Impaired Hyperemic Response Is Predictive of Early Access Failure

Creating a Fistula That Works: Is It an Art or Is It Science?

“…In successful operations he observed that the veins were able to dilate in response to proximal compression by approximately 60%; in contrast, venous dilatation of 15% or less was associated with eventual failure. Comparable results have been reported by Wall et al [5] , Parmley et al [6] , Mendes et al [7] and others -although in a few publications the authors failed to encounter any signifi cant benefi t from Duplex ultrasound [8] .This is where the work of Ernandez et al [2] in this issue of Nephron Clinical Practice sets in. In 119 patients undergoing operations to create native fi stulae at the level of the forearm or of the upper arm, their surgical team used standard procedures -physical examination and Duplex ultrasound -in preparing the operation.…”

Factors affecting the patency of arteriovenous fistulas for dialysis access

“…31,32 The only other report of AVF patency and change in PSV after fist clenching showed an increase in AVF adequacy for dialysis only in women. 33…”

Current tools for prediction of arteriovenous fistula outcomes

“…[ 25 ] who found no difference in AVF outcomes, except in functional patency of AVFs in women and Wall et al . [ 26 ] who found no difference in primary functional AVF patency but a significant difference in secondary AVF patency following surgical revision. These studies do not lend themselves to direct comparison but do suggest that the ability of the artery to dilate plays a significant functional role in AVF maturation.…”
