Axillary artery aneurysm is a rare condition. Though mostly asymptomatic, it should be treated early as it can develop thrombosis, distal embolisation, pressure symptoms or rupture. We report here a case of a 24-year woman who presented with neurological deficit in her arm because of pressure by axillary artery aneurysm. Standard treatment of these aneurysms is excision and replacement with an interposition graft. We used reversed saphenous vein as interposition graft between axillary and brachial artery.
