The relationship between aortic calcification on chest radiograph and neurocognitive impairment after coronary artery bypass grafting.

Transposition of brachiobasilic arteriovenous fistulas: One-stage or two-stage technique and factors affecting the early maturation.

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.
