1 Flow reduction in high-flow arteriovenous access using intraoperative flow monitoring 
Juergen Zanow, MD, Karen Petzold, MD, Michael Petzold, MD, Ulf Krueger, MD, Hans Scholz, MD  Journal of Vascular Surgery  Volume 44, Issue 6, Pages (December 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Technique of flow reduction by spindle-like, continuous narrowing suture (A) and placement of a PTFE strip around the narrowed segment of the fistula vein (B). Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 Flow volume of different access types before and after flow reduction. A, autogenous radial-cephalic direct wrist access; B, autogenous brachial-cephalic upper arm direct; C, autogenous brachial-basilic upper arm transposition; D, autogenous brachial-cephalic-basilic upper arm direct access; E, prosthetic brachial-axillary access; F, prosthetic axillo-axillary upper arm loop access; G, prosthetic axillo-axillary chest loop access; H, prosthetic femorofemoral looped inguinal access. Results represent mean ± SD. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

4 Fig 3 Flow volume rate (Q) and distal arterial pressure (P) in a patient with distal ischemia (pain at rest) caused by a brachial-cephalic-basilic upper arm direct access before (A) and after (B) flow reduction.
