INTRODUCTION: Stenosis of an arteriovenous fistula or arteriovenous graft for dialysis is a common problem. Stenosis may lead to a number of problems including failure of the fistula. Treatment of stenosis is commonly with percutaneous angioplasty or surgical patch angioplasty with autologous vein or synthetic graft or patch. Here we report the use of bovine pericardial patch angioplasty as an alternative mode of patch angioplasty when percutaneous intervention has failed. METHODS: Patients with fistulae treated with bovine patch angioplasty between 2013 and 2016 were identified from a prospectively maintained renal access database (Cyberren® )...

Diabetic nephropathy is the most frequent cause of end-stage renal disease worldwide. Dialysis patients with diabetes mellitus (DM) have more complications and shorter survival duration than non-DM dialysis patients, requiring more clinical attention and difficult management. The registry committee of the Korean Society of Nephrology has collected data about dialysis therapy in Korea through an on-line registry program and analyzed the characteristics of patients. A survey of dialysis patients in 2016 showed that 50...

Patients receiving hemodialysis are vulnerable to infectious diseases due to their impaired immunity and high risk of exposure to pathogens. To protect patients, staff, and visitors from potential infections, each hemodialysis unit should establish and follow standard infection control and prevention measures. Therefore, clinical practice guidelines were developed by a working group of nephrologists and infection control specialists to provide evidence-based guidance for dialysis physicians and nurses, with the aim of preventing infection transmission and controlling infection sources in hemodialysis facilities...

BACKGROUND: Hemodialysis graft outflow stenosis is a significant complication occurring in hemodialysis patients with prosthetic grafts for vascular access. Balloon angioplasty remains the first-line endovascular treatment of this complication, although covered stent graft implantation after balloon angioplasty also appears to be an effective and promising treatment. The aim of this study was to evaluate the efficacy and durability of stent graft placement after balloon angioplasty in comparison to balloon angioplasty alone for the treatment of graft outflow stenosis in hemodialysis patients...

INTRODUCTION: Thrombosis is one of the most common complications of dialysis vascular access and is a significant source of morbidity and healthcare-associated costs. In this retrospective study, outcomes for surgical thrombectomy and thrombolysis after access thrombosis in patients with arteriovenous fistulas or prosthetic grafts (arteriovenous grafts) were analysed. METHODS: All patients with a primary episode of dialysis access thrombosis between 2005 and 2013 were included which yielded 131 patients with 149 episodes of access thrombosis (108 arteriovenous grafts; 41 arteriovenous fistulas)...

The majority of incidental haemodialysis patients are systematically treated at the rate of three sessions per week, regardless of their level of residual kidney function. Incremental haemodialysis is a therapeutic strategy adapted to the residual kidney function level of each patient, to offer patients only the "dialysis dose" needed to supplement their residual kidney function, while ensuring that they achieve the objective of total clearance (renal+per-HD) recommended (weekly Standard Kt/V urea>2...

Continuous arteriovenous hemofiltration (CAVH) was proposed in 1977 as an alternative treatment for acute renal failure in patients in whom peritoneal dialysis or hemodialysis was clinically or technically precluded. In the mid-1980s, this technique was extended to infants and children. CAVH presented important advantages in the areas of hemodynamic stability, control of circulating volume, and nutritional support. However, there were serious shortcomings such as the need for arterial cannulation and limited solute clearance...

OBJECTIVE: Cephalic arch stenosis (CAS) is an important and recurring problem arising in hemodialysis patients because of the requirement for repeated interventions to maintain patency. The aim of this study was to determine predictive factors for recurrence of CAS after successful angioplasty. METHODS: A retrospective, case-control study was conducted at two ambulatory vascular access (VA) centers. All patients with a dysfunctional VA referred for an angiographic procedure and with a documented CAS as evidenced during the endovascular intervention (EI) between January 1, 2013, and December 31, 2015, were enrolled; 15 patients in whom an efficacious intervention was not possible were excluded...

OBJECTIVE: Arteriovenous grafts (AVGs) remain reliable substitutes for permanent hemodialysis access in scenarios that preclude the placement of native arteriovenous fistulas (AVFs). The majority of AVGs are constructed of expanded polytetrafluoroethylene (ePTFE), which is relatively inexpensive and readily available, but synthetic AVGs have poor patency rates. On the other hand, biologic grafts confer an advantage by virtue of their inherent similarity to the native human vasculature...

Thrombosis is the most important access-related complication. Several declotting procedures have been suggested falling mainly into two categories; thrombolysis-dependent and thrombectomy-dependent. Areas covered: Seventeen studies after 2001 have been published on percutaneous treatment of thrombosed vascular access. Authors performed a systematic review of these studies together with a parametric meta-analysis of data available investigating clinical success, postintervention assisted primary patency (PAPP) and independent factors that could influence outcome measures...
