Variant high-origin radial artery: a bilateral case

Abstract

During a dissection of both upper extremities, an abnormally high origin of the radial a. was found on each side. However, the arterial patterns were not the same. On the right side, the radial a. arose 2 cm above the junction of the two roots of the median n. On the left side, the radial a. arose from the brachial a. 3 cm distal to the origin of the profunda brachii a. The course of these arteries in the forearm were normal. However, in the hand, on the right side, the contributions of the radial and ulnar aa. to the superficial and deep palmar arches were, unusually, equal. On the left side, the superficial palmar arch was formed as usual mainly by the ulnar a. and the deep palmar arch was formed mainly by the radial a. The high origin of the radial aa. in this case is explained on the basis of the embryologic development and is distinguished from the other common arterial variations in the upper limb.

Primary Pattern of Arteries of Upper Limb with Relevance to their Variations

“…It is reported that the incidence of variations ranges from 4.4 % to 8.3 % in various samples (Ozcan et al, 2006). Further they have included nonhomogeneous sample or incomplete extremities and have failed to describe the related morphological feature of each of the separate patterns, throughout their whole length in the arm and forearm (Içten et al, 1996). Dimension of the brachial artery and flow-mediated dilatation (FMD) are associated with severity of cardiovascular diseases.…”

Case report of high origin of radial, ulnar, and profunda brachii arteries, its clinical implications and review of the literature

“…13 There are many such reports on high origin of the radial artery. 14,15 In the present case, the radial artery crossed superficially to the median nerve and then descended laterally to it. While descending in the arm, the radial artery did not give origin to any branches.…”
