Abstract

Background: The axillary artery (AA) branches into six vessels within the axilla. The brachial artery then continues at the teres major muscle's lower border. The brachial artery (BA) splits into the ulnar and radial terminal branches at the level of the radius neck or the cubital fossa. The underlying BA is an uncommon variant of the axillary artery that can have an impact on neural structures. This study aims to analyze the morphological relationship between the superficial brachial artery (SBA) originating from the AA and the segmental variation of the AA.
Materials and Methods: The research done in the Anatomy Department of Zydus Medical College and Hospital in Dahod involved the examination of the 16 upper limb of 8 cadavers. These cadavers were obtained over the course of one year and were used for undergraduate study in the First MBBS program. The dissection was done in the axilla and the arm. During the routine anatomy, dissection was observed a variant of the SBA and its termination.
Observation and Results: For this investigation, six Arm specimens were dissected. We have noticed a superficial brachial artery with an axillary origin in 2 cadavers. In the left arm, there was only one case (1.0%) of the SBA, which assets the arm muscles. There was only one case (1.0%) of SBA in the right arm merging with the deep brachial artery (DBA) in the Cubital fossa and extending as the radial artery (RA) of the forearm.
Conclusion: Variations of SBA have significance essential during surgical procedures. Morphological variations, as well as topographical variations, are significant factors in surgery of “upper limb as well asregular clinical practice. The use of surgical techniques is crucial in order to prevent injury to arteries, particularly in the upper limb as well as axilla regions.
