Unilateral Double Axillary and Double Brachial Arteries: Embryological Basis and Clinical Implications

This report presents double axillary and double brachial arteries on the right side of an adult male cadaver. In this case, the right axillary artery bifurcated into axillary artery I and axillary artery II posterior to the pectoralis minor muscle. Both the axillary arteries with their branches trav...

In this case, the right axillary artery bifurcated into axillary artery I and axillary artery II posterior to the pectoralis minor muscle. Both the axillary arteries with their branches traversed upto lower border of teres major muscle and continued further as seperate entities into the cubital fossa as brachial artery I and brachial artery II respectively. The axillary artery I which continued as brachial artery I was superficial and tortuous in its course, while the axillary artery II was slender and deeply situated. The thoraco-acromial, lateral thoracic and subscapular arteries took origin from axillary artery I. The superior thoracic artery was seen arising from the thoraco-acromial artery. The anterior and posterior circumflex humeral arteries arose from axillary artery II.The profunda brachii artery was given off by the brachial artery II, while at the level of intercondylar line, the ulnar artery was given off by brachial artery I.
