Evaluation of patency following revision technique ofhigh-velocity arteriovenous fistula

Abstract

to 70) years] subsequently developed steal syndrome. These patients were treated with arterial pressure-controlled polytetrafluoroethylene banding or constriction with polypropylene suturing technique. Patients were followed in the outpatient clinic at regular intervals.Results: Symptoms were not relieved during the first 15 days in 4 patients; therefore, reintervention was performed. Thrombosis occurred in one patient after reintervention. No early or late complications were detected in other patients, and fistulae were suitable for hemodialysis. Patency rates at 6 and 12 months were 96% and 92%, respectively, and thrombosis rates were 7% and 9%. There was no hospital mortality in our study, but one patient died from unrelated causes and two other patients quit follow-up after 6 months. Conclusion:We think that arterial pressure-controlled surgical revision is an effective and safe technique in patients with fistula-related hand ischemia.

“…Accordingly, literature recommended surgery only for severe cases (grade ⩾2). 12,13 Among the others, vein outflow binding has been largely described as an appealing alternative considering its benign nature: the procedure can be performed under local anesthesia, and it is minimally invasive preserving the effectiveness of two-needle hemodialysis. 14 However, several authors have reported high rates of failure and thrombosis.…”
