Primary Patency Time of Basilic Vein Transposition versus Prosthetic Brachioaxillary Access Grafts in Hemodialysis Patients

Abstract

Purpose The aim of this study was to compare the primary patency time of basilic vein transposition and prosthetic brachioaxillary access grafts in hemodialysis patients. Methods In this randomized clinical trial, 60 hemodialysis patients who met the inclusion/exclusion criteria were recruited and randomly assigned to two intervention groups; Basilic vein transpositions (BVT) or Arteriovenous access grafts (AVG). Clinical follow-up for patency of the created accesses in at least one year, was performed at two weeks, one, two, three months and then every three months after surgery. Finally, patency rates and access-related complications were compared in the two groups studied. Results Thirty BVTs and thirty AVG were performed in each group studied. The groups were well matched for age, sex and comorbidity. After at least one year of follow-up, the access failure rate in the BVT and AVG groups was 23.3% and 30%, respectively. In addition, the mean primary patency time in the BVT and AVG groups was 244.13 ± 103.65 and 264.97 ± 149.28, respectively and there was no statistically significant difference between the two groups studied (P=.533). The common cause of access failure were thrombosis and infection but there were no statistically significant differences between the two groups (P>.05). Conclusion Our results show that AVG offer similar patency and complication rates to BVT. Thus, authors consider them as the preferred hemodialysis access when there are no suitable forearm veins to create arteriovenous fistulas.
