An Unusual Branching Pattern of the Axillary Artery and Brachial Artery- A Case Report
Journal Title: International Journal of Medical and Health Sciences - Year 2012, Vol 1, Issue 2
Abstract
Branches of the upper limb arteries have been used for coronary bypass and flaps in reconstructive surgery. Anomalies in the artery are infrequent and their descriptions have generally been centered on the anomalous origins of some of its branches. We observed an unusual branching pattern of the axillary artery and brachial artery. In axilla, first part of axillary artery did not give any branch, the second part of axillary artery gave off only two branches - (A) a common trunk which later gave off superior thoracic, clavicular, and pectoral branches and (B) a large common trunk which later gave off lateral thoracic, posterior circumflex humeral, thoracodorsal, subscapular, and then continued as circumflex scapular artery. The third part of axillary artery gave three branches- a) Acromial, b) Deltoid, and c) Anterior circumflex humeral. In the arm brachial artery gave off a common trunk which latter gave off profounda brachi, superior ulnar collateral arteries. The embryogenesis of such a combination of anomalies is not clear, but the anatomic consequences may have important clinical implications. These anomalies are described in detail and their clinical relevance is highlighted.
