Arteriovenous fistula is the preferred option for vascular access in hemodialysis patients. The aim of this study was to assess different follow-up methods for hemodialysis patients in our hemodialysis center in China. A cohort of 124 patients with stage 3 chronic kidney disease was recruited and double-blind randomly assigned into two groups. Patients in Group A received phone calls to schedule their next consultation a week in advance. Patients in Group B scheduled their next appointment at the end of each visit...

The cephalic arch is a common location of stenosis, especially in brachiocephalic fistulas. The cephalic arch has a number of anatomic variations. Cephalic arch stenoses are often resistant and have poor primary patency. Here we describe an unusual case of a hemodialysis patient with a single-conduit supraclavicular cephalic arch draining into the external jugular vein presenting with recurrent cephalic arch stenoses and external jugular vein stenosis. In our view, extrinsic compression by the clavicle may contribute to the high rate of recurrence, the lack of complete dilation of even high-pressure balloons, and a theoretically heightened risk of rupture when cutting balloons are used...

In this study, we present two cases of sudden deaths of people with end-stage kidney with arteriovenous fistulas for long-term hemodialysis treatment. This procedure is associated with a number of known complications. While stenosis, thrombosis, and infection are well known, lethal hemorrhage from arteriovenous fistula is much less commonly encountered. Inspection of the bodies at the scene of the death by a medical examiner suggested that the deaths were due to exsanguination. Autopsies revealed visible defects on the front wall of the arteriovenous fistulas...

Volume-clamp technology (e.g. Finometer) has become a popular method of collecting continuous, non-invasive, hemodynamic information during hemodialysis. There is minimal data validating the technique in this patient group. A gold standard cardiac output measurement can be obtained using ultrasound dilution in patients with arterio-venous fistulae. Continuous cardiac output was measured in 124 hemodialysis sessions in 27 patients using a volume-clamp device (Finometer PRO). Ultrasound dilution measurement was first taken at baseline (Transonic HD03), then used to calibrate the Finometer...

The growing proportion of individuals suffering from chronic kidney disease has considerable repercussions for both kidney specialists and primary care. Progressive and permanent renal failure is most frequently treated with hemodialysis. The efficiency of hemodialysis treatment relies on the functional status of vascular access. Determining the type of vascular access has prime significance for maximizing successful maturation of a fistula and avoiding surgical revision. Despite the frequency of arteriovenous fistula procedures, there are no consistent criteria applied before creation of arteriovenous fistulae...

INTRODUCTION: Arteriovenous fistulas (AVF) frequently fail to mature. Postoperative ultrasounds provide objective measurements to predict unassisted AVF use for hemodialysis (unassisted use) and guide interventions to salvage nonmaturing AVFs. The optimal ultrasound criteria to assess AVF maturation are uncertain. We analyzed data from a multicenter, randomized, controlled, clinical trial to compare 2 published ultrasound maturation criteria used to predict unassisted AVF use for hemodialysis...

A patient-centered quality improvement program implemented in one Virginia hemodialysis facility sought to determine if peer-to-peer (P2P) programs can assist patients on in-center hemodialysis with self-management and improve outcomes. Using a single-arm, repeatedmeasurement, quasi-experimental design, 46 patients participated in a four-month P2P intervention. Outcomes include knowledge, self-management behaviors, and psychosocial health indicators: self-efficacy, perceived social support, hemodialysis social support, and healthrelated quality of life (HRQoL)...

Left ventricular assist devices (LVADs) improve survival in patients with advanced heart failure. As LVAD use increases, so do the number of patients with LVADs who also have kidney disease. However, there are only sparse data on how best to care for these patients. This review provides an overview of LVAD principles and indications, including blood pressure assessment and criteria for receipt of both destination and bridge to transplantation LVADs. Following LVAD implantation, kidney function may improve in the short term, particularly if cardiorenal physiology was present; in the longer term, data remain limited...

A common complication of arteriovenous fistula for hemodialysis is development of conduit stenosis, which compromises function and can result in access thrombosis. Possible treatment options include open repair and endovascular therapy, with the latter preferred due to lower morbidity and similar outcomes. Recurrence of conduit stenosis is common and, based on the pathophysiology of this lesion, the application of drug-coated balloon angioplasty is attractive. In this report, the application of drug-eluting balloon angioplasty for dialysis access stenosis in 18 consecutive patients is detailed and primary patency rates of 82% at 1 year and 68% at 2 years were calculated...

BACKGROUND: The clinical consequences of starting chronic peritoneal dialysis (PD) after emergent dialysis via a temporary hemodialysis (HD) catheter has rarely been evaluated within a full spectrum of treated end-stage renal disease (ESRD). We investigated the longer-term outcomes of patients undergoing emergent-start PD in comparison with that of other practices of PD or HD in a prospective cohort of new-onset ESRD. METHODS: This was a 2-year prospective observational study...

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: Transradial access (TRA) is preferred for coronary angiography (CA) or percutaneous coronary intervention due to reduced access-related complications, and mortality especially for patients with ST elevation myocardial infarction. Radial artery occlusion (RAO) is a known complication of TRA, and precludes its use as a future access site, conduit for coronary artery bypass grafting or for hemodialysis fistula placement. Although a standard dose (SD) heparin of 5000 Units is used during TRA, the risks of RAO and hematoma compared to lower dose (LD) remain unclear...
