Objectives: In this study, we present our experience with arteriovenous fistula (AVF) aneurysm treatment and introduce a new technique, Tan-Gor technique, for the resection of giant AVF aneurysms. Patients and methods: Between January 2011 and December 2015, a total of 48 patients (26 females, 22 males; mean age 51.5 years; range, 16 to 85 years) who were operated for either AVF aneurysms or high-flux AVFs were retrospectively analyzed. Fifty surgical procedures were performed including 40 (80%) in the left upper extremity, nine (18%) in the right upper extremity, and one (2%) in the left lower extremity. Results: Of all operations, 64% (n=32) were performed over the cephalic veins. Of these patients, 22 had aneurysmectomy and excision, six had plication, four had banding, and two had both banding and plication. Fourteen operations were performed on the basilic vein: six patients had aneurysmectomy alone, four had aneurysmectomy and graft interposition, two had plication, one had banding, and one had both banding and plication. Conclusion: Preservation of the AVFs should be the first choice in aneurysmal dilatation of AVFs. When reconstruction of the AVF is not possible and surgical aneurysmectomy is a must, this novel technique can be safely performed via excision of the vein with overlying skin to decrease complications, to reduce operational time, and to improve wound healing and cosmetic results.
