It was supplied by thoraco-dorsal nerve and blood supply was coming from superior thoracic artery
The axillary artery normally branches off the superior thoracic artery in the first part, the lateral thoracic and thoracoacromial arteries in the second part, and the subscapular, anterior circumflex humeral, and posterior circumflex humeral arteries in the third part (Drake et al, 2015).
The superior thoracic artery was found to arise normally from the first part of the axillary artery.
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.
The first part of the artery gives superior thoracic artery. The second part of the artery gives lateral thoracic and thoracoacromial branches.
The superior thoracic artery was out of the position.
The first branch of the first part is the superior thoracic artery which supplies the first and second intercostal space and the superior part of the serratus anterior muscle.
It was found that the superior thoracic artery was out of position.
Interestingly, the superior thoracic artery
took origin from thoraco- acromial artery which shared a common site of origin with axillary artery I and II.
