OTTONE, Nicolás Ernesto et al. Analysis and Clinical Importance of Superficial Arterial Palmar Irrigation and its Variants over 86 Cases. Int. J. Morphol. [online]. 2010, vol.28, n.1, pp.157-164. ISSN 0717-9502.

The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40%. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation becomes important in the application of surgical techniques that can help treating pathologies of the hand.
