Clinical Significance of Superficial Brachial Artery andHigh Division of Brachial Artery

Introduction: the brachial artery runs at lower border of the teres major muscle as acontinuation of the third part of the axillary artery. it divided into radial and ulnar arteries atthe neck of the radius. for surgeons performing operations on the upper extremity, clinicalknowledge of the morphology of brachial arteries in the upper limb is important. this studyaims to study the course, branching pattern, and termination of the brachial artery in humancadavers.methods: in this study, 30 upper limb specimens were collected from adult human embalmedcadavers used for undergraduate dissection at the institute of anatomy, madras medicalcollege in chennai, india.results: of 30 dissected specimens, 29(96.7%) had normal brachial artery course and onehad superficial brachial artery (3.3%). the brachial artery division was seen in 28 specimens(93.3%) below the intercondylar line (at the neck of the radius). in 2 cases (6.7%), the brachialartery division into radial and ulnar arteries occurred above the intercondylar line.conclusion: the variations in origin, course, branching pattern, and termination of the upperlimb’s brachial artery are important both structurally and therapeutically. surgeons, physicians,radiologists, and cardiologists should pay attention to these variations. due to the use ofmodern surgical techniques in vascular surgery, plastic and reconstructive surgeries, diagnostic& therapeutic tests, these variances have attracted the attention of surgeons, physicians, radiologists, and interventionists.
