1 Blood flow dynamics in patients with hemodialysis access-induced hand ischemia 
Roel H.D. Vaes, MD, Jan H. Tordoir, MD, PhD, Marc R. Scheltinga, MD, PhD  Journal of Vascular Surgery  Volume 58, Issue 2, Pages e1 (August 2013) DOI: /j.jvs Copyright © 2013 Society for Vascular Surgery Terms and Conditions

3 Fig 2 Correlation (r = 0.87; P = .01) between mean ulnar artery peak systolic velocity (PSV) and systolic index finger pressure (Pdig) of study patients (hemodialysis access-induced distal ischemia [HAIDI], n = 9; control [CONT], n = 10; data of one HAIDI patient was missing).

4 Fig 3 Correlation (r = 0.06; P = .81) between mean radial artery peak systolic velocity (PSV) and systolic index finger pressure (Pdig) (hemodialysis access-induced distal ischemia [HAIDI], n = 8, control [CONT] n = 10, data of two HAIDI patient were missing).

5 Fig 4 Static image of dynamic angiography showing a brachiocephalic (BC) fistula with inflow artery (brachial artery [A1]), ulnar (A2) and radial artery (A3), distended cephalic outflow vein (V) and arterial collaterals bypassing the anastomosis (C1-3). A steal phenomenon was observed in the proximal portion of the radial artery (S) reflecting proper collateral functioning. However, flow direction was antegrade in the remaining portion of the radial as well as in the ulnar artery.
