  • The brachial-cephalic fistula is created by anastomosing the upper arm cephalic vein to the brachial artery in the antecubital fossa or just above the elbow. Because of the lateral and relatively superficial location of the cephalic vein, the brachial-cephalic fistula is easy to cannulate. It also provides a long length of straight vein from which to select cannulation sites. In patients with obesity or those in whom the cephalic vein is deeper than 5 to 6 mm from the skin, the brachial-cephalic fistula may require superficialization to make it possible to be cannulated. This more proximal acc…

  • The radial-cephalic AV fistula has a lower blood flow rate than the more proximal AV fistulas. Its use as the first access preserves the more proximal arm vessels for later access attempts. It is generally a comfortable means of dialysis, requires less frequent superficialization, and may dilate the more proximal veins to enable easier fistula creation in the future.

  • Although a variety of different anatomic types of AV fistula can be created, most AV fistulas fall within these basic types: ●Radial-cephalic, which is the radial artery and the cephalic vein at the wrist ●Forearm basilic, which is the radial or ulnar artery and the basilic vein at the wrist ●Brachial-cephalic, which is the brachial artery and the cephalic vein in the proximal forearm ●Brachial-basilic, which is the brachial artery and the basilic vein in the upper arm ●Lower extremity, which is the superficial femoral artery and the saphenous or femoral/popliteal vein in the thigh
