en News and Reports News and Reports <p dir="ltr" style="text-align: justify">Variations in arterial anatomy are less frequent, contrary to the venous system, and most&nbsp;of these variations affect visceral arteries. Variations in the brachial artery are the most&nbsp;frequently reported and so far a minimum of six different patterns have been described. The&nbsp;most common of these patterns is the superficial brachial artery, which lies superficially to&nbsp;the median nerve. Much less prevalent is the high origin of the radial artery (brachioradial&nbsp;artery) or the existence of a doubled brachial artery (accessory brachial artery). The current&nbsp;study presents a pattern of brachial artery variation which was previously undescribed.&nbsp;During dissection of the right upper limb of a 50 year-old male embalmed cadaver, the&nbsp;bifurcation of the brachial artery in the proximal portion of the middle third of the arm was&nbsp;observed. In this case, the medial branch reaches the medial aspect of the arm, posterior to&nbsp;the median nerve. Afterwards, this medial branch redirects laterally and crosses the median<br> nerve again, this time lying anterior to the nerve till it reaches the lateral aspect of the arm.&nbsp;At the elbow level, the medial branch originates from the radial artery. The lateral branch&nbsp;of the brachial artery remains lateral to the median nerve and continues as ulnar artery and&nbsp;originates from the interosseous artery. It was also observed that the left brachial artery was<br> smaller in size, and bifurcated high in the arm into the superficial radial and ulnar arteries.&nbsp;It was also interesting to note that the common interosseous artery was originated from the&nbsp;left radial artery in the cubital fossa, which descended deep to pronator teres where it was&nbsp;divided into the anterior and posterior interosseous arteries. These variations are discussed<br> comprehensively and compared with the previous reports. Also, it is asserted how clinically&nbsp;the findings are significant.</p> Anatomical variations, Brachial artery, Cadaver 97 100 http://anatomyjournal.ir/browse.php?a_code=A-10-87-2&slc_lang=en&sid=1 Fatemeh Fadai Fathabadi 10031947532846001284 10031947532846001284 No Department of Biology and Anatomical Sciences, Faculty of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
