Background : Tapered grafts, which have a smaller diameter on the arterial side, have been increasingly used for arteriovenous fistulae formation. We compared the outcomes of 4–6-mm tapered and 6-mm straight forearm loop arteriovenous grafts.
Methods : Hundred and three patients receiving forearm loop arteriovenous grafts between March 2005 and March 2015 were retrospectively analyzed: Group A: 4–6-mm tapered grafts, n = 78; Group B: 6-mm straight grafts, n = 25). In each group, complications and patency rates after surgery were assessed.
Results : Clinical characteristics or laboratory results, except for cerebrovascular disease history (Group A: 7.7%; Group B: 28.0%; P = 0.014), were similar between the groups. Overall complication rates were significantly lower in Group A (15.4%, n = 12/78 vs. 36.0%, n = 9/25; P = 0.03), but no significant differences existed for individual complications. Kaplan–Meier survival analysis revealed no significant differences in 1-year, 3-year, and 5-year patency rates between Groups (61.8%, 44.9%, and 38.5%, vs. 62.7%, 41.1%, and 35.3%, respectively).
Conclusion : Complication rates were lower with 4–6-mm tapered grafts than 6-mm straight grafts, with similar patency rates. Therefore, 4–6-mm tapered grafts are safe, more useful alternatives to existing 6-mm straight grafts.
