Secondary access survival after successful use is inferior if an intervention was required prior to successful use. Access patency was shorter for AVFs with prior intervention than for AVFs without interventions (P<0.001). Access patency was shorter for AVGs with prior interventions than AVGs without intervention (P<0.001). Access patency was similar for AVFs and AVGs without prior interventions (P=0.16). Access patency was worse for AVFs with prior interventions than for AVGs without prior interventions (P=0.01). Modified from reference 16.
