Circumflex Scapular Artery

Circumflex scapular artery

The Circumflex Scapular Artery is a branch of the subscapular artery that plays a crucial role in supplying blood to the scapula and surrounding muscles.

Anatomy

The circumflex scapular artery typically arises from the third part of the axillary artery, but it can also originate from the subscapular artery. It travels around the lateral border of the scapula, entering the infraspinatus fossa through the triangular space. It then anastomoses with the suprascapular artery and the dorsal scapular artery.

Clinical Significance

The circumflex scapular artery is of clinical importance in flap surgeries, where it can be used as a source of vascularized tissue. It is also relevant in cases of shoulder dislocation and fractures, where it can be damaged, leading to hemorrhage or ischemia.
