Extending Outflow Brachial Vein Tength for Transposition Arteriovenous Fistulas

Abstract

Creating a longer transposition AVF venous outflow segment using parallel and overlapping vein segments with an end-to-end anastomosis gained the adequate length needed for successful T-AVFs in these four patients.

Proximal Ulnar Artery Arteriovenous Fistula Inflow is an Uncommon but useful Vascular access Option

“…Brachial vein transpositions offer reliable vascular access; however, they involve more complex operations, careful planning, and are best performed in staged procedures (13, 14). When the maturing brachial outflow vein is incomplete, establishing a functional transposed outflow vessel is much more complicated (15). Evaluation of both arms with ultrasound by the operating surgeon is the key element for identifying the largest intact brachial vein for eventual transposition (1, 16).…”
