Artery Circumflex Scapula (A. Circumflexa Scapulae, Pna, Bna, Jna)

The circumflex scapular artery is a vessel that runs along the back surface of the scapula and bends around it. It belongs to the upper limb system and is a branch of the axillary artery.

The circumflex scapula artery starts from the axillary artery and passes along the posterior surface of the scapula, bending around it. It then continues downwards, passes through the armpit and exits to the surface of the body. It supplies blood to the muscles, bones and tissues located around the shoulder blade.

The anatomical name of the circumflex scapula artery depends on the system to which it belongs. In accordance with international anatomical terminology (PNA, BNA, JNA), the circumflex scapular artery is called “circumflexa scapulae” (circumflex scapular artery).

In clinical practice, the circumflex scapular artery may be injured or damaged during surgery on the shoulder or arm. This can lead to bleeding, pain and loss of limb function. Therefore, it is important to know the anatomy and location of this artery to avoid complications.

Thus, the circumflex scapular artery is an important vessel in the upper limb system, which provides blood supply to the muscles, bones and tissues around the scapula. Its knowledge can help in the diagnosis and treatment of injuries and diseases of the upper limb.
