Figure 1. Cumulative access patency of AVFs that matured with or without prior interventions and AVGs that did or did not require intervention prior to successful cannulation.

Figure 1

Access patency was shorter for AVF with prior intervention than AVF without interventions (P < .0001). Access patency was shorter for AVG with prior interventions than AVG without intervention (P < .0001). Access patency was similar for AVF and AVG without prior interventions (P =.16). Cumulative access patency was worse for AVF with prior interventions than for AVG without prior interventions (P = .01).
