MEDINA RUIZ, B et al. High origin of the radial artery (superficial brachialarterial artery):Presentation of 3 cases. An. Fac. Cienc. Méd. (Asunción) [online]. 2017, vol.50, n.1, pp.69-80. ISSN 1816-8949.  https://doi.org/10.18004/anales/2017.050(01)69-080.

We present three cases of high birth of the radial artery, all on the right limbone at the upper third of the brachial artery, the second at the middle third of the artery, and in the third case the radial artery arises at the level of the axillary artery. In all cases they have a superficial path in the arm and forearm. In the hand they form the deep arterial arch of the palmar in the usual way. These cases represent 7.5% of the 40 dissected members. The high birth of the radial artery is the most frequent variant within the arterial tree anomalies of the upper limb. Its importance lies in the increase of the percutaneous procedures on the radial artery in coronary catheterisms and in the increasingly used radial flap in the reconstructive surgeries. Its superficial pathway favors trauma and confusion with veins, a situation that can cause accidental drug injections in these arteries with their serious consequences.
