Original Research Article - Variation in the branching pattern of the 3rd part of axillary artery
Dr. V Ravikumar Dr. Siri AM
Axillary artery is the principal artery of the upper limb. It is also the axis artery of the upper limb. Its normally divided into 3 parts by the pectoralis minor muscle. There are many known variations of the third part of axillary artery. The study was conducted in the dept of Anatomy JJMMC and SIMS & RC between 2011 – 2015[5 years] on cadavers. The present case was found in a male cadaver aged around 60years.During the routine cadaveric dissection of undergraduate students we found that 3rd part of axillary artery divided into subscapular artery and common trunk which in turn gave origin to other branches of upper limb. The subscapular artery gave rise to circumflex scapular artery, thoracodorsal artery and posterior circumflex humeral artery. The common trunk on the other hand gave origin to anterior circumflex artery, nutrient artery of humerus, profunda brachii artery, superior and inferior ulnar collateral arteries. The knowledge of such type of variation is important for surgeons, orthopedicians and interventional radiologists who operate in this region.
