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: 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...

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...

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...

PURPOSE: Higher health-related quality of life (HRQOL) in dialysis patients has been associated with fewer hospitalizations and lower mortality. Since Arab patients on dialysis have better survival rates than Jewish patients, we hypothesized that they would have higher HRQOL. We also studied the impact of several risk factors on HRQOL in each population. METHODS: Based on a national dialysis registry, patients from 64 hemodialysis units were recruited to participate...

REVIEW
Hector Ferral, Marc J Alonzo
A transjugular venous access is an alternative approach for endovascular intervention in upper-extremity dialysis arteriovenous fistulae and grafts. The transjugular access is recommended for patients who have an unfavorable anatomy for the direct arm access approach. Ultrasound evaluation of the arteriovenous access is essential before intervention and includes evaluation of the inflow artery and outflow vein diameters, arteriovenous anastomosis, and the entire outflow vein, specifically looking into potential problem areas...

BACKGROUND: Brachial-cephalic arteriovenous fistulas (BCFs) are associated with high-flow volumes, leading to potential risks such as arm swelling, steal syndrome, pseudoaneurysm (due to a pressurized access), and cephalic arch stenosis. We hypothesized that a proximal radial-cephalic fistula (prRCF) configuration mitigates these risks because a lower flow state is created. Furthermore, we also hypothesized that despite these lower flows, patencies (primary, primary assisted, secondary) are sustained...

INTRODUCTION: Transposed basilic vein arteriovenous fistulas suffer from stenosis at their basilic angle of transposition (BAT). This lesion exhibits frequent recurrence after angioplasty. The primary goal of this study was to determine the effect of stent-graft placement on BAT lesion- and access-patency. The secondary goals were to determine the frequency of intervention pre- and post-stent placement and stent-associated stenosis. METHODS: Thirty-seven cases had stent-grafts placed at their BAT to manage stenosis...

Objectives The modern era of hemodialysis access surgery began with the publication in 1966 by Brescia et al. describing the use of a surgically created arteriovenous fistula. Since then, the number of patients on chronic hemodialysis and the number of publications dealing with hemodialysis access have steadily increased. We have chronicled the increase in publications in the medical literature dealing with hemodialysis access by evaluating the characteristics of the 50 most cited articles. Methods We queried the Science Citation Index from the years 1960-2014...

BACKGROUND: Patients starting dialysis often have substantial residual kidney function. Incremental hemodialysis provides a hemodialysis prescription that supplements patients' residual kidney function while maintaining total (residual + dialysis) urea clearance (standard Kt/Vurea) targets. We describe our experience with incremental hemodialysis in patients using NxStage System One for home hemodialysis. CASE PRESENTATION: From 2011 to 2015, we initiated 5 incident hemodialysis patients on an incremental home hemodialysis regimen...

PURPOSE: To report an investigation of a purely endovascular procedure to address access-induced hand ischemia in dialysis patients. CASE REPORT: Two dialysis patients presented with stage III steal syndrome consisting of severe pain and numbness in their fingers. Preoperative fistulograms distal to the anastomosis showed alternating antegrade and retrograde flow. Under ultrasound guidance, the fistula was accessed and a 4-F micropuncture sheath placed. An angled guidewire was then advanced proximally into the brachial artery...

Bleeding from dialysis vascular access (arteriovenous fistulas, arteriovenous grafts, and vascular catheters) is uncommon. Death from these bleeds is rare and likely to be under-reported, with incident rates of fewer than 1 episode for every 1,000 patient-years on dialysis, meaning that dialysis units may experience this catastrophic event only once a decade. There is an opportunity to learn from (and therefore prevent) these bleeding deaths. We reviewed all reported episodes of death due to vascular access bleeding in Australia and New Zealand over a 14-year period together with individual dialysis units' root cause analyses on each event...

BACKGROUND AND OBJECTIVES: Persons receiving outpatient hemodialysis are at risk for bloodstream and vascular access infections. The Centers for Disease Control and Prevention conducts surveillance for these infections through the National Healthcare Safety Network. We summarize 2014 data submitted to National Healthcare Safety Network Dialysis Event Surveillance. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Dialysis facilities report three types of dialysis events (bloodstream infections; intravenous antimicrobial starts; and pus, redness, or increased swelling at the hemodialysis vascular access site)...

OBJECTIVE: The durability of cryopreserved allograft has been previously demonstrated in the setting of infection. The objective of this study was to examine the safety, efficacy, patency, and cost per day of graft patency associated with using cryopreserved allograft (vein and artery) for hemodialysis access in patients with no autogenous tissue for native fistula creation and with arteriovenous graft infection or in patients at high risk for infection. METHODS: Patients implanted with cryopreserved allograft for hemodialysis access between January 2004 and January 2014 were reviewed using a standardized, multi-institutional database that evaluated demographic, comorbidity, procedural, and outcomes data...

BACKGROUND: The optimal timing of vascular access referral for patients with chronic kidney disease who may need hemodialysis (HD) is a pressing question in nephrology. Current referral policies have not been rigorously compared with respect to costs and benefits and do not consider patient-specific factors such as age. STUDY DESIGN: Monte Carlo simulation model. SETTING & POPULATION: Patients with chronic kidney disease, referred to a multidisciplinary kidney clinic in a universal health care system...

BACKGROUND: For patients waitlisted for a deceased-donor kidney, hospitalization is associated with a lower likelihood of transplantation and worse posttransplant outcomes. However, individual-, neighborhood-, and regional-level risk factors for hospitalization throughout the waitlist period and specific causes of hospitalization in this population are unknown. METHODS: We used United States Renal Data System Medicare-linked data on patients waitlisted between 2005 and 2013 with continuous enrollment in Medicare Parts A & B (n=53 810) to examine the association between annual hospitalization rate and a variety of demographic, clinical, and social factors...

COMPARATIVE STUDY
Shouwen Wang, Michele S Wang
OBJECTIVE: Arteriovenous fistulas and grafts may often be associated with localized complications related to aneurysms/pseudoaneurysms, buttonholes, or structural defects that require proper management to ensure continued access functionality for hemodialysis. Partial aneurysmectomy and repair (PAR) is a targeted surgical approach specifically designed for managing these complications. The basic concepts of PAR include resecting unhealthy or excessive tissue over an access, reconstructing the vascular access lumen using in situ vascular wall or tissue when possible, and closing overlying skin with healthy margins to promote reliable healing...
