Valnicek has described that three major arterial branching patterns of the subscapular artery were observed with one, two, and three major branches to the serratus anterior in 60 percent, 29 percent, and 9 percent of the cases, respectively.
CONCLUSION: In general, our results are similar to the findings in the literature consulted as far as the subscapular artery is concerned.

In up to 30% of cases, the subscapular artery can arise from a common trunk with the posterior circumflex humeral artery.
The medial branch was the subscapular artery, which in turn gave three circumflex scapular arteries; one medial and two lateral branches to the scapular border, the artery then continued as thoraco-dorsal artery, with the thoracodorsal nerve and supplied the medial wall of axilla and latissimus dorsi muscle (Soubhagya et al., 2006).
In an extensive dissection of 512 adult human cadavers, De Garis & Swartley (1928) reported a variable percentage in the origin of lateral thoracic artery from thoraco--acromial artery, from the subscapular artery or from second part of axillary artery.
