A. thoracica superior, the first artery to supply thorax, is a thin vein branching from the first part of a. axillaris. There are two arteries branching from the second part of a. axillaris: One of them is a. thoraco-ac¬romialis, being a short and thick branch, and the other one is a branch also known as a. thoracica lateralis or a. mammaria externa. A. thoracodorsalis is an another vein and proceeds as a continuation of a. subscapularis and accompanies n. thoracodorsalis. Knowing variations other than normal anatomical structure is significantly important for anatomists, clinicians and especially for surgeons. We want to present an axillary artery and subscapular artery variation we have found, by using dissection method, on bilateral upper extremity of a 40-year old, white, male cadaver used for educational purposes by the Department of Anatomy, Faculty of Medicine, Inonu University.
Key words: Vascular variations, axillary artery, subscapular artery
