Abstract


INTRODUCTION: Brachial artery being the direct continuation of axillary artery at the lower border of teres major.Deviations in the normal course and branching pattern of the brachial artery and its detail knowledge of such arterial variations is essential not only to anatomist but also to radiologists,orthopaedicians,Vascular and plastic surgeons.

 AIMS  AND OBJECTIVES: The present study was done to evaluate the incidence of branchial artery anatomical variations & enumerate its impact on clinical implications.

 METHODOLOGY: This study was conducted in dept of anatomy of Osmania medical college ,koti,Hyderabad. During routine undergraduate dissection on human cadavers(44upperlimbs)-20 males and 2 female cadavers were dissected for the study.The cadavers with visible trauma , pathology or prior surgeries were excluded from study. Routine dissection of the upper limb was followed . During the dissection of the anterior compartment of  the arm and flexor compartment of forearm,the brachial artery was identified and carefully dissected at first,the brachial artery was confirmed that it is continuation of the third part of axillary artery at the lower border of teres major and then , it was traced towards its branches.Any variations found were noted and photographed . The results were analysed and compared to previous studies.

RESULTS: Bilateral termination of brachial artery was found in a male cadaver at the distal part of front of arm above the elbow joint[on right side 3.5 cms and on left 2.5 cms from the elbow joint]

CONCLUSION: High division of brachial artery has profound clinical importance varying across the spectrum,from a simple procedure of recording blood pressure using auscultatory method to advanced radiovascular procedures & nevertheless vascular surgeries .These variation are to be considered before proceeding on to  any vascular surgeries and interpretation of arteriograms of these vessels. Therefore  sound knowledge of unusual variations  or deviation in brachial artery is important for both radiologist and surgeons for diagnostic and therapeutic uses .
