Comparative study between one stage and two-stages superficialization of brachio-basilic arteriovenous fistula as a hemodialysis access procedure

Abstract

Background: The best technique for creating brachiobasilic arteriovenous fistulas (BBAVFs) is still up for debate. Because of this, the purpose of this study was to examine the patencies, primary failure rates, and complication rates of brachiaobasilic arteriovenous fistulas formed using the one-stage and two-stage superficialization techniques. Patients and Methods: In order to compare one stage and two-stage superficialization of brachiobasilic arteriovenous fistula, a prospective, randomized controlled clinical trial including 38 patients undergoing brachiobasilic arteriovenous fistula operations for end-stage renal disease was carried out. Two groups of patients were created using basic randomization. Patients in Group I underwent a single step of superficialization for their brachiobasilic arteriovenous fistula, whereas patients in Group II got a two-stage superficialization procedure. Results: Patients with two-stage BBAVF had a substantially longer fistula maturation period than patients with one-stage BBAVF. However, patients with two-stage BBAVF also had considerably greater fistula flow rate and primary functional patency when compared to patients with one-stage BBAVF. In terms of the complications in both groups, patients with one-stage BBAVF had a considerably greater incidence of thrombosis and post-operative hematoma than patients with two-stage BBAVF. However, there was no discermible difference in the two groups’ incidence of infection, steal syndrome, hematoma, or pseudoaneurysm. Conclusion:
