chronic kidney disease. However, AVFs are associated with significant problems including high incidence of both early and late failures, usually attributed to inadequate venous arterialization and neointimal hyperplasia, respectively. Understanding the cellular basis of venous remodeling in...

Alteration of hemodynamic loading induces remodeling that includes changes in myocardial properties and extracellular matrix structure. We investigated the hypothesis that cardiac hypertrophy due to volume overload produces changes in myocardial diastolic mechanics and stiffness that are in part due to alterations in advanced glycation end-product (AGE) collagen cross-linking. Rats developed vo...

The antiviral factor (AVF) from virus-infected plants, purified on polyacrylamide gels, could be labelled with radioactive phosphorus and its activity could be eluted from the gels. The radioactivity and the antiviral activity were co-purified and thus co-electrophoresed; hence, the previously reported radioactive zone (Antignus, Sela & Harpaz, 1975) can be regarded as AVF. The production of AV...

Nongalenic arteriovenous fistula (NGAVF)also known as intracranial pial arteriovenous fistula (AVF), cerebral AVF, or brain AVF is a rare vascular malformation.There are few retrospective case series describing their epidemiological, clinical and radiographic characteristics as well as technical elements of treatment. Combined transarterial and transvenous embolization of a 4 month old female w...
