“…When the dorsal scapular artery arises directly from the subclavian artery (31% of specimens, Chaijaroonkhanarak et al 2014;69%, Huelke 1958;75%, Reiner and Kasser 1996), it pierced the brachial plexus. When the dorsal scapular artery arose from the thyrocervical trunk, which is the other origin (23% of specimens, Reiner and Kasser 1996;30%, Huelke 1958;69%, Chaijaroonkhanarak et al 2014) the dorsal scapular artery passed over the brachial plexus and did not pierce between the nerves. The most common location of the dorsal scapular artery to pierce the brachial plexus is between the upper and middle trunks (46% of specimens, Huelke 1958; 63%, Chaijaroonkhanarak et al 2014;69%, Reiner and Kasser 1996).…”
