Arteriomegaly and aneurysms proximal to long-standing posttraumatic arteriovenous fistulas (AVF) have been described. Much fewer are the reports of the late occurrence of brachial artery aneurysms following the closure of a hemodialysis AVF. Here, we report the case of a 55-year-old male patient. He had received a cadaver donor kidney transplant in 1996; his distal radiocephalic (RC) wrist AVF in the left arm had been ligated in 2001; he developed an aneurysm of the left brachial artery 9 years after the ligation of the AVF (2009). He underwent the surgical intervention of aneurysmectomy at the level of the left brachial artery with construction of a bypass with autologous saphenous vein. In conclusion, the development of a RC wrist AVF is an intrinsically dynamic process characterized by the increase in both blood flow rate and internal diameter of the brachial artery; the latter might be associated with enhanced fracture of the elastic fibers with the consequent risk of the development of an aneurysm. Thus, arteriomegaly and aneurysm of the brachial artery proximal to long-standing AVFs might be seen as a "continuum" of these morphologic modifications.
