Abstract
IntroductionSpontaneous atraumatic true axillary artery aneurysm is a relatively unusual disorder. Although most cases are asymptomatic, complications of axillary artery aneurysms may result in acute vascular insufficiency and neurological deficits. Prompt treatment, therefore, should be employed in the management of this condition. To date, the standard treatment for peripheral aneurysms is still surgical resection with end-to-end anastomosis. However, aneurysmectomy and interposition grafting with autologous or artificial vessels are more invasive and time-consuming. The ideal treatment for axillary artery aneurysm should be relatively noninvasive, safe and free of significant complications, cost-effective, cosmetically acceptable, and incur less absence from usual daily activities. Endovascular stent grafts have also been successfully used to treat these aneurysms. Management of select aneurysms using stent grafts has become more prevalent with the developing endoluminal technology.Case presentationWe report a case of a spontaneous atraumatic axillary artery aneurysm where the patient was a 48-year-old ethnic Han Chinese woman with a gradually enlarging left axillary pulsatile mass. She was treated with endovascular stent grafts. The postoperative course of the patient was uneventful during the six-month follow-up.ConclusionsWe show that there are significant early advantages with the endovascular management technique versus the conventional operation in the management of axillary artery aneurysm.

Summary
Arterial aneurysms can occur in any vascular territory. Aneurysms of the upper extremities are rare in relation to other peripheral aneurysms. Case presentation A 48-year-old ethnic Han Chinese woman was admitted to our hospital with a gradually enlarging left axillary pulsatile mass She complained of left upper extremity weakness, and pain. There were no signs of vasculitis or connective tissue diseases associated with arterial involvement such as hyperelastic skin, hypermobile joints, or marfanoid habitus Her laboratory test results, including erythrocyte sedimentation rate, Creactive protein, complete blood count, serological test for syphilis, rheumatoid factor, antinuclear antibody, antithrombin III, protein C, and protein S, were normal. A computed tomography (CT) angiography revealed a 30×51mm size true aneurysm of the left axillary artery (Figure 1). Digital subtraction angiography confirmed a 3×5cm fusiform aneurysm at the proximal part of her left axillary artery (Figure 2). Completion angiography of the left axillary artery showed good flow through the stent graft and complete. Follow-up, she was symptom-free and no further studies were needed
