Preoperative radial artery volume flow is predictive of arteriovenous fistula outcomes

Objective Guidelines recommend the creation of a wrist radiocephalic arteriovenous fistula (RAVF) as initial hemodialysis vascular access. This study explored the potential of preoperative ultrasound vessel measurements to predict AVF failure to mature (FTM) in a cohort of patients with end-stage renal disease in Northern Ireland. Methods A retrospective analysis was performed of all patients who had preoperative ultrasound mapping of upper limb blood vessels carried out from August 2011 to December 2014 and whose AVF reached a functional outcome by March 2015. Results There were 152 patients (97% white) who had ultrasound mapping and an AVF functional outcome recorded; 80 (54%) had an upper arm AVF created, and 69 (46%) had a RAVF formed. Logistic regression revealed that female gender (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.12-5.55; P  = .025), minimum venous diameter (OR, 0.6; 95% CI, 0.39-0.95; P  = .029), and RAVF (OR, 0.4; 95% CI, 0.18-0.89; P  = .026) were associated with FTM. On subgroup analysis of the RAVF group, RAVFs with an arterial volume flow  P Conclusions In this cohort, a radial artery flow rate
