“…Injuries to the subclavian and axillary arteries account for 5% to 10% of vascular injuries in civilian trauma centers, mostly from penetrating trauma. 2 3 The subclavian artery is located in the transition zone between the thorax, neck, and upper extremity, and, as such, it is protected by the thoracic outlet comprised of the clavicle, first rib, subclavius muscle, deep cervical fascia, costocoracoid ligament, and clavi-coraco-axillary fascia. Because of this protection, stab injuries do not lead to injury as commonly as gunshot wounds.…”
