Introduction: Brachial artery being the direct continuation of axillary artery at the lower border of Teres major is the vital feeder vessel of the upper limb. Deviations in the normal course & branching pattern of the brachial artery were observed during routine undergraduate curricular cadaveric dissection.
Aims& Objectives: The present study was done to evaluate the incidence of brachial artery anatomical variations & enumerate its impact on clinical implications.
Materials and Methods : In the present study, a total of 50 adult upper limbs of 25 cadavers were studied. The upper limbs were dissected & observed using standard procedures during routine undergraduate curricular cadaveric dissection in Prathima Institute of Medical Sciences – Karimnagar.
Results :Deviations in anatomical course with high branching pattern were observed in two specimens. An unusual branch of brachial artery was observed in one more specimen.
Conclusion :High division of the brachial artery has profund clinical importance varying across the spectrum, from a simple procedure of recording blood pressure using auscultatory method to advanced radiovascular procedures and nevertheless vascular surgeries. These variations are to be considered before proceeding on to any vascular surgeries and interpretation of arteriograms involving these vessels. An unusual superficial ulnar branch of brachial artery is vulnerable to injury and accidental arterial injections. Therefore, sound knowledge of such unusual variations or deviations in brachial artery is important for both Radiologists and Surgeons to reduce diagnostic & therapeutic errors.
