Abstract
BACKGROUND: The upper-arm native arteriovenous fistula for hemodialysis (HD) vascular access is an important option in the long-term HD population. This single-center cohort study evaluated intra-access blood flow (Q AC) in 3 variants of newly created upper-arm fistulae. METHODS: Fifty-three patients with mature, working, upper-arm fistulae composed of brachial artery to cephalic vein (n = 27), brachial artery to basilic vein (n = 13), and brachial artery to median antecubital vein (n = 13) fistulae were included. Nine of 13 brachio-median antecubital fistulae were of the Gracz type and used the deep perforating vein. Q AC was measured by means of ultrasound velocity dilution during HD. In brachio-median antecubital fistulae, additional flow in the alternate draining vein was measured by means of duplex ultrasound, with 9 of 11 studied patients showing a patent alternate outflow, of whom 7 patients showed substantial flow (median, 0.7 L/min). RESULTS: Q AC in the HD-used primary vein in brachio-median antecubital fistulae (0.85 L/min) was significantly less than those of brachiocephalic and brachiobasilic fistulae (1.4 and 1.7 L/min, respectively). However, when the additional flow provided by the patent alternate vein in brachio-median antecubital fistulae was considered, flow rates provided by all 3 variants of fistulae appeared similar. The inverse correlation between alternate-vein and primary-vein flows (r = -0.70; P = 0.017) suggested there was competitive flow between the 2 venous outlets. There was no instance of access recirculation. CONCLUSION: Upper-arm fistulae, regardless of type, provide excellent blood flows and should be considered routinely if a wrist fistula is not feasible. The patent alternate vein in the brachio-median antecubital or Gracz fistula may continue to drain a substantial amount of blood.
