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...

OBJECTIVE: The purpose of the study was to aggressively salvage acutely occluded arteriovenous fistulas (AVFs) using duplex imaging as the sole imaging modality for percutaneous transluminal angioplasty of acutely thrombosed AVF. METHODS: Over a period of 12 months, 14 patients with acute thrombosis of their AVFs underwent 18 procedures in a single center for AVF salvage. All 14 patients presented with chronic renal failure, and six were diabetic. All patients were treated under duplex guidance alone...

BACKGROUND: Shifting from a short-term catheter to a long-term one is done either by removing the old catheter and placing a new long-term one via fresh new puncture site, or by replacing the old catheter with a long-term one over a guidewire. AIM: We aimed to describe our technique in changing a temporary line to a long-term catheter (LTC) over a guidewire and to determine the incidence of line-related infections following this procedure. MATERIALS AND METHODS: A retrospective pilot study was conducted between 2005 and 2010 at the American University of Beirut Hospital...

INTRODUCTION: Hemodialysis catheter malfunction is problematic. We aimed to determine clinical, catheter, and hemodialysis variables that predict: (i) catheter malfunction requiring recombinant tissue-plasminogen activator (TPA) treatment and (ii) the success of TPA administration. METHODS: Clinical, catheter, and hemodialysis variables were collected from a cohort of 559 catheters (141,526 catheter days) in 175 hemodialysis patients (2008-2011). Time to, and predictors of, catheter malfunction were determined for all catheters and primary catheters only, analyzed by Cox-proportional hazard model, multi-variable logistic regression model, and mixed-effect logistic regression models...

BACKGROUND: International guidelines recommend to limit the long-term use of central-veinous catheters in patients undergoing hemodialysis, because they expose the patient to a higher infectious risk than the fistulas. However, for some patients with comorbidity, switching to a permanent vascular access is not possible. In such case, the catheter is used for a longer period. It seems therefore important to study the influence of a prolonged duration of catheterization on infectious complications...

Hemodialysis (HD) is the most common mode of renal replacement therapy for end-stage renal disease (ESRD) patients in India. However, the practice and pattern of dialysis in a hospital serving rural population is largely unknown. A prospective study of 127 ESRD patients initiated on HD between January 2013 and December 2014 was done. The study included 101 males and 26 females, with a mean age of 50.05 ± 13.80 years. Native kidney disease was unknown in 45.67% of patients as they presented very late in their disease course...

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: Cardiac disease is highly prevalent in hemodialysis (HD) patients. Decreased tissue perfusion, including cardiac, due to high ultrafiltration volumes (UFVs) is considered to be one of the drivers of cardiac dysfunction. While central venous oxygen saturation (ScvO 2 ) is frequently used as an indicator of cardiac output in non-uremic populations, the relationship of ScvO 2 and UFV in HD patients remains unclear. Our aim was to determine how intradialytic ScvO 2 changes associate with UFV...

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...

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)...

Catheter-related infections and dysfunction are the main catheter complications causing morbidity and mortality in hemodialysis patients. However, there are no consistent data for the choice of catheter lock solutions for tunneled hemodialysis lines. In this prospective, multicenter, randomized, controlled trial, two lock regimens using three commercial catheter lock solutions were compared in 106 hemodialysis patients with a newly inserted tunneled central catheter. In the taurolidine group, TauroLock™-Hep500 was used twice per week and TauroLock™-U25,000 once a week...

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: Peritoneal dialysis as a mode of renal replacement therapy still has not been embraced widely as an alternative to hemodialysis. Furthermore, there is marked variability in peritoneal dialysis catheter insertion techniques and perioperative management within the United States. After the publication of best-demonstrated practices for peritoneal dialysis catheter placement, the utilization of peritoneal dialysis has increased significantly at our institution. We detail the long-term success of peritoneal dialysis catheter placement after the adoption of best-demonstrated practices...

BACKGROUND: Arteriovenous grafts made of polyurethane (PU) have the advantage of early cannulation obviating the placement of a central vein catheter in patients with an acute need for long-term hemodialysis. The aim of the present study was to evaluate the safety, efficacy and complication rate of PU vascular grafts for dialysis access in patients in whom early cannulation was performed. METHODS: Between January 2007 and December 2015, 125 straight brachial-axillary grafts were placed in patients with an acute thrombosis of a previous arteriovenous access...

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...
