Intraoperative duplex ultrasonography was used to assess the degree of venodilatation of the basilic and cephalic ... AVF, 2 arteriovenous grafts, 2 radiobasilic AVF, and 1 brachial vein AVF.

Autologous arteriovenous access is the key to long-term success with hemodialysis and is strongly supported by the National Kidney Foundation's Dialysis Outcomes Quality Initiative guidelines.
