BACKGROUND: Arteriovenous accesses (AVA) in patients performing hemodialysis (HD) are labeled "permanent" for AV fistulas (AVF) or grafts (AVG) and "temporary" for tunneled central venous catheters (TCVC). Durability and outcomes of permanent vascular accesses based on the sequence in which they were placed or used receives little attention. This study analyzed longitudinal transitions between TCVC-based and AVA-based HD outcomes according to the order of placement. METHODS: All 391 patients initiating chronic HD via a TCVC between 2012 and 2013 at 12 outpatient academic dialysis units were included in this study...

BACKGROUND AND OBJECTIVES: Fistulas, the preferred form of hemodialysis access, are difficult to establish and maintain. We examined the effect of a multidisciplinary vascular access team, including nurses, surgeons, and radiologists, on the probability of using a fistula catheter-free, and rates of access-related procedures in incident patients receiving hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We examined vascular access outcomes in the first year of hemodialysis treatment before (2004-2005, preteam period) and after the implementation of an access team (2006-2008, early-team period; 2009-2011, late-team period) in the Calgary Health Region, Canada...

OBJECTIVE: This study reviewed our experience with proximal radial artery-based arteriovenous fistulas (PRA-AVFs) for hemodialysis vascular access, evaluating characteristics of the patients, functional patency, risk of steal syndrome, survival of the patient, and technical considerations. METHODS: We retrospectively analyzed our database of consecutive patients, identifying those individuals with a PRA-AVF created during a 12-year period. In addition to physical examination, all patients underwent ultrasound vessel mapping by the operating surgeon, identifying the PRA-AVF configuration and outflow target most likely to succeed...

BACKGROUND: Arteriovenous fistula (AVF), permanent catheter (PC), and vascular graft are three vascular access types used for hemodialysis procedure. Due to insufficient reliable information on the comparison between AVF and PC, this study was conducted to compare AVF and PC regarding dialysis adequacy. MATERIALS AND METHODS: This prospective study was carried out from March, 2013 to September, 2013. In this study, 76 hemodialysis patients were enrolled and assigned to two unequal groups of AVF and PC...

Objective With the implementation of the K-DOQI guidelines, more patients are in need of long-term dialysis catheters until maturation of the arteriovenous fistula. However, on occasion, when placing a tunneled cuffed catheter for hemodialysis, we have encountered difficulty with passing the guidewire in spite of demonstration of a patent cervical portion of the internal jugular vein on duplex. Herein, we review our experience with intraoperative venoplasty for placement of Tesio™ catheters (Medcomp Harleysville, PA)...

Autogenous arteriovenous fistulas (AVF) are the preferred access for hemodialysis. AVF occasionally develop venous aneurysms and we report a modified staple aneurysmorrhaphy technique for treatment. Briefly, the lateral wall of the venous aneurysm is dissected and a longitudinal staple resection performed. Adjunct procedures include inflow banding and outflow venous angioplasty with possible stenting. In this initial experience, 20 aneurysms were resected in 17 patients. The average AVF age at time of repair was 5...

We report here a typical case of a patient on hemodialysis (HD) for end-stage renal disease (ESRD) in India that highlights some of the management issues encountered in a country with an enormous burden of ESRD and major challenges of underdialysis and management of comorbidities. The patient, a 42-year-old multiparous woman with chronic kidney disease (CKD) stage V, type 2 diabetes mellitus, and hypertension is a homemaker from a middle-class family, living in a large city, with no family history of CKD. From May 2013 to December 2016, she has been receiving twice-weekly maintenance HD for 4 h (intermittent HD); access was via an internal jugular line initially and then via a left brachiocephalic arteriovenous fistula (AVF) from late June 2013...

In hemodialysis patients the principal cause of arteriovenous fistula dysfunction is stenosis. Matrix-metalloproteinase-2 is implicated in the pathophysiological mechanism of stenosis development. Our study tried to assess the clinical impact of this protease on arteriovenous fistula survival. Seventy-nine prevalent dialysis patients with functional arteriovenous fistulas were included in the study. The presence of stenosis and the serum levels of matrix-metalloproteinase-2 were determined at the beginning of the study...

OBJECTIVES: Vascular occlusion of hemodialysis arteriovenous access (AVA) using an Amplatzer vascular plug (AVP; St. Jude Medical, St. Paul, MN, USA) is an arising and alternative practice in selected patients; however, few reported cases can be found in the literature. Herein, we report on our experience with endovascular treatment of complicated AVA. MATERIALS AND METHODS: From September 2015 to December 2016, 3 patients at our clinic underwent an occlusion of hemodialysis AVA with 2 different Amplatzer vascular plugs: 2 patients with type II and 1 patient with type IV...

BACKGROUND: Despite improved health outcomes associated with arteriovenous fistulas, 80% of Americans initiate hemodialysis using a catheter, influenced by low socioeconomic status among other factors. Risk factors for incident catheter use in safety-net populations are unknown. Our objective was to identify factors associated with incident catheter use among hemodialysis patients at one safety-net hospital, with a goal of informing fistula placement initiatives targeted at safety-net populations more generally...

Arteriovenous access dysfunction is a major cause of morbidity for hemodialysis patients. The pathophysiology of arteriovenous fistula (AVF) maturation failure is associated with inflammation, impaired outward remodeling (OR) and intimal hyperplasia. RP105 is a critical physiologic regulator of TLR4 signaling in numerous cell types. In the present study, we investigated the impact of RP105 on AVF maturation, and defined cell-specific effects of RP105 on macrophages and vascular smooth muscle cells (VSMCs). Overall, RP105(-/-) mice displayed a 26% decrease in venous OR...

Hemodialysis catheters are associated with higher risks of complications compared to arteriovenous fistulas and grafts. Some common complications of dialysis catheters include infection, thrombus formation, central venous stenosis, and mechanical dysfunction. Rarely, catheters can become firmly adhered to a vessel wall. Catheter adhesion is a serious complication that can impact the delivery of safe and effective dialysis to affected patients. Adherent catheters commonly present insidiously with no overt diagnostic signs and symptoms or antecedent catheter malfunction...

INTRODUCTION: Contemporary dogma has classically attributed hand dysfunction following hemodialysis arteriovenous fistula (AVF) placement to regional ischemia. We hypothesize that hemodynamic perturbations alone do not entirely explain the postoperative changes in hand function and, furthermore, that various elements of hand function are differentially affected following surgery. METHODS: Bilateral wrist and digital pressures and upper extremity nerve conduction tests were recorded preoperatively and at 6 weeks and 6 months following upper extremity AVF construction in 46 patients...

BACKGROUND: Arteriovenous fistulae are the currently recommended gold standard vascular access modality for haemodialysis because of their prolonged patency, improved durability, and low risk of infection for those that mature. However, notable disadvantages are observed in terms of protracted maturation time, associated high rates of catheter use, and substantial abandonment rates. The aim of this study was to quantitatively summarize the outcomes of fistula patency, infection, maturation, and abandonment published in the scientific literature...

REVIEW
Ja Young Lee, Young Ok Kim
The radiocephalic arteriovenous fistula (AVF) provides optimal vascular access for hemodialysis; it has a higher long-term patency rate and fewer complications than other vascular access methods. However, the AVF has a high primary failure rate. The presence of small-diameter vessels at anastomosis sites is an important risk factor for AVF failure. However, in a recent study, despite selecting an adequate artery and vein for creating an AVF by routine preoperative vascular mapping, AVF maturation and primary failure occurred...

OBJECTIVE: In addition to age and comorbidities, health-related quality of life (HRQOL) is known to predict mortality in hemodialysis (HD) patients. Understanding the association of vascular access type with HRQOL can help surgeons to provide patient-centered dialysis access recommendations. We sought to understand the impact of HD access type on HRQOL. METHODS: We conducted a cross-sectional prospective study of community-dwelling prevalent HD patients in Pittsburgh, Pennsylvania...

The arteriovenous fistula is the preferred type of hemodialysis vascular access for patients with end-stage renal disease, but a high proportion of newly created fistulas fail to mature for use. Stenosis caused by neointimal hyperplasia often is present in fistulas with maturation failure, suggesting that local mechanisms controlling vascular smooth muscle cell (SMC) migration and proliferation are important contributors to maturation failure. SMCs cultured from explants of vein tissue obtained at the time of fistula creation from 19 patients with end-stage renal disease were studied to determine whether smooth muscle responsiveness to nitric oxide is associated with fistula maturation outcomes...
