Increased reintervention in radial-cephalic arteriovenous fistulas with anastomotic angles of less than 30 degrees

RC fistulas with anastomotic angles of <30° have reduced primary and secondary patency and increased numbers of reinterventions, suggesting that, if possible, surgeons should avoid an anastomotic angle of <30° when creating RC fistulas. Anastomotic angles of <90° or ≥90° may not play a role in outcome of BC fistulas.
