INTRODUCTION: With improved life expectancy and quality of life, elderly patients constitute a progressively larger fraction of consumers utilising renal replacement therapy (RRT). Although substantial data exist for younger cohorts, minimal evidence exists for outcomes of arteriovenous fistula (AVF) and central catheters (CVC) placed in those patients over 80 years. We examined outcomes of primary AVF placement in this cohort to ascertain durability and benefits of AVF in the over 80-year-old population...

Peritoneal dialysis (PD) interruption requiring hemodialysis (HD) is not uncommon and its frequently abrupt nature prevents timely creation of permanent HD access and avoidance of central venous catheters (CVC). We retrospectively studied a cohort of 24 end-stage renal disease (ESRD) patients (mean age 50.7 years, 83.3% African-Americans, 58.3% females, time on dialysis interquartile range [IQR] 0 - 65 days) who had simultaneous PD catheter insertion and backup arteriovenous fistula (AVF) creation between January 1, 2012, and December 31, 2013...

Background Dialysis access-associated steal syndrome is a major complication of arteriovenous fistula creation whereby the low-resistance venous conduit shunts arterial inflow through the anastomosis, resulting in clinically significant distal artery insufficiency. Herein, we describe a case of severe steal phenomenon with gangrene of a digit following placement of an arteriovenous fistula that was treated with a novel, entirely endovascular technique. To our knowledge, this was the first totally endovascular approach to dialysis access-associated steal syndrome...

OBJECTIVE: This article describes the use of a transjugular venous access for interventions in upper extremity hemodialysis arteriovenous fistulas (AVFs) and grafts. This access is used in selected patients in whom direct puncture of the hemodialysis access is considered to be difficult or cumbersome. Technical success was achieved in 96.7% of patients. If an intervention is unsuccessful, the transjugular access offers the possibility of placement of a dialysis catheter for temporary or long-term hemodialysis...

Background: Vascular access for hemodialysis is best provided by an arteriovenous fistula (AVF). AVF fail primarily because of neointimal hyperplasia. Asymmetric dimethlyarginine (ADMA) is a naturally occurring analogue of L-arginine, which is elevated in renal failure and impairs endothelial cell function. ADMA inhibits nitric oxide synthetase, leading to impaired nitric oxide production and contributing to the development of neointimal hyperplasia. ADMA was measured at the time of AVF placement to evaluate associations with access failure...

Arteriovenous fistulae are the preferred choice of vascular access in hemodialysis patients, however complications such as stenosis can lead to access failure or recirculation, which reduces dialysis efficiency. This study utilized computational fluid dynamics on a patient specific radio-cephalic fistula under hemodialysis treatment to determine the dynamics of access recirculation and identify the presence of disturbed flow. Metrics of transverse wall shear stress and oscillatory shear index were used to characterize the disturbed flow acting on the blood vessel wall, whilst a power spectral density analysis was used to calculate the any turbulence within the access...

Native arteriovenous fistula (AVF) is the favorite access for hemodialysis (HD). The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) recommends its creation in most patients with renal failure. Unfortunately, intensive efforts to promote native AVF in patients with marginal vessels have increased the rate of primary fistula failure. A non-functioning fistula prompts the use of central venous catheter (CVC) that, unlike AVF, has been associated with an increased risk of morbidity and mortality among patients receiving HD...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...

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...

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 (AVFs) 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...

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...

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: Scalp arteriovenous fistulas (AVFs) are rare lesions that may occur spontaneously or secondary to head trauma. A standard treatment strategy for these lesions has not been established to date. We present 3 cases of successful treatment of scalp AVFs using a combination of Onyx-18 and coils via a transvenous approach. METHODS: The patient database at Huashan Hospital, Fudan University, Shanghai, China was reviewed, and patients with scalp AVFs treated with Onyx-18 and coils via a transvenous approach were identified for analysis...

BACKGROUND: Development of recalcitrant stenotic lesions of the cephalic arch is a significant cause of dysfunction of brachiocephalic access arteriovenous fistulas (AVFs). Endovascular and surgical therapy can be used to treat cephalic arch stenosis. The aim of this study was to evaluate the outcomes of endovascular and surgical interventions for cephalic arch stenosis. METHODS: A retrospective review of all patients during a 16-year period with a compromised but not occluded brachiocephalic AVF due to cephalic arch stenosis was undertaken...

BACKGROUND AND OBJECTIVES: The optimal type of initial permanent access for hemodialysis among the elderly is controversial. Duration of central venous catheter dependence, patient comorbidities, and life expectancy are important considerations in whether to place an arteriovenous fistula or graft. We used an observational study design to compare clinical outcomes in elderly patients who initiated hemodialysis with a central venous catheter and subsequently had an arteriovenous fistula or graft placed...

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...

This clinical report details the results of endovascular treatment of symptomatic superior vena cava syndrome due to central vein stenosis or obstruction (CVSO) by stent angioplasty in patients with dialysis-dependent end-stage renal disease. A 3-year retrospective review of two institutional registries identified 25 chronic hemodialysis patients (17 men, 8 women) affected by CVSO who received endovascular treatment. The majority of the patients (n = 19) presented with symptomatic arm, breast, and facial swelling; and 6 patients presented with dialysis-access dysfunction and venous-line hypertension...

Placement of autogenous arteriovenous fistula (AVF) is one of the basic needs in hemodialysis patients. Although many studies have investigated the complications of AVF placement, the complaints expressed by patients have not been studied in a long-term study. The purpose of this study was to evaluate the incidence of complaints after placement of autogenous AVF in patients undergoing chronic hemodialysis. This cohort study was conducted on patients with end-stage renal disease undergoing AVF placement who were referred to Imam Reza hospital in Mashhad, Iran, from January 2015 to June 2016...
