1 Radial artery deviation and reimplantation inhibits venous juxta-anastomotic stenosis and increases primary patency of radial-cephalic fistulas for hemodialysis  Nirvana Sadaghianloo, MD, Serge Declemy, MD, Elixène Jean-Baptiste, MD, PhD, Pierre Haudebourg, MD, Christophe Robino, MD, Mohamed Shariful Islam, MD, Réda Hassen-Khodja, MD, Alan Dardik, MD, PhD  Journal of Vascular Surgery  Volume 64, Issue 3, Pages e1 (September 2016) DOI: /j.jvs Copyright © 2016 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Schematic view of the surgical techniques. Left, Traditional radial-cephalic construction (control group). Right, The radial artery deviation and reimplantation (RADAR) technique; only one aspect of the vein is dissected to perform the anastomosis, and the radial artery is deviated with its pedicle (artery and two veins).

4 Fig 3 Kaplan-Meier curves and Breslow analysis for comparison between the radial artery deviation and reimplantation (RADAR) group and the historical control group. A, Estimation of the overall survival (P = .90). B, Estimation of the primary patency (P < ). C, Estimation of the secondary patency (P = .0003). D, Estimation of the cumulative rate of reintervention in the juxta-anastomotic segment (P = .0002).

5 Fig 4 Evaluation of fistula maturation in radial artery deviation and reimplantation (RADAR) access. A, Venous diameter. B, Arterial diameter. C, Access flow. The blocks represent 95% confidence interval (CI). The bars represent minimal and maximal values. *P < compared with 3-week measurement (one-way analysis of variance and Bonferroni post hoc analysis). D, Representative color duplex ultrasound image of the outflow vein. Alternating colors show spiral flow in the RADAR fistulas.
