External dilator-assisted banding for high-flow hemodialysis arteriovenous fistula

Arteriovenous Fistula Recirculation in Hemodialysis

Recently, with great interest we read the review article by Zeraati et al. entitled “A review article: access recirculation among end stage renal disease patients undergoing maintenance hemodialysis” in your most valuable journal (1). The author summarized some of observations about causes and clinical significance of arteriovenous (AV) fistula recirculation, techniques for accurate assessment ...

Saphenofemoral arteriovenous fistula as hemodialysis access

BACKGROUND An upper limb arteriovenous (AV) fistula is the access of choice for haemodialysis (HD). There have been few reports of saphenofemoral AV fistulas (SFAVF) over the last 10-20 years because of previous suggestions of poor patencies and needling difficulties. Here, we describe our clinical experience with SFAVF. METHODS SFAVFs were evaluated using the following variables: immediate r...

Numerical investigations of the unsteady blood flow in the end-to-side arteriovenous fistula for hemodialysis.

PURPOSE The aim of this study was to investigate the blood flow in the end-to-side arteriovenous (a-v) fistula, taking into account its pulsating nature and the patient-specific geometry of blood vessels. Computational Fluid Dynamics (CFD) methods were used for this analysis. METHODS DICOM images of the fistula, obtained from the angio-computed tomography, were a source of the data applied to...

Brachiocephalic Arteriovenous Fistula for Hemodialysis through the Median Antecubital Vein

In patients unsuitable for radiocephalic fistula creation, the next option is brachiocephalic fistula. In such patients, we exploited the venous interconnections in the cubital fossa for median cubital vein-Brachiocephalic arteriovenous fistula (AVF) creation. In this article, we describe our experience in the creation of such technical variant of the brachiocephalic fistula AVF, its success an...
