INTRODUCTION: Clinical information continues to be limited regarding changes in the temporal risk profile for readmissions during the initial postoperative year in vascular surgery patients. We set out to describe the associations between demographics, clinical outcomes, comorbidity indices, and hospital readmissions in a sample of patients undergoing common extremity revascularization or dialysis access (ERDA) procedures. We hypothesized that factors independently associated with readmission will evolve from "short-term" to "long-term" determinants at 30-, 180-, and 360-day postoperative cutoff points...

Heart failure necessitating left ventricular assist device (LVAD) support can lead to kidney failure requiring dialysis. Some of these patients may require long-term hemodialysis (HD). Optimal vascular access for a patient on long-term HD therapy with an LVAD remains a complex issue. The majority of LVADs are of the continuous-flow type, and it has been theorized that native arteriovenous fistula maturation may be impaired in a setting of decreased pulsatile arterial flow. We describe a case of successful creation and use of an arteriovenous fistula in an HD-dependent patient with a continuous-flow LVAD...

BACKGROUND: Dialysis in elderly patients (>80-years-old) carries a poor prognosis, but little is known about the most effective vascular access method in this age group. An arteriovenous fistula (AVF) is both time-consuming and initially expensive, requiring surgical insertion. A central venous catheter (CVC) is initially a cheaper alternative, but carries a higher risk of infection. We examined whether vascular access affected 1-year and 2-year mortality in elderly patients commencing haemodialysis...

Most babies with chronic renal failure are identified antenatally, and over half that are treated with peritoneal dialysis receive kidney transplants before school age. Most infants that develop acute renal failure have hypotension following cardiac surgery, or multiple organ failure. Sometimes the falls in glomerular filtration and urine output are physiological and reversible, and sometimes due to kidney injury, but (illogically) it is now common to define them all as having 'acute kidney injury'. Contrary to widespread opinion, careful interpretation of the plasma creatinine concentrations can provide sensitive evidence of early acute renal failure...

BACKGROUND: Satisfactory vascular access flow (Qa) of an arteriovenous fistula (AVF) is necessary for haemodialysis (HD) adequacy. The aim of the present study was to further our understanding of haemodynamic modifications of the cardiovascular system of HD patients associated with an AVF. The main objective was to calculate using real data in what way an AVF influences the load of the left ventricle (LLV). METHODS: All HD patients treated in our dialysis unit and bearing an AVF were enrolled into the present observational cross-sectional study...

As a consequence of the central role of the arteriovenous fistula for dialysis (AVF) in the clinical management of the dialysis patient the necessity to limit the puncture-related complications to extend as much as possible the life of the vascular access. Accordingly, the AVF needling technique has gained growing attention. Alongside the traditional rope ladder (RL) puncture method, the buttonhole technique (BH) is increasingly popular; this technique employs the same cannulation sites of AVF in every dialysis associated with the use of dull needles to minimize vessels damage...

Vascular access intervention therapy (VAIVT) has been positioned as the first choice of treatment for stenosis lesions frequently observed in arteriovenous fistula (AVF) for hemodialysis patients in Japan. Furthermore, increased blood flow can provide a stable dialysis. In contrast, it has been reported that excess blood flow of AVF causes high-output heart failure. Although VAIVT is used to increase blood flow of AVF, the impact of VAIVT on cardiac load has been rarely reported. We examined the factors associated with cardiac load in hemodialysis patients undergoing VAIVT by measuring levels of α human atrial natriuretic polypeptide (hANP) and brain natriuretic peptide (BNP) before and after VAIVT...

PURPOSE: We compared the patency and the suitability of arteriovenous fistula (AVF) created for vascular access by two approaches: (a) physical examination with preoperative vascular mapping and (b) physical examination alone. METHODS: We compared the patency and the suitability of AVF created in patients for dialysis. There were two cohorts of patients of 79 patients each: (a) patients with AVF created based on the combination of physical examination and preoperative vascular mapping (PE+VM) and (b) patients with AVF created based on physical examination (PE) alone...

AIM: To evaluate the parathyroid ultrasonography and define parameters that can predict poor response to treatment in patients with secondary hyperparathyroidism due to renal failure. METHODS: This cohort study evaluated 85 patients with chronic kidney disease stage V with parathyroid hormone levels above 800 pg/mL. All patients underwent ultrasonography of the parathyroids and the following parameters were analyzed: Demographic characteristics (etiology of chronic kidney disease, gender, age, dialysis vintage, vascular access, use of vitamin D), laboratory (calcium, phosphorus, parathyroid hormone, alkaline phosphatase, bone alkaline phosphatase), and the occurrence of bone changes, cardiovascular events and death...

The large prevalence of respiratory acid-base disorders overlapping metabolic acidosis in hemodialysis population should prompt nephrologists to deal with the partial pressure of carbon dioxide (pCO2) complying with the reduced bicarbonate concentration. What the most suitable formula to compute pCO2 is reviewed. Then, the neglected issue of CO2 content in the dialysis fluid is under the spotlight. In fact, a considerable amount of CO2 comes to patients' bloodstream every hemodialysis treatment and "acidosis by dialysate" may occur if lungs do not properly clear away this burden of CO2...

INTRODUCTION: The relationship between intradialytic ultrafiltration volume and vascular access (VA) patency remains unclear. Using data from the Japan Dialysis Outcomes and Practice Patterns Study, we analyzed whether large-volume ultrafiltration was associated with VA failure in hemodialysis patients. METHODS: We included 2736 patients for whom it was possible to evaluate VA patency and bodyweight change during dialysis. Patients were divided into three groups according to the tertile of intradialytic ultrafiltration by bodyweight: low, -9...

BACKGROUND: Native arteriovenous fistula (AVF) is the most appropriate type of vascular access for chronic dialysis. Its patency rates depend on vascular wall characteristics. Ketoacid analogues of essential amino acids (KA/EAA) are prescribed in end-stage renal disease (ESRD) pre-dialysis patients to lower toxic metabolic products generation and improve nutritional status. We hypothesized that very-low protein diet (VLPD) supplemented with KA/EAA may influence arterial wall stiffness and affect AVF maturation rates and duration in pre-dialysis ESRD patients...

BACKGROUND: In patients with failure of an initial arteriovenous fistula (AVF), a subsequent vascular access is needed before hemodialysis (HD) initiation. METHODS: To assess the optimal access strategy after a failed AVF, we linked data from the US Renal Data System with Medicare claims data identifying 21,436 patients ≥ 67 years old who started HD between January 1, 2005, and December 31, 2008, with an AVF placed as their first predialysis access. Of the 10,568 subjects whose AVF failed, 1,796 patients had an AVF placed as a second access predialysis (AVF2 group) and 399 patients had an arteriovenous graft placed as a second access predialysis (AVG2 group)...

INTRODUCTION: Aerobic bacterial infections often complicate vascular access in patients receiving haemodialysis, leading to Catheter-Related Blood Stream Infections (CRBSI). Various studies report Gram - positive bacteria, Staphylococcus aureus (S. aureus) in particular, as the most common aetiologic agent. Studies on microbiological analysis in this subset of population from India are very few. AIM: To examine clinical and bacteriological profiles of haemodialysis patients developing CRBSI, the antibiotic susceptibility of the bacteria isolated from these patients and determine nasal carriage of S...

Patients needing hemodialysis are advised to have arteriovenous fistulas rather than catheters because of significantly lower mortality rates. However, disparities in fistula placement raise the possibility that patient factors have a role in this apparent mortality benefit. We derived a cohort of 115,425 patients on incident hemodialysis ≥67 years old from the US Renal Data System with linked Medicare claims to identify the first predialysis vascular access placed. We compared mortality outcomes in patients initiating hemodialysis with a fistula placed first, a catheter after a fistula placed first failed, or a catheter placed first (n=90,517; reference group)...

BACKGROUND AND OBJECTIVES: Few studies have evaluated vascular access use after transition from peritoneal dialysis to hemodialysis. Our study characterizes vascular access use after switch to hemodialysis and its effect on patient mortality and evaluates whether a peritonitis event preceding the switch was associated with the timing of permanent vascular access placement and use. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The US Renal Data System data were used to evaluate the establishment of a permanent vascular access in 1165 incident Medicare-insured adult patients on dialysis who initiated peritoneal dialysis between July 1, 2010 and June 30, 2011 and switched to hemodialysis within 1 year...
