Is the Two-Stage Construction Approach Better for Maturation and Long-term Patency of the Transposed Brachiobasilic Arteriovenous Fistulas?

Abstract

The transposed brachiobasilic arteriovenous fistula is often constructed by employing a two-stage procedure for better maturation and long-term patency, but its validity on overall outcomes remains controversial. A single-center's experience is presented herein, comparing one- and two-stage approaches on 229 consecutive first-time arteriovenous access constructed in the upper arm with a loop configuration and an obtuse anastomosis angle that provide favorable flow dynamics. The one- and two-year patency rates were equivalent between the two approaches, but the fistula rate was greater and the maturation time was shorter with the one-stage procedure.
