Unilateral Variation In The Branching Pattern Of Axillary Artery
Journal Title: IJAR-Indian Journal of Applied Research - Year 2016, Vol 6, Issue 4
Abstract
During routine cadaveric dissection, finding a variation in the normal anatomical structures is of great interest to all the anatomists. Here, we present a case regarding a unilateral anomalous branching pattern of the Axillary artery, found on the right side in an old male cadaver during a routine cadaveric dissection. Conventionally, Axillary artery is described as having three parts - first, second, third - with reference to the tendon of insertion of Pectoralis minor muscle. Each part then gives off its own branches as first part one, second part two and third part three. In the present case, the first part of Axillary artery does not give any branch. The second part is seen to divide into - a) Superficial and b) Deep branches. Both the branches are of equal diameter. a) The superficial branch after giving Thoracoacromial Artery in second part and Anterior Circumflex Humeral Artery in third part continued in the arm as the brachial artery. b) The deep (described by many as accessory axillary artery) branch distributed the following branches - i) Superior Thoracic Artery, ii) Lateral Thoracic Artery, iii) Accessory Thoracic Artery, iv) Subscapular Artery and v) Posterior Circumflex Humeral Artery.
