PURPOSE: Autogenous arteriovenous fistulas are the preferred access for hemodialysis. Yet when created, fistulas often fail to mature, requiring surgical or radiologic interventions before their use. This pilot study measures the vascular wall elasticity and flow gradient using an open-source ultrasound software program designed to aid in assessing fistula maturation. METHODS: A total of seven end-stage renal disease patients were enrolled for our study after providing informed consent...

PURPOSE: The most preferable vascular access for patients with end-stage renal failure needing hemodialysis is native arteriovenous fistula (AVF) on account of its access longevity, patient morbidity, hospitalization costs, lower risks of infection and fewer incidence of thrombotic complications. Meanwhile, according to National Kidney Foundation (NKF)̸Dialysis Out-comes Quality Initiative (DOQI) guidelines, AVF is more used than before. However, a significant percentage of AVF fails to support dialysis therapy due to lack of adequate maturity...

Intravenous (IV) resuscitation of burn patients has greatly improved outcomes and become a cornerstone of modern burn care. However, the heavy fluids and vascular access required may not be feasible in austere environments, mass casualty, or delayed transport scenarios. Enteral resuscitation has been proposed for these situations; we sought to examine the effectiveness of this strategy on improving burn-induced kidney injury. Anesthetized Yorkshire swine sustaining 40% TBSA full-thickness contact burns were randomized to three groups (n = 6/group): fluid deprivation, ad libitum water access, or 70 mL/kg/d Oral Rehydration Salt solution (ORS)...

BACKGROUND: Elderly patients comprise the fastest growing population initiating dialysis in United States. The impact of poor functional status and pre-dialysis health status on clinical outcomes in elderly dialysis patients is not well studied. METHODS: We studied a retrospective cohort of 49,645 incident end stage renal disease patients that initiated dialysis between January 1, 2008 and December 31, 2008 from the United States Renal Data System with linked Medicare data covering at least 2 years prior to dialysis initiation...

Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®). METHODS: We describe the case of a 70-year-old patient who was admitted to the emergency room due continuous low back pain with 3 days of evolution...

INTRODUCTION: Renal replacement therapy in end-stage kidney disease relies on dialysis in low-income countries. This maintenance treatment needs a reliable vascular access and is done through central venous catheter or creation of A-V fistulas. Several types of A-V fistulas can be done but due to some individual conditions, those possibilities may be exhausted rapidly. CASE PRESENTATION: A 31 year old female was diagnosed with an end stage renal disease for which she was prescribed maintenance dialysis...

Liquid biopsies, as blood and urine, could offer an invaluable, easily accessible source of biomarkers, and evidences for elucidating the pathological processes. Only few studies integrated the proteomes driven by more than one biofluid. Furthermore, it is not clear which biofluid better mirrors the alterations triggered by disease. Venous infiltrating RCC(Renal Cell Carcinoma) could represent an advantageous model for exploring this aspect. Herein, we investigate how blood and urine "proteomically" reflect the changes occurring during RCC infiltration into renal vein(RV) by label-free nLC-ESI-MS/MS...

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...

The maintenance of vascular access patency for end-stage renal disease patients on hemodialysis is necessary for survival. Many nephrologists, nurse practitioners, and nurses have limited experience with the physical examination of the arteriovenous fistula. In this review, we define key terms used in the assessment of an arteriovenous fistula. We discuss the arteriovenous fistula physical exam, including details of inspection, palpation, and auscultation. Using these concepts, we review the abnormal findings that can assist practitioners in determining the location of a stenosis...

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...

INTRODUCTION: Simultaneous kidney and pancreas transplant is the preferred treatment option for end-stage renal disease due to type 1 diabetic nephropathy. Vascular complications are detrimental to graft survival and can lead to graft loss in the early postoperative phase of transplantation. Generally, duplex Doppler ultrasound is used for vascular patency monitoring and pancreatectomy followed by re-transplantation is required in the majority of cases. Recently, pancreatic graft salvage with non-operative management, including medical anticoagulation and endovascular thrombectomy, in the early postoperative period has been described with success...

Zaccaria Ricci, Stefano Romagnoli
Continuous renal replacement therapy (CRRT) is commonly applied in critically ill patients affected by severe acute kidney injury for solute and volume control and to optimize acid-base and electrolytes balance. Although CRRT represents a life-saving procedure for these patients, it is a representation of a non-physiologic artificial kidney and the potential benefits of the treatment could be hampered by clinical and technical side effects. Different parts of the CRRT system can be a source of technical complications...

Patrick M Honore, Herbert D Spapen
Continuous renal replacement therapy (CRRT) is an important and widely used adjuvant treatment in critically ill patients. However, any CRRT protocol can be adhered to only when the technique is correctly installed and functioning properly. Within this context, an appropriate vascular access and a safe and effective circuit anticoagulation method are key requisites. The right internal jugular (RIJ) vein is the preferred route for insertion with the tip of the catheter placed in the right atrium. Both femoral veins offer a valuable alternative access, but catheters must be longer to avoid recirculation and circuit blood flow is lower as compared with that of the RIJ approach...
