Abstract
Introduction: Arteriovenous fistula dysfunction has been associated with a range of problems such as thrombosis, stenosis, dilatation, and infection.
Case presentation: We present the case of a 64-year-old patient with chronic kidney disease on hemodialysis and with aneurysmal dilatation of the ulnar-basilic arteriovenous fistula, having an increased risk of rupture. A temporary dialysis catheter is placed in the left femoral vein, an aneurysmal basilic vein is ligated at the anastomosis, aneurysmal dilatation is emptied by compression, and a right radiocephalic arteriovenous fistula is performed. The patient undergoes hemodialysis on the second day and subsequently three times a week for six weeks until the new arteriovenous fistula develops. He returns for aneurysmal sac resection.
Conclusion: The purpose of this paper is the presentation and management of a 15-year-old ulnar-basilic arteriovenous fistula with multilocular aneurysmal development and an imminent rupture.
