Subscapular artery

The subscapular artery is the axillary artery's largest branch and arises from its third part. It branches off backwards into two branches, approximately four centimeters from its origin; its first branch is the scapular circumflex artery and its second is the thoracodorsal artery. It distributes blood to the muscles of the scapular and the shoulder region. It is possible for an aneurysm to occur in the subscapular artery if the artery experiences an injury near its origin, without the axillary vessels also being injured. In such cases, surgery involving the litigation of the artery and an excision of the aneurysm is sometimes successful.
