Surgery of Arteriovenous Interposition Grafts
European Surgery, 2003BACKGROUND: The history of vascular access surgery is marked by two milestones: firstly the invention of the subcutaneous arteriovenous fistula and secondly the introduction of an artificial interposition graft. The latter option has contributed to markedly increasing the number of patients on dialysis and also to extending their life expectancy, as ...

Arteriovenous Graft-Arteriovenous Fistula Conversion (Secondary Arteriovenous Fistula Creation)
2017Arteriovenous hemodialysis catheters have lower rates of primary and secondary patency than autologous arteriovenous fistulas in most patients. While emphasis has been placed on de novo construction of arteriovenous fistulae, grafts are still placed for primary access in a large population of end-stage renal disease placements.

The Journal of Vascular Access, 2019
Introduction: A functioning long-term vascular access is required for haemodialysis therapy; however, establishing this can be challenging in the setting of advanced age and vessels damaged by diabetes. Complications include the inability to insert two needles for the treatment resulting in miscannulation trauma

Experimental Models of Arteriovenous Grafting
2001Venous tissue remains the most widely used arterial conduit for the treatment of occlusive coronary and peripheral vascular disease. However, neointima formation and the accelerated rate of atherosclerosis in these grafts leads to an unacceptably high failure rate, necessitating reoperation or revision in 50% of patients within 10 yr.

Arteriovenous Graft Life in Chronic Hemodialysis
Archives of Surgery, 1988As long-term hemodialysis has become well accepted over the last 25 years, so has the need for more exacting and updated techniques for arteriovenous graft construction. The death rate for patients with chronic renal failure undergoing biweekly or triweekly hemodialysis was once generally 10% per year.

Exotic Arteriovenous Graft Creation
2017Vascular access in long-term hemodialysis patients is an evolving and increasingly complex situation facing vascular access surgeons. Central stenosis from repeated and long-term catheter use is the primary complication necessitating new techniques and technology to provide reliable and durable long-term internal access for these patients.

A new method of creating an arteriovenous graft access
The American Journal of Surgery, 1996Since the initial description of the radial arteriovenous (AV) shunt, hemodialysis has played a primary role in the survival of patients with chronic renal failure. However, it is not unusual to be confronted with patients on chronic hemodialysis who have exhausted all superficial venous access sites. We describe a technique using the deep veins of the

Arteriovenous Graft Inflow Stenosis
2017Arteriovenous accesses, both the grafts (AVG) and fistulae (AVF), require patency of inflow and outflow for performance of adequate dialysis. The presence of significant stenosis of the inflow reduces access flow, jeopardizes provision of adequate dialysis, and leads to eventual failure of AV access.

Early Cannulation of the Flixene™ Arteriovenous Graft
The Journal of Vascular Access, 2016Purpose The aim of this review was to search for evidence of the efficiency of early cannulation of the Flixene™ (Maquet-Atrium Medical, Hudson, NH, USA) arteriovenous graft (AVG) in the current literature and to assess its patency and complication rates.

Arteriovenous Graft with Traumatic Fistula
2017This case is an example of a traumatic fistula occurring in an arteriovenous graft (AVG). The mechanism by which this occurs is the cannulation needle passing through the wall of the access (in this case the pseudoaneurysm) and entering a vein. When this occurs if the resistance to flow in the graft is higher than that in the perforated vein, a fistula
