Donor artery aneurysm formation following the ligation of haemodialysis arteriovenous fistula: a systematic review and case reports

PurposeThe purpose of this study is to investigate the pathogenesis, presentation and diagnosis of donor artery aneurysm formation following arteriovenous fistula (AVF) ligation and reach a consensus on their management.MethodsA systematic review of literature in Ovid, MedLine, Embase, Scopus and CINHAL in the English language from 1951 to 2014 was performed. This was accompanied by two case reports. A total of 12 articles with 23 case reports were identified. Variables including patient's demographics, signs, symptoms, fistula type, duration of fistula use, time to aneurysm formation, renal transplantation, diagnostic modality, aneurysm type and size, type of surgery and outcome were reviewed.ResultsThe data demonstrate a male predominance (5:1) and a median age of 47 years (range, 27-75 years). The median duration of access was 54 months (range, 6-300 months). The median time from ligation to aneurysm was 120 months (range, 6-280 months). The commonest aneurysm was of the brachial artery (BA, n = 21, 84...
