End-to-side versus side-to-side anastomosis with distal vein ligation for arteriovenous fistula creation.

Introduction: There is lack of compelling evidence about the best technique to carry out the anastomosis between the artery and the vein: end to side or side to side. This issue was addressed by very few randomized controlled studies. This topic has recently re-emerged with the advent of the endovascular fistula creation using the side-to-side technique.
