Who is a candidate for an AVF?
There are very few instances where a fistula is not indicated. Nowadays, in the majority (including those with diabetes or who are “older”) of patients a “mapping” study of the blood vessels in the arm is conducted, which will help select the best veins for a fistula and decrease the chance for an unsuccessful surgery. Be persistent, if the mapping study was not done, asking for a second opinion is quite reasonable.
