INTRODUCTION: The buttonhole (BH) puncture technique for arteriovenous fistulas is an alternative to the classical staggered puncture. PURPOSE: We present 3years' results incorporating the BH puncture technique for arteriovenous fistulas in our dialysis unit. MATERIAL AND METHODS: Twenty-two patients were started on BH technique, 15 men and 7 women (mean age: 62 years; SD: 12), with time spent on dialysis when starting the BH technique of 34 months (SD: 34, median: 27, range: 3-136)...

BACKGROUND: The possibility of coronary steal through an arteriovenous fistula (AVF) in hemodialysis (HD) patients with coronary artery bypass grafts (CABGs) using an ipsilateral internal thoracic artery (ITA) has been suggested. In order to define the significance of such a possibility, we analyzed cardiac events and mortality risk in patients in relation to AVF flow. METHODS: A retrospective cohort study was performed on prevalent HD patients from a single center...

REVIEW
Blake Lerner, Sean Desrochers, Navdeep Tangri
Chronic kidney disease (CKD) currently affects 20 million Americans and is associated with increased morbidity and mortality. Resource-efficient and appropriate treatment of CKD benefits the patient and provides improved resource allocation for the health care system. Prediction models can be useful in efficiently allocating resources, and currently are being used at the bedside for several important clinical decisions. There is a paucity of prediction models in use in nephrology, but one such model, the Kidney Failure Risk Equation, uses routinely collected laboratory values and can inform clinical decisions related to the following: (1) triage of nephrology referrals, (2) evaluating the need for more intensive interdisciplinary clinic care, (3) determining the timing of modality education, and (4) dialysis access planning...

The population of patients with end-stage renal disease (ESRD) in the United States is progressively increasing, with hemodialysis (HD) as the major mode of renal replacement therapy. National guidelines recommend increasing the use of arteriovenous fistulae (AVF) in both incident and prevalent hemodialysis patients. Pre-operative vascular mapping prior to the surgical creation of an AVF is now considered standard of care and may be helpful in achieving these goals. This manuscript focuses on the advantages and limitations of the various imaging techniques currently available for vessel mapping including physical examination, ultrasonography, angiography (iodinated contrast vs...

Angiography of the dialysis access is an important procedure in dealing with dialysis arteriovenous access (AVA) dysfunction. It is an integral part and the initiating procedure for all the interventional procedures performed for the management and salvage of dialysis AVA. The performance of this procedure and normal dialysis access-related anatomy including anatomical variants are discussed. In addition, pathology commonly encountered in association with the anatomy is reviewed.

PURPOSE: A native vessel is preferable to an artificial graft for dialysis access. Duplex ultrasound (DUS) is noninvasive, cost-effective modality to evaluate the vessels for dialysis. The purpose of this study was to compare the rates of utilization of native vessels after preoperative imaging with DUS and contrast venography (CV). MATERIALS AND METHODS: A retrospective review was performed on patients who received an arteriovenous fistula (AVF) or arteriovenous graft (AVG) between June 2006 and July 2010...

BACKGROUND: In incident hemodialysis (HD) patients the use of catheters is associated with a worse prognosis when compared to those with an arteriovenous fistula (AVF), but the role of vascular access (VA) type in the morbidity and mortality of patients returning to HD with a failing renal allograft is unknown. We aimed to determine the associations between the type of vascular access and mortality in this population. METHODS: This was a retrospective observational cohort study of 138 patients who initiated dialysis after kidney transplant failure between 1995 and 2014...

Primary use of the autogenous arteriovenous access is recommended by the National Kidney Foundation-Dialysis Outcomes Quality Initiative guidelines. In spite of troublesome comorbidities associated with basilic vein transposition (BVT), it is still the most preferred technique when autologous veins are not suitable to construct radio-cephalic fistula (RCF) and brachiocephalic fistula (BCF), arteriovenous fistula (AVF). The present study highlights our experience with BVT, with small incision technique, over a period of two years with excellent outcome...

BACKGROUND: Fistulas are the preferred permanent hemodialysis vascular access, but a significant obstacle to increasing their prevalence is the fistula's high "failure to mature" (FTM) rate. This study aimed to identify postoperative clinical characteristics that are predictive of fistula FTM. MATERIALS AND METHODS: This descriptive cross-sectional study was performed on 80 end-stage renal disease patients who referred to Al Zahra Hospital, Isfahan, for brachiocephalic fistula placement...

PURPOSE: Dialysis access failure is a major cause of morbidity in patients with end-stage renal disease. The Fistula First Breakthrough Initiative (FFBI) dictates arteriovenous fistulae (AVFs) should be preferred over arteriovenous grafts (AVGs) as first line for surgically placed accesses. The purpose of this study was to compare patency rates of surgical dialysis accesses in our mature, urban population after the FFBI. METHODS: Current dialysis patients with accesses placed between 2006 and 2011 were included...

Aims: Short-term studies have reported left ventricular (LV) dilatation following surgical creation of arteriovenous fistulas (AVF) or arteriovenous grafts (AVGs), but chronic cardiac structural and functional changes have not been examined or related to clinical outcomes following AVF/AVG. We sought to characterize the long-term changes in cardiac structure and function in patients undergoing shunt creation for haemodialysis. Methods and results: A retrospective analysis was performed of patients undergoing echocardiography before and after surgical AVF/AVG creation for the initiation of haemodialysis...

BACKGROUND: Most guidelines recommend the creation of arteriovenous fistula (AVF) in patients with chronic kidney disease (CKD) stage 4. However, an increasing number of studies suggest that early AVF creation leads to high rates of AVF failure and death before dialysis commencement. Only the Japanese guideline recommends AVF creation at CKD stage 5; however, no data are available regarding access-related outcomes at this stage. METHOD: This was a multicenter cohort study involving Japanese CKD stage 5 patients who underwent preemptive AVF creation from 2009 to 2013...

OBJECTIVE: To study the effect of early cannulation of arteriovenous fistulas (AVF) on early AVF failure. METHODS: Analysis of two databases of access operations and dialysis sessions from 1/12/2002 till 1/4/2015. Follow-up until 1/4/2016. Functional dialysis use defined as six consecutive cannulations of the AVF with two needles. Early cannulation defined as needling of the AVF within 30 days of creation. Early failure was defined as abandonment for new form of access within 90 days of first cannulation...

Many guidelines recommend that end-stage renal disease (ESRD) patients should have a permanent vascular access, preferably an autologous arteriovenous fistula (AVF), at the start of renal replacement therapy. Nevertheless, a large proportion of patients still start hemodialysis with a central venous catheter (CVC). On the other hand, there are increasing numbers of patients in whom an AVF has been created, but who never actually end up on dialysis, as well as a substantial number of patients in whom creation of a vascular access has been attempted unsuccessfully...

Autogenous fistulas and in particular radiocephalic fistulas are recommended as the first vascular access for hemodialysis. Unfortunately, the rates of early failure and non-maturation are very high. For more than a decade, brachial plexus block has been proposed as the anesthesia of choice for fistula creation due to its beneficial sympathectomy-like effect, causing vasodilation and attenuation of spasm. Until recently, there was not a single randomized clinical study supporting this proposition. Because performing regional anesthesia is time-consuming and requires expertise, many surgeons prefer local or general anesthesia for vascular access surgery...

Impaired fistula maturation is associated with puncture-related complications, insufficient dialysis and potential permanent access failure. Non-maturation is frequently initiated by stenotic vascular access vessels comprising the outflow veins, the arteriovenous anastomosis and infrequently the inflow artery. Further findings in maturation protraction are central venous stenoses or accessory outflow veins. Depending on the underlying pathology, several endovascular approaches to boost fistula maturation are possible...
