SHORT SEGMENT OF BRACHIAL ARTERY WITH ITS EMBRYOLOGICAL AND CLINICAL SIGNIFICANCE

摘要

Objectives: To estimate the site of bifurcation and significance, To indicate surgical implication, To correlate with embryological basis. Material and methods: The case was observed after thorough and meticulous dissection of the upper limbs of both sides (axilla, cubital fossa, forearm and palm) of an 80 year old male cadaver in the department of fr.muller medical college, mangalore, india. photographic documentation of the variation was also made. Results: An unusually short segment of brachial artery in the right arm which bifurcated 21.5cm above the neck of radius at the level of insertion of coracobrachialis which bifurcated into radial and ulnar arteries of same calibre with high origin of radial artery.no other variation was found in relation to the cords of brachial plexus and their branches.dissection of left upper limb revealed no unusual observation. Conclusion: This could pose a challenging problem to vascular surgeons while performing reconstructive procedures.Itcan be evaluated by vascular mapping prior to an arteriovenous access creation.Altered hemodynamic environment may give rise to variant patterning of blood vessels
