The aim of the study was to show the efficacy and results of aneurysm reconstruction that was developed for relieving the patients from pain and mass effects and to give an early hemodialysis option.

Material and methods: Medical records were retrospectively screened over a period of 17 years to identify patients diagnosed with and surgically treated for aneurysm of an AV fistula. Twenty-eight patients were included in this study. The mean average age was 44 ± 3 years (31-60). Seventeen (60.7%) patients were female. Twenty-two (78.5%) patients had hypertension and 9 (32.1%) patients had diabetes mellitus. Aneurysm was examined by using ultrasonography to reveal the flow dynamics. The aneurysm was resected and an appropriate sized graft was interposed under local anesthesia. The same vein was dissected and anastomosed over the graft in an end-to-side fashion.

Results: Mean aneurysm diameter was 40 ± 12 mm. All aneurysm tissues and thrombotic materials were removed from the surgical field. Mean graft length was 37 ± 11 mm. Three (10.7%) patients need surgical revision because of postoperative bleeding. Dermal necrosis occurred in 1 (3.5%) patient. Infection was noted in 1 (3.5%) patient. Vascular access was started from the recon-structed venous area 2 or 4 days later in all patients. The patency rate was 100% in three years.

Conclusions: Surgical reconstruction of the arteriovenous fistula aneurysm can be safely performed in hemodialysis patients with low complication rates. It gives early vascular access with high patency rates. All patients are relieved from pain and distended mass effect.
