We Refuse to Give up on Nonmaturing Fistulas.

The nonmaturing arteriovenous fistula (AVF) is a major problem and can lead to significant patient morbidity and mortality because the patient is exposed to the risk of dialysis with a central venous catheter (CVC). Access planning should include a strategy to decrease the incidence of AVF nonmaturation. All newly created AVFs should be evaluated for maturation at 4-6 weeks. If it is judged to not be usable at that time, it should be evaluated for salvage. However, if multiple procedures over a prolonged period of time are necessary for salvage, the decreasing chances of long-term success with the increasing risks of CVC-based dialysis must be considered. Giving up on the nonmaturing AVF may be in the best interest of the patient.
