Patients and methods: Between January 2010 and July 2019, a total of 103 patients (69 males, 34 females; mean age 52.3±20.6 years; range, 18 to 87 years) who underwent elective AVF surgery due to AVF aneurysms (≥4 cm) were included in this retrospective study. Operative techniques and patients" outcomes were reviewed and analyzed.

Results: Aneurysm resection and graft interposition, ligation, and aneurysmorrhaphy (partial aneurysm resection and plication) were performed in 62, 5, and 14 patients with radiocephalic AVF aneurysms, respectively. Aneurysm resection and graft interposition, aneurysm ligation, and aneurysmorrhaphy were performed in 10, 7, and 5 patients with brachiocephalic and brachiobasilic AVF aneurysms, respectively. Wound infection, hematoma, and seroma were seen as postoperative complications in 5, 4, and 11 patients, respectively. The mean postoperative fistula flow rate of the patients with brachiocephalic and brachiobasilic AVFs was 402±48 mL/min. The mean postoperative fistula flow rate of the patients with radiocephalic AVFs was 325±69 mL/min. There was no in-hospital mortality.

Conclusion: It should be kept in mind that AVF aneurysms may cause serious consequences, if left untreated before the development of complications. The surgical treatment of AVF aneurysms not only reduces the risk for developing complications, but also provides the protection of the AVF in most patients.
