Aerial anastomosis around the shoulder is between
-Aerial anastomosis around the scapula is principally formed by the first pa of subclan and third pa of axillary aeries. -These anastomosis takes place at 2 sites :around the body of the scapula and over the acromion process of the scapula. -If the subclan and axillary aeries are blocked anywhere between these 2 sitesscapular anastomosis serves as a potential pathway of collateral circulation to ensure adequate blood supply to the upper limb -Reference: Textbook of anatomy,Upper limb and thorax, Vishram Singh, 2nd editon, page no.51
