Abstract
The brachiobasilic transposition (BBT) arteriovenous fistula (AVF) is a valuable option especially for dialysis patients with previously failed vascular access. We aim to report factors affecting the maturation of BBT-AVF created with either one-stage or two-stage technique. BBT-AVF procedures between January 2015 and May 2019 by a dedicated vascular access team were investigated retrospectively. A total of 122 patients (63 males, 59 females), with 6 to 12 weeks of follow-up after the BBT-AVF procedure were included in the study. Patients of one-stage and two-stage techniques were compared for maturation rates. Patients with successful and failed maturation were compared for baseline characteristics and anatomic factors. Of 122 BBT-AVF procedures, 54 were created with the one-stage and 68 were created with the two-stage technique. The mean age of the patients was 58.2 ± 13.8, the mean brachial artery and basilic vein diameters were 3.91 ± 1.02 mm, and 3.39 ± 1.16 mm. Of 122 included patients, 88 (72.1%) had mature AVFs at follow-up. The AVF maturation rates were similar between the one- and two-stage groups (70.4% vs 73.5%; P=.699). Lower age (62.8 ± 12.5 vs 56.5 ± 13.9; P=.023) and greater brachial artery diameter (3.09 ± 0.84 mm vs 4.23 ± 1.76 mm; P < .048) were the only factors affecting the AVF maturation in univariate analysis. Gender, extremity side, diabetes mellitus, hypertension, and targeted vein diameter were not found to affect the AVF maturation (P=.301, P=.084, P=.134, P=.858, P=.127). Target artery diameter (P=.049) was the only significant factor affecting BBT-AVF maturation in multivariate analysis. One-stage and two-stage BBT-AVFs are similar in terms of maturation rates. Targeted artery diameter was the only factor important in BBT-AVF maturation in our study group. The two-stage technique can be preferred considering smaller incision size and lower complication rate in patients with suitable anatomy.
