Vascular Remodeling of Arteriovenous Fistula

ASME 2009 Summer Bioengineering Conference, Parts A and B, 2009
Arteriovenous (AV) fistula failure is a major clinical problem for the 350,000 patients currently on hemodialysis in the United States. The reasons for this failure are mainly attributed to venous stenosis due to neointimal hyperplasia together with a possible failure of vascular dilatation [1].

Vascular Access for Hemodialysis: Arteriovenous Fistula

Therapeutic Apheresis and Dialysis, 2005
Abstract:  The long‐term survival and quality of life of patients on hemodialysis (HD) is dependant on the adequacy of dialysis via an appropriately placed vascular access. The optimal vascular access is unquestionably the autologous arteriovenous fistula (AVF), with the most common method being the conventional radio‐cephalic fistula at the wrist ...

Hemodialysis fistula stenosis caused by extrinsic vascular compression: The May–Thurner of fistulas

The Journal of Vascular Access, 2020
Significant venous outflow stenosis of a forearm arteriovenous fistulae caused by an extrinsic vascular compression is a very rare entity (no reported cases in the literature). We report a case of high venous pressures during dialysis, secondary to an extrinsic compression of the underlying brachial artery that was diagnosed with Doppler ultrasound ...

Analysis of the vascular sounds of the arteriovenous fistula's anastomosis

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
In this paper, the vascular sounds of the arteriovenous fistula at the anastomosis and five centimeters downstream the anastomosis were analyzed. The analysis of the sounds was based on features extracted from the power spectral density (PSD) and wavelet decomposition.

The Role of Intrarenal Vascular Reconstruction for Arteriovenous Fistula

Journal of Urology, 1981
Recent reports on the use of embolization to treat intrarenal arteriovenous fistula have suggested that there is little need for surgical reconstruction. We report the successful use of intrarenal vascular reconstruction in a patient who presented with a large intrarenal arteriovenous fistula and hypertension to emphasize the fact that there still are ...

Vascular Access: Fistulae and Grafts

2014
Registry data suggests that approximately 20 % of patients present to renal services with dialysis-dependent renal failure without the opportunity to create timely native AV access. Many studies have drawn attention to the potentially serious complications associated with central venous dialysis catheters (CVC) [1]. These include the risk of thrombosis

Prosthetic arteriovenous fistula for vascular access in hemodialysis

The American Journal of Surgery, 1976
Vascular access through subcutaneous prosthetic arteriovenous fistulas was studied in eighteen dogs. Dacron velour and woven Dacron grafts (6 mm diameter) were constructed across the lower abdomen between the common femoral artery and the opposite common femoral vein.

Percutaneous Embolization of Vascular Fistulas Using Coils or Amplatzer Vascular Plugs

Revista Española de Cardiología (English Edition), 2009
A great variety of different types of vascular fistula are referred to cardiac catheterization laboratories for diagnosis and percutaneous occlusion. In addition, a wide range of devices is available for treating them percutaneously. The objectives of this study were to assess the usefulness and difficulty of treating vascular fistulas percutaneously ...

Vascularization of the arteriovenous fistula wall and association with maturation outcomes

The Journal of Vascular Access, 2019
Background and objectives: The venous vasa vasorum is the mesh of microvessels that provide oxygen and nutrients to the walls of large veins. Whether changes to the vasa vasorum have any effects on human arteriovenous fistula outcomes remains undetermined.

Use of Early Scanning in Fistula Formation for Vascular Access

The Journal of Vascular Access, 2010
Purpose To determine the feasibility and role of early scanning in the assessment of arteriovenous fistulae fashioned for vascular access. Methods Retrospective case note analysis of 98 patients who underwent early scanning (between 7 and 28 days) of their fistula as well as routine scanning at 6 weeks over a 2–year period.
