Bilateral Axillary Artery Aneurysms Presenting as Upper Limb Ischemia.

An axillary artery aneurysm (AxAA) is a rare entity. Although some cases with AxAA are asymptomatic, complications including local pain, neurogenic symptoms, upper limb ischemia, and rupture may occur. Therefore, an early diagnosis and treatment are necessary. We herein report a case of bilateral AxAAs, in which the right AxAA showed acute upper limb ischemia and the left AxAA were asymptomatic. Both AxAAs were successfully treated by aneurysmectomy and interposition grafting. In the endovascular era, open surgical treatment for AxAAs remains a promising procedure.
