Unilateral high origin of radial artery from axillary artery.
Variations in the vascular system of upper limbs are relatively common, with  considerable significance towards the clinical and surgical point of view.  The major arterial variations reported are of high origins of radial and ulnar  arteries. During routine dissection of an upper extremity in the Department  of Anatomy, Medical University of the Americas, Nevis, West Indies, a variation  in the origin of the radial artery from the axillary artery was observed in  the right upper limb of a 55-year-old female cadaver. The normal and variant  origin of the radial artery has pragmatic importance for surgeons and  radiologists. Also, the superficial position of an artery makes it vulnerable to  injury during cannulation, which may lead to pseudoaneurysm.
