The subscapular artery continued 2 cm more from the thoracoacromial artery and then divided into the thoracodorsal and circumflex scapular artery. The posterior circumflex humeral artery was accompanied by the axillary nerve and they entered the quadrangular space.
One is the superior thoracic artery and the other is a large branch which is termed as common subscapular trunk from which circumflex scapular artery, anterior and posterior circumflex humeral arteries, profunda brachii artery, ulnar collateral artery and thoracodorsal artery branched.
In 15.38% (n= 2) of the dissections, we found two arterial structures: branches of the suprascapular artery and the circumflex scapular artery. A total of 88 venous structures of the superficial and deep venous plexus were observed in relation to the subcutaneous tissue and deltoid and infraspinatus muscles (Fig.
It was observed that in the right upper limb, the lateral thoracic artery, thoraco-dorsal, circumflex scapular and posterior circumflex scapular artery arises from a common trunk from the second part of axillary artery underneath the pectoralis minor muscle (picture 1).
