Axillary artery aneurysm is rare. Although there were some reports that this disease was caused by repeated trauma and iatrogenic factor, thoracic outlet syndrome and systemic disease like Marfan syndrome, the cause by fibromuscular dysplasia (FMD) is extremely rare. A 68-year-old woman had complaint of a fever and she was diagnosed as bilateral axillary artery aneurysms by contrast-enhanced computed tomography in another hospital, she was referred to our hospital. On general anesthesia and supine position, we achieved replacement of both aneurysms with 8 mm externally supported knitted Dacron grafts (Gelsoft ERS) using the subclavian approach. Histopathological examination revealed the aneurysm wall had neither arteriosclerosis nor arteritis. The elastic fibers of intima were thickened (intimal fibroplasia), those of media were irregular and sparse (medial fibromuscular dysplasia), adventitia was normal, these findings corresponded to FMD. At first year after operation, there is no recurrence of aneurysms, grafts are patency.
