Origin

The subscapular artery arises from the axillary artery, at the level of the distal edge of the subscapularis muscle. In about 20% of individuals, the posterior circumflex humeral and subscapular arteries originate from a common trunk (Tubbs, Shoja and Loukas, 2016).

Course

The subscapular artery is the largest branch of the axillary artery and has a short inferior course of approximately 4 cm.

Branches

The terminal branches of the subscapular artery are the circumflex scapular and thoracodorsal arteries.

Supplied Structures

The subscapular artery supplies the subscapularis muscles and the scapular region via its terminal branches.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
