Abstract
ABSTRACT
Variations of venous pattern in the arm are common. In this case report, we present
a variation of axillary artery and vein. During routine educational dissections of
axillary region, it was observed that a fenestrated axillary vein was perforated by a
variant axillary artery in right arm of an old male cadaver. The axillary artery which
was fenestrated through axillary vein had only two branches arising from its second
part and no branches from its remaining distal parts. The branches are thoraco-
acromial (usual) and another large collateral (unusual) branch. This collateral
branch is the origin of several important arteries as the subscapular, circumflex
scapular, posterior circumflex humeral and lateral thoracic arteries. We propose
to name this artery as collateral axillary arterial trunk. The course of this collateral
axillary arterial trunk and its branches and also clinical significance of this variation
are discussed in the paper.
