Use of the Dorsal Vein of the Hand for Arteriovenous Fistula Creation

A radiocephalic arteriovenous fistula (AVF) in the anatomical snuffbox is the most distal site of AVF in the upper limb. When the cephalic vein distal to the wrist is in poor condition or thrombosed, creating the typical radiocephalic AVF in the distal forearm just proximal to the wrist will likely be considered. However, we have adopted an operative technique for creating a transposed radial arteryedorsal metacarpal vein AVF (RDAVF) in the anatomical snuffbox when possible in such cases. RDAVF is AVF using the most peripheral autologous vein in the upper limb. To our knowledge, the creation of an RDAVF has not been previously reported. We herein describe the steps of the technique and report the successful treatment of a hemodialysis patient who developed occlusion of a radiocephalic AVF in the anatomical snuffbox.
