Endovascular Management of Isolated Axillary Artery Aneurysm

Abstract

The purpose of this paper is to report a case of axillary artery aneurysm, successfully treated by percutaneous transfemoral self-expandable polytetrafluoroethylene (PTFE) covered Wallgraft™ stent. A 20-year-old man presented with sudden-onset, severe aching pain of left upper limb that occurred while doing isometric exercise. He had feeble left brachial and radial pulses. Angiography revealed a 21 x 14 mm left axillary artery aneurysm with a 15 mm neck. There was an organized clot in the midpart of the left brachial artery. The aneurysm was successfully closed with a self-expandable 10 x 30 mm Wallgraft™ endoprosthesis PTFE graft stent, via the right femoral route. A check angiogram at 6 weeks of follow-up showed a patent stent with no endovascular leak. At 1 year of follow-up, the patient was asymptomatic with normal upper limbs pulsations. Axillary artery aneurysm may be treated with a stent graft, which is an effective, rapid, and definite treatment and is an acceptable alternative to standard open surgical repair.
