output: hi there are three main types of auf arteriovenous fistula the radiocephalic fistula is a forearm fistula created by anastomosing the side of a radial artery to the end of a cephalic vein it is also referred to as the brescia cimino fistula the brachiocephalic fistula is an upper arm fistula created by connecting the side of a brachial artery to the end of a cephalic vein or slightly central to the level of the elbow finally the brachial arterytotransposed basilica vein btb fistula is another upper arm fistula this fistula is created by anastomosing the side of a brachial artery to the end of a basilica vein that has been transposed laterally and elevated superficially to make it amenable to dialysis cannulation other sites could be leg also I advise you to discuss it with your doctor the patient requires dialysis for sure or you can put a central line and replace it every 15 to 20 days but av fistula is the best option
