An anatomic study17 published in 2004 has demonstrated that the superficial cervical artery always runs lateral to the levator scapulae and rhomboid muscles, dividing into a short superior branch and long inferior branch that courses inferiorly with the accessory nerve to the level of the scapular spine. The dorsal scapular artery – the dominant supply to the lower third of the muscle—runs deep to the levator scapulae and minor rhomboid muscles.
The Triple Heater (TH)

Dorsal scapular artery: This artery arises either from the transverse cervical or subclavian artery, runs deep to the levator scapulae muscle, and supplies the rhomboid muscles. The dorsal scapular artery joins with other arteries (the suprascapular and the subscapular, via the circumflex scapular) around the scapula to form arterial anastomoses. This collateral circulatory route provides another avenue of blood flow in the event of an interruption of blood supply through either the subclavian or axillary arteries. This interruption may result from ligation, in cases of a lacerated axillary or subclavian artery, or from vascular stenosis in the axillary artery secondary to atherosclerosis. In either situation, blood flow in the subscapular artery reverses direction, thereby allowing blood to reach the third part of the axillary artery. (The subscapular artery receives blood from the suprascapular, transverse cervical, and intercostal arteries via several anastomotic junctures.) See Figure 10-41 to view the dorsal scapular artery.

Look for branches from the subclavian artery as it passes lateral to the anterior scalene muscle. In about 50% of people, a branch arises from the subclavian artery as the artery is crossing the first rib. If this artery passes inferiorly and dorsally, deep to the levator scapulae and rhomboid muscles, it is named the dorsal scapular artery. Characteristically, the dorsal scapular artery passes through the brachial plexus (between the upper and middle trunks). In other people, the dorsal scapular artery is one of the branches of the transverse cervical artery.
Ultrasound imaging of the upper trapezius muscle for safer myofascial trigger point injections: a case report

Using the superior margin of the upper trapezius as anatomic landmark, three main neurovascular structures were identified in proximity of the painful site: the superficial branch of the transverse cervical artery (TCA) just beneath the upper trapezius muscle, the spinal accessory nerve located in the fat tissue interposed between upper trapezius and levator scapulae muscles and the deep branch of the TCA (also known as the dorsal scapular artery) over the rib (Figure. 1(b,c)).
