Study of Formation of Median Nerve Variation and Branching Pattern of Axillary Artery Variations

Deepthi.S ^[2] | Suseelamma.D | Jayasree.N

Abstract: Introduction: Axillary artery is a continuation of subclavian artery at outer border of first rib. Variations in branching pattern of axillary artery and formation of median nerve variation is uncommon. The knowledge of these variations is anatomical, radiological and surgical interest to explain clinical signs and symptoms. Material and Methods: Bilateral dissection of axilla was studied in 10 embalmed cadavers during routine dissection. Observations & Results: Unilateral variations were observed in three cadavers. In the first case double thoraco acromial arteries arose from second part of axillary artery on left side. In second case thoraco acromial artery arose from first part of axillary artery on right side, and it does not piercing the clavipectoral fascia. In third case three roots of median nerve which are two roots are arose from medial cord and one root from lateral cord as usual. Conclusion: The detailed knowledge about variations of branching pattern axillary artery and formation of median nerve helpful for surgeons, radiologist performing cardiovascular diseases and inter ventional procedures.
