ABSTRACT
An unusual unilateral variation in the branching pattern of axillary artery was observed in a 60 year old female embalmed cadaver. The axillary artery had only two branches arising from its proximal (first) part and no branches from its remaining distal (second & third) parts. The branches are superior thoracic (usual) and another large collateral (unusual) branch. This collateral branch is the origin of several important arteries as the circumflex scapular, thoracodorsal, posterior circumflex humeral, thoraco-acromial and lateral thoracic arteries. We propose to name this artery as common subscapular trunk. The course of this collateral artery (common subscapular trunk) and its branches and also clinical significance of this variation are discussed in the paper.
RESUMEN
Una inusual variación unilateral en el patrón de ramificación de la arteria axilar se observó en un cadáver embalsamado de 60 años de edad. La arteria axilar tuvo sólo dos ramas derivadas de su parte proximal (primera) y no otorgó ramas de su parte distal (segunda y tercera). Las ramas son superiores torácica (habitual) y otra gran rama colateral (inusual). Esta rama colateral es el origen de varias arterias importantes como la circunfleja escapular, toracodorsal, circunfleja humeral posterior, taraco-acromial y torácica lateral. Proponemos el nombre variación arterial como tronco común subescapular. El curso de este tronco común subescapular y sus ramas y también el significado clínico de esta variación son discutidas en este trabajo.
