SUMMARY: Injuries of the axillar artery are mainly due to penetrating traumatisms, although they may also occur as a consequence of chronic traumatisms because of inadequate use of crutches or falls on the stretched upper limb, among other causes. The presence of artery variations at the axillar level becomes important since axillar ha ematomas might compress the brachial plexus, thus producing a neurological deficit, even permanent with the immediate surgical decompression. We described the axillar origin of the deep brachial artery found in a formolized adult cadaver of male sex, dissected in the Human Anatomy Discipline of the Faculty of Medicine, Universidad de la Frontera, Chile. The axillar artery of the left upper left limb gave off (distal to the origin of the posterior circumflex humeral artery) to the deep brachial artery. The course of this artery was anterior to the tendon of the Latissimus dorsi muscle where it emitted the later superior collateral ulnar artery, penetrating in the arm and following a normal course together with to the radial nerve
