Background. Available evidence suggests a reduced mortality risk for patients treated with high-volume postdilution hemodiafiltration (HDF) when compared with hemodialysis (HD) patients. As the magnitude of the convection volume depends on treatment-related factors rather than patient-related characteristics, we prospectively investigated whether a high convection volume (defined as ≥22 L/session) is feasible in the majority of patients (>75%). Methods. A multicenter study was performed in adult prevalent dialysis patients...

OBJECTIVE: Current Kidney Disease Outcomes Quality Initiative guidelines do not incorporate age in determining autogenous arteriovenous hemodialysis access placement, and the optimal initial configuration in elderly patients remains controversial. We compared patency, maturation, survival, and complications between several age cohorts (<65 years, 65-79 years, >80 years) to determine whether protocols should be modified to account for advanced age. METHODS: All patients at two teaching hospitals undergoing a first autogenous arteriovenous access creation in either arm between 2007 and 2013 were retrospectively analyzed from a prospectively maintained database...

BACKGROUND: For people requiring hemodialysis, infectious mortality is independently associated with geographic distance from a nephrologist. We aimed to determine if differential management of catheter-related blood stream infections (CRBSIs) could explain poorer outcomes. METHODS: We prospectively collected data from adults initiating hemodialysis with a central venous catheter between 2005 and 2015 in Alberta, Canada. We collected indicators of CRBSI management (timely catheter removal, relapsing bacteremia); frequency of CRBSIs; hospitalizations; predictors of CRBSIs, and bacteremia...

Central venous catheters (CVCs) have an important role in the management of critically ill patients. In contrast to the immediate complications after CVC insertion, the late complications were difficult to be noticed without high suspicion despite their life-threatening outcome. We report a rare but fatal delayed vascular perforation occurring after 4 days of left-sided hemodialysis catheter insertion. A 74-year-old male with septic shock was treated with continuous renal replacement therapy (CRRT) and recovered smoothly during hospitalization...

Catheter-related bloodstream infections (CRBSI) are major complications for patients with life-threatening conditions requiring chronic vascular catheterization. The wide range of etiologic microbes and the ongoing development of resistance to antimicrobials with specific mechanisms of action make this an appropriate target for applying a nonspecific antimicrobial therapeutic. Taurolidine hydrolyzes into two antimicrobial moieties, formaldehyde and methylene glycol, which react with microbial surfaces. Neutrolin® (taurolidine, heparin, calcium citrate) was recently introduced in Germany as an antimicrobial catheter lock solution...

BACKGROUND: Acute kidney injury requiring renal replacement therapy (AKI-RRT) is associated with high morbidity, mortality and resource utilization. The type of vascular access placed for AKI-RRT is an important decision, for which there is a lack of evidence-based guidelines. METHODS: We conducted a prospective cohort study over a 16-month period with 154 patients initiated on AKI-RRT via either a non-tunneled dialysis catheter (NTDC) or a tunneled dialysis catheter (TDC) at an academic hospital...

Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma. A case of left brachiocephalic vein stenosis due to the insertion and function of a temporary right subclavian hemodialysis catheter is presented. The purpose of the manuscript is to emphasize that, with the introduction of a temporary subclavian hemodialysis catheter via the right subclavian vein apart from causing concurrent stenosis/infarction of the right subclavian and right brachiocephalic vein, it is also possible to cause stenosis of the left brachiocephalic vein (close to its contribution to the superior vena cava) although the catheter tip is placed in the correct anatomical position in the superior vena cava...

INTRODUCTION: The proximal cephalic vein that enters the axillary vein (cephalic arch) is a common site of stenosis in patients with upper extremity arteriovenous fistulas for hemodialysis (HD). In this study, we present the outcomes of a series of cephalic vein transposition, to determine its utility in the setting of refractory arch stenosis. METHODS: We conducted a retrospective review of patients undergoing cephalic vein transposition to manage refractory cephalic arch stenosis from January 1, 2008 to August 31, 2015...

INTRODUCTION: Citrate 4% is an alternative to heparin as catheter-locking solution in chronic hemodialysis patients. We compared catheter dysfunction episodes, dialysis adequacy, plasminogen-tissular activators use and costs according to catheter-locking solution in our centre. METHODS: Prospective, monocentric, cohort study (NephroCare Tassin-Charcot) on 49 prevalent patients in chronic hemodialysis. Two main groups were formed according to the prescription of catheter-locking solution at the beginning of the study (03/02/2016) and followed until 05/10/2016: heparin (n=26) and citrate (n=22)...

To investigate the status of vascular access in hemodialysis patients in our center.
 Methods: The general information of hemodialysis patients and types and complications of vascular access at Xiangya Hospital of Central South University from April 2015 to April 2016, were retrospectively analyzed.
 Results: Among 258 prevalent patients, 87.60% of them had arteriovenous fistula (AVF), while 12.40% showed tunneled cuffed catheter. Of the 61 incident patients, 80.33% of them initiated dialysis with a non-tunneled and non-cuffed catheter, 8...

The tunneled central venous catheter (CVC) plays an important role for hemodialysis patients, but CVC-related thrombosis in the central veins remain problematic. This study is the first try to numerically find out what hemodynamic parameters are predisposed to the initiation and formation of thrombus after CVC insertion. And the potential relationship between hemodynamic parameters and the incidence rates of thrombosis occurrence was explored. The results revealed that the CVC insertion led to a significant increase of hydraulic resistance, wide-ranging abnormally high wall shear stress (WSS), and a great loss of flow rotation in the vein...

BACKGROUND: Patients with end-stage renal disease (ESRD) frequently require urgent-start dialysis. Recent evidence suggests that peritoneal dialysis (PD) might be a feasible alternative to hemodialysis (HD) in these patients, including in older patients. METHODS: This retrospective study enrolled patients aged > 65 years with ESRD who underwent urgent dialysis without functional vascular access or PD catheter at a single center, from January 2011 to December 2014...

BACKGROUND/AIMS: Up to 50% patients requiring dialysis receive an urgent, unplanned start (UPS) to renal replacement therapy (RRT). Most of these are initiated with an intravenous catheter and commenced and maintained on hemodialysis (HD). Although peritoneal dialysis (PD) could be an equipotent initial modality for RRT, it is used less frequently as long-term RRT in UPS patients. This multicenter-study aimed to evaluate the impact of a structured, in-hospital education program and factors influencing PD rates, especially in UPS patients...

In the United States, the responsibilities and scope of practice of nephrology nurses and patient care technicians working in hemodialysis units vary from state to state. This occurs in relation to the care and management of central venous catheters (CVCs) used for hemodialysis. The aim of this article is to review the pros and cons of non-nursing staff performing the management and care of CVCs. The pros include decreasing nursing task time, allowing nurses to devote their time to other higher functioning roles, while the cons include lack of technician skill, education, and experience to perform CVC management and care...

Background/Aims: This study aims to demonstrate whether the association between initial vascular access and mortality among hemodialysis patients varies by age. Methods: We conducted a retrospective study that included 2,552 patients who started hemodialysis. Vascular access was divided into three categories: percutaneous catheter, tunneled cuffed catheter, and arteriovenous (AV) access. Results: Survival rates for patients who received a central venous catheter, such as percutaneous or tunneled cuffed catheter, aged 65 to 74 years and those ≥ 75 years were reduced, but not for those aged < 65 years (log-rank test; p < 0...

INTRODUCTION: End-stage renal disease (ESRD) is a major public health concern in Morocco with an incidence in constant progression according to MAGREDIAL "Morocco Dialysis Registry". Patients are often sent late to nephrologists, which is a source of complications recognized in several countries. For these reasons, we tried to evaluate, in our context, the prevalence and factors of this late referral (LR). METHODS: This is a retrospective study which included all patients initiating hemodialysis between January 2007 and December 2015...
