BACKGROUND An upper limb arteriovenous (AV) fistula is the access of choice for haemodialysis (HD). There have been few reports of saphenofemoral AV fistulas (SFAVF) over the last 10-20 years because of previous suggestions of poor patencies and needling difficulties. Here, we describe our clinical experience with SFAVF. METHODS SFAVFs were evaluated using the following variables: immediate r...

BACKGROUND Arteriovenous (AV) grafts in haemodialysis patients usually fail due to thrombosis or infection. There is limited information on whether graft outcomes in HIV-positive haemodialysis patients differ from those in HIV-negative controls. METHODS Using a prospective, computerized vascular access database, we identified retrospectively 15 HIV-positive dialysis patients having a graft pl...

BACKGROUND A precise, non-invasive, non-toxic, repeatable, convenient and inexpensive follow-up of renal transplants, especially following biopsies, is in the interest of nephrologists. Formerly, the rate of biopsies leading to AV fistulas had been underestimated. Imaging procedures suited to a detailed judgement of these vascular malformations are to be assessed. METHODS Three-dimensional (3...

An idiopathic renal arteriovenous (AV) fistula is a rare malformation of the kidney that may present insidiously with heart failure or hematuria. The treatment may be challenging due to large fistula size that may limit endovascular management. The authors report a case of an 85-year-old Caucasian woman who presented with acute heart failure and was found to have a right renal AV fistula. Since...

The purposes of this study were to review historical changes in the classification of spinal arteriovenous (AV) shunts and to propose a practical classification system. The associated literature regarding the classification of spinal AV shunts was reviewed in the angiography era between 1967 and 2015. The classification systems of spinal AV shunts and a proposed classification system were prese...

Hemodialysis vascular access recommendations promote arteriovenous (AV) fistulas first; however, it may not be the best approach for all hemodialysis patients, because likelihood of successful fistula placement, procedure-related and subsequent costs, and patient survival modify the optimal access choice. We performed a decision analysis evaluating AV fistula, AV graft, and central venous cathe...

Efforts during the past 5 to 10 years to increase the proportion of patients in the United States who receive maintenance hemodialysis via a native arteriovenous (AV) fistula have been successful. In 2008, 55% of prevalent patients in the United State were undergoing dialysis via a fistula compared with only 35% in 2003 (1,2). Despite this substantial progress, challenges remain, among the most...

Vascular accesses consist of permanent arteriovenous (AV) accesses (autogenous fistulas and synthetic grafts) and venous accesses (central venous catheters [CVCs]). AV accesses have fewer complications than venous accesses, and are therefore the preferred hemodialysis access. An important additional issue is whether the type of access influences adequacy of dialysis (i.e. Kt/V). Key limiting fa...

Proper vascular access function is required for efficient dialysis. With an unchanged incidence of patients undergoing renal replacement therapy and an increasing life expectancy, an increase in the insufficiency of dialysis accesses has accordingly been seen [1]. By maintaining long-term function, the use of dialysis catheters associated with a higher mortality rate can be avoided [2]. The mos...
