Background: The study of brachial artery is an important arterial conduit from the clinical point of view to anatomists, general surgeons, radiologists, plastic surgeons, and even cardiovascular thoracic surgeons in the conduct of reparative surgery. Therefore, the present study was designed to study the course, branching pattern and termination of Brachial Artery and its clinical significance of these variations.

Materials and Methods:  The present study was conducted on 30 upper limbs of 15 cadavers embalmed & belonging to the Department of Anatomy, Govt. Medical College, Alappuzha over the period of 1 year. By conventional dissection method a longitudinal incision was given along the midline of arm through the deep fascia, inferior up to cubital fossa.  Brachial artery was identified, cleaned & dissected and assessed the length of brachial artery, level of termination of brachial artery, variation in the branching pattern and the course in relation to the median nerve was noted.

Results: The average length of the brachial artery was 25.23 cms. 73.3% of the brachial artery followed the classical pattern as given in Gray’s Anatomy.  Variation in the branching pattern, presence of accessory brachial artery, origin of profunda brachial artery was noted.  3.3% trifurcation of brachial artery into Radial, Ulnar & Common interosseous at the level of neck of radius. Brachial artery terminated at the level of neck of radius in 76.67%, radial tuberosity 13.33%, mid arm3.33%, proximal arm 6.67%.

Discussion and Conclusion:  Variations of brachial artery in its relationship with the median nerve, pattern and level of termination are common. These may complicate arm surgical exposure, flap and vascular surgery. Hence, Knowledge of possible variations in the branching pattern of various arteries is important during vascular and reconstructive surgery.
