Cannulation Technique and Arteriovenous Fistula Survival in Older Adult Patients on Hemodialysis

Cannulation technique has the potential to impact arteriovenous fistula (AVF) function. The aim of this research was to determine the impact of cannulation technique on the length of the functioning AVFs in older adult patients on hemodialysis. The study included 110 participants with fistula thrombosis who had used area technique or rope ladder technique. Biochemical parameters, gender, demographic, and clinical variables were determined. Patients who used the area cannulation technique differed significantly from patients using the rope ladder technique with regard to duration of hemodialysis (p < 0.001), outcome of the AVF revision (p = 0.045), and positioning of the anastomosis (p = 0.013). The group that used the area cannulation technique had a longer duration of hemodialysis, proximal anastomoses, and more successful revisions of AVFs.
