Radial artery-second dorsal metacarpal vein arteriovenous fistula in the first interdigital space for hemodialysis: Utilization of the most peripheral site and autologous vein in the upper limb - A case report.

Introduction: The creation of the first arteriovenous fistula (AVF) as far distally in the upper limb as possible is ideal. We developed a new operative technique for creating a radial artery-second dorsal metacarpal vein AVF in the first interdigital space. This technique involves the creation of the AVF using the most peripheral site and autologous vein in the upper limb.

Case Presentation: We herein describe the steps of this technique and its successful performance in a 71-year-old man with end-stage renal disease.

Discussion: This technique has several advantages including preserving many future vascular access options and providing a long segment of arterialized vein for cannulation.

Conclusion: We consider this technique to be a worthwhile option and recommend the use in patients with the proper vessels for the creation of the AVF.
