The number of end stage of renal disease patients that need dialysis or renal transplantation increased in the world. Insertion and maintenance functional vascular access remain the challenging problem. Arteriovenous fistula is the common access for dialysis but complication and its failure is the main problem. The aim of this study is to evaluate patients with arteriovenous fistula during 4 ye...

BACKGROUND Hemodialysis used as renal replacement therapy requires a well-functioning vascular access. Arterio-venous fistula (AVF) created on the forearm is the best vascular access, but it also reveals numerous complications such as: lack of fistula maturation and hemodynamically significant stenoses. Many risk factors of fistula dysfunction are still not identified. MATERIAL/METHODS Radial...

The Fistula First Initiative set a goal of 66% arteriovenous (AV) fistula-based access among US hemodialysis patients. This study modeled the impact of achieving the target AV fistula placement rate on Medicare expenditures and on dialysis patient survival and also reviewed economic disincentives for providers that will inhibit achieving this target. The model projects lifetime costs and surviv...

BACKGROUND Progressive narrowing of the venous part of dialysis fistulae is caused by hemodynamic and inflammatory factors. OBJECTIVES The pathogenic and clinical determinants of deterioration of the functioning of arteriovenous fistulae in chronically hemodialyzed patients were evaluated. MATERIAL AND METHODS The hemodynamic parameters and the activity of inflammatory growth factors in the...

The primary aim of this chapter is to understand the importance of placement and maintenance of arteriovenous fistula (AVF) in the patients with advanced renal failure prior to the need for dialysis. Vascular access complications contribute significantly to the morbidity and mortality associated with end-stage renal disease patients on hemodialysis. The major concern this publication will addre...

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...

BACKGROUND There is marked variation in the use of the arteriovenous fistula (AVF) across programmes, regions and countries not explained by differences in patient demographics or comorbidities. The lack of clear criteria of who should or should not get a fistula may contribute to this, as well as barriers to creating AVFs. METHODS We conducted a survey of Canadian and American nephrologists ...

Good vascular access is an essential component for hemodialysis (HD). Studies in patterns of vascular accesses used for HD are very few. Eighty two (male 55, female 27) patients attending HD unit of Nepal Medical College and Teaching Hospital (NMCTH) over a period of one year were enrolled for the study. Average age was 46.12 years. Seventy four patients (90.0%) were suffering from chronic kidn...

BACKGROUND AND OBJECTIVES Concern about primary fistula failure may contribute to the underuse of arteriovenous fistula. The objective of this study was to investigate the baseline clinical parameters associated with primary fistula success. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Consecutive incident patients who commenced dialysis during a 28-mo period in a regional renal program were...
