Evaluation of the Radial Artery Deviation And Reimplantation Technique for Primary Hemodialysis Access Creation
Sponsor: Centre Hospitalier Universitaire de Nice
Summary
The Radial Artery Deviation And Reimplantation (RADAR) technique is a new approach for the construction of hemodialysis arteriovenous fistula. In this technique, the radial artery pedicle is deviated towards the minimally dissected cephalic vein at the wrist. The aim of this study is to compare the safety and efficacy of this technique with the traditional end-cephalic to side-radial arteriovenous fistula, currently used as a first line vascular access in hemodialysis patients. The hypothesis is that the minimal dissection concept used in the RADAR inhibits venous juxta-anastomotic neointimal hyperplasia and stenosis, and lead to higher rates of maturation and patency.

Conditions
Interventions
End-cephalic vein to side-radial artery fistula creation
* Circumferential dissection of the cephalic vein (4-5cm long) * Longitudinal arteriotomy (\~10mm) * End-vein to side-artery anastomosis using 7-0 polypropylene continuous suture
RADAR fistula creation
* Dissection of the anterior-medial aspect of the cephalic vein (\~15mm) without grasping or clamping the venous wall * Circumferential dissection of the radial artery pedicle (5cm long) and ligation of collaterals with surgical microclips * Ligation and section of the radial artery (distal) * Longitudinal venotomy (\~10mm) * End-artery to side-vein anastomosis using 7-0 polypropylene continuous suture
