Effect of Buttonhole Cannulation With a Polycarbonate Peg on In-Center Hemodialysis Fistula Outcomes: A Randomized Controlled Trial

In this study, AVF survival was significantly greater when using buttonhole cannulation. The buttonhole technique significantly decreased the need for access interventions and reduced existing aneurysm enlargement. Concerns of increased infection rates or prolonged bleeding times with the buttonhole technique were not seen in this study. The buttonhole technique should be considered the cannulation technique of choice for AVFs.
