Snuff-box arteriovenous fistulas.

A total of 192 AV fistulas were created at the anatomical snuff-box. One hundred and eighty-two (94.8%) of them were patent and ready for use at the end of one month. This fistula has several advantages over the more commonly performed Brescia-Cimino radio cephalic fistula at the distal forearm. Snuff-box fistula is easier to perform, has a better patency rate, fewer wound complications and preserves proximal sites for fistula.
