Circumflex Scapular Vein

Description

Posterior upper thorax and shoulder girdle are shown in a male model, with the right scapula and adjacent ribs framed by the cervical and upper thoracic vertebral column and the occipital region of the skull. The circumflex scapular vein courses along the posterior surface of the scapula, winding around the lateral border toward the scapular neck and the region of the triangular space, where it communicates with the axillary venous system. Surrounding veins and arteries of the neck, upper limb, and thoracic wall form a broader vascular context, while the scapular spine, acromion, clavicle, and costal contours anchor orientation. Attention to the circumflex scapular vein matters because it is a key component of the scapular anastomoses and a reliable landmark when teaching or navigating posterior shoulder approaches. In trauma and reconstructive surgery, this territory intersects common flap pedicles (scapular and parascapular fasciocutaneous flaps based on circumflex scapular vessels) and can become relevant during dissection of the triangular space bordered by teres minor superiorly, teres major inferiorly, and the long head of triceps laterally. Small vessel, big consequences. Educators can drop this view directly into upper limb anatomy labs, regional anatomy lectures on the axilla and scapular spaces, or surgical atlases covering posterior shoulder exposure and flap design. Publishers will also find it useful for correlating surface landmarks of the scapula with deep vascular pathways when explaining collateral flow around the shoulder following proximal axillary artery compromise.
