Angiography of chronic hemodialysis arteriovenous grafts

American Journal of Roentgenology, 1978
The arteriovenous graft has become an accepted vascular access route for chronic hemodialysis. Angiography plays in important role in the demonstration of graft abnormalities and in the management of graft malfunction. We describe the two basic techniques of graft angiography and classify graft abnormalities and factors associated with graft ...

Bovine graft arteriovenous fistula for hemodialysis

The American Journal of Surgery, 1974
Abstract Repeated failure of conventional methods for hemodialysis has prompted the use of bovine arterial grafts as conduits in arteriovenous fistulas. Complications encountered in the use of the graft have been infrequent and have been attributed to technical difficulties that arose in four of the first five patients operated on.

Angioplasty for arteriovenous grafts and fistulae

Seminars in Nephrology, 2002
The technique of percutaneous transluminal angioplasty (PTA) has become routinely used in the management of hemodialysis access dysfunction. It is used for the management of problems that affect both AVF and grafts. In the case of fistulae, it is used for treatment of early failure caused by juxta-anastomotic stenosis and late failure related to venous

Upper Arm Arteriovenous Grafts Are Superior Over Forearm Arteriovenous Grafts in Upper Extremity Dialysis Access

Annals of Vascular Surgery, 2020
In this study, we compared the outcomes of forearm arteriovenous grafts (AVGs) and upper arm AVGs in a large, prospectively collected data set, which represents real-world experience with upper extremity prosthetic dialysis access, to determine if there are clinically significant differences in the upper arm and forearm positions.We identified 2,063 ...

Prosthetic Arteriovenous Grafts for Hemodialysis

The Journal of Vascular Access, 2009
Introduction Prosthetic arteriovenous (AV) grafts are indicated in patients with failed AV fistula (AVF), exhausted superficial veins or unsuitable vessels. Increasing the proportion of prevalent hemodialysis (HD) patients using autogenous AVF should reduce the need for AV grafts and associated morbidity.

Infection of Arteriovenous Graft Fistulas

Annals of Internal Medicine, 1978
Excerpt To the editor: The recent article by Dobkin and associates (1) emphasizes that antibiotic treatment alone is often successful in the treatment of arteriovenous fistula infections.

Patency in Arteriovenous Grafts in Hemodialysis Patients

Vascular and Endovascular Surgery, 2013
Objective: It is difficult to maintain a working access for patients on hemodialysis. Despite current Dialysis Outcome Quality Initiatives recommendations of “Fistula First,” not everyone qualifies for a fistula, and those patients undergoing the alternative treatment, a graft, can experience graft failure. This

Rapid, arteriovenous graft failure due to intimal hyperplasia: a porcine, bilateral, carotid arteriovenous graft model

Journal of Surgical Research, 2003
The loss of patency constitutes the major complication of arteriovenous (AV) polytetrafluoroethylene hemodialysis grafts. In most cases, this graft failure is due to intimal hyperplasia at the venous outflow tract, including proliferation of vascular, smooth muscle cells and fibroblasts with deposition of extracellular matrix proteins.

Arteriovenous Loop Grafts for Free Tissue Transfer

Vascular and Endovascular Surgery, 2012
Arteriovenous (AV) loop grafts are a type of vascular conduit that can be used to support free tissue transfer. Wounds of various etiologies may require free tissue transfer, and the AV loop graft is a useful adjunct when adjacent blood supply is inadequate. Here we present 2 cases and review the technique and published literature.

Geometric Enhancements of an Arteriovenous Graft

ASME 2009 Summer Bioengineering Conference, Parts A and B, 2009
End Stage Renal Disease (ESRD) is the degeneration of kidney function to remove uremic toxins from the blood. Currently there are over 484,000 sufferers of ESRD in the United States, with this figure predicted to rise to over 800,000 by 2020 [1]. The total cost of care for patients with ESRD was estimated to exceed 1 billion dollars in the United ...
