Table 2. Relative advantages of AVFs and AVGs.

How are AVGs better than AVFs?

  1. AVGs require fewer interventions prior to successful cannulation for dialysis.

  2. AVGs have a lower primary access failure rate.

  3. AVGs are associated with a shorter duration of catheter-dependence.

  4. AVGs are associated with a lower likelihood of catheter-related bacteremia prior to successful access cannulation.

How are AVFs better than AVGs?

  1. AVFs have longer cumulative patency than AVGs, if primary failures are ignored.

  2. AVFs require fewer interventions than AVGs to maintain long-term patency for dialysis.

  3. AVFs have fewer infections than AVGs (provided that buttonhole cannulation is avoided).
