Clinical Outcomes of Arteriovenous Graft in End-Stage Renal Disease Patients with an Unsuitable Cephalic Vein for Hemodialysis Access

Abstract

Background: As the population of patients with end-stage renal disease has grown older, the proportion of patients with poorly preserved vasculature has concomitantly in-creased. Thus, arteriovenous grafts (AVG) have been used more frequently to access blood vessels for hemodialysis. Despite this increasing demand, studies of AVG are limited. In this study, we examined the surgical outcomes of upper-limb AVG creation.Methods: Among the arteriovenous fistula formation procedures performed between January 2014 and March 2019 at Dankook University Hospital, 42 cases involved AVG cre-ation. We compared patients in whom the axillary vein was used (group A; brachioaxillary AVG [B-Ax AVG]; n=20) with those in whom upper limb veins were used (group B; bra-chiobasilic AVG or brachioantecubital AVG; n=22).Results: The 1-year primary patency rate was higher in group A than in group B (57.9% vs. 41.7%; p=0.262). The incidence of postoperative complications was not significantly different between groups.Conclusion: AVG using the axillary vein showed no major differences in safety or func-tionality compared to AVG using other veins. Therefore, accounting for age, underlying disease, and expected patient lifespan, B-Ax AVG can be considered an acceptable surgical method.
