“…3,4 A report presented by Celik et al 5 shows early division of the brachial artery into the radial and ulnar arteries after giving origin to the profunda brachii artery. In the present case, the profunda brachii artery was represented by two separate branches arising from the posterior circumflex humeral artery.…”

Arterial variations in the arm are of potential clinical implications as it is a frequent site of injury and also involved in many surgical and invasive procedures. During a dissection of the right upper extremity, an abnormal high origin of the radial and ulnar arteries was found. The brachial artery had a very short segment without any branches, divided into the radial and ulnar arteries at the upper third of the arm. The course and branching pattern of these radial and ulnar arteries in the arm are discussed. It was also observed that the profunda brachii artery was represented by two separate branches arising from the posterior circumflex humeral artery. Accurate knowledge of these variation patterns is of considerable clinical importance in the conduct of reparative surgeries around the shoulder and fracture management of the humerus. These additional data of arterial anomalies to contemporary anatomical literature are of interest to clinicians, in particular vascular and plastic surgeons and radiologists.

“…Although the incidence of this variant is very low and no clinical cases have been documented in the available literature, it may be important for clinicians and surgeons to be aware of the presence of this arterial variation when surgical and diagnostic procedures in axillary or upper arm region. It is possible that its superficial course would make it more vulnerable to trauma and thus to serious bleeding (Jurjus et al, 1986), and more subject to accidental intra-arterial injection (Cohen, 1948). It is also likely that compression of the main nerves of the brachial plexus, including the ulnar, median and radial nerves could cause paralysis of the forearm and hand, due to its location between large-sized superficial brachial and subscapular arteries.…”

Summary: A rare variation in the arterial pattern was found in the right arm of an 87-year-old male cadaver in a student dissection practice. In this case, the superficial brachial and superficial subscapular arteries coexisted in the absence of the normal brachial artery (A. brachialis profunda). After branching off a large-sized superficial subscapular artery, the axillary artery did not penetrate the brachial plexus and gave rise to a superficial brachial artery, which arose from the axillary artery at the point between the ansa pectoralis and ansa mediana, and descended ventral to the median nerve branching off the profunda brachii and superior and inferior ulnar collateral arteries. The superficial brachial artery finally divided into the radial and ulnar arteries in the cubital fossa. The superficial subscapular artery passed inferior and dorsal to the medial cord of the brachial plexus, giving off the lateral thoracic artery, and then branched off into the thoracodorsal, circumflex scapular and posterior circumflex humeral arteries. Thus the main nerves of the brachial plexus were sandwiched between the superficial brachial artery and the superficial subscapular artery system. The morphological and clinical significance of this variant are discussed.

“…In the latter case, the superficial brachial artery may be termed ' artery a '. This instance must be distinguished from that described by Jurjus et al (1986), where the 2 brachial arteries (designated as 1 and 2) ran next to each other in the normal path of the brachial artery such that neither could be characterised as superficial.

An unusual branching pattern of the superficial brachial artery accompanied by an ulnar nerve with two roots

Variations in the arterial pattern of the upper limb are common and have been reported by several investigators (Fuss et al. 1985; Poteat, 1986; Tountas & Bergman, 1993; Rodriguez‐Baeza et al. 1995). These variations are often associated with anomalies in the arrangement of the nerves of the brachial plexus (Miller, 1939; Lengele & Dhem, 1989). The presence of a superficial brachial artery (Schwyzer & De Garis, 1935; Skopakoff, 1959; Fuss et al. 1985) and the usual pattern of its branching in the upper arm or forearm have also been reported (McCormack et al. 1953; Keen, 1961; Karlson & Niechalev, 1982; Lippert & Pabst, 1985; Rodriguez‐Baeza et al. 1995). The great variability of this arterial pattern may be attributed to the failure of regression of some paths of the embryonic arterial trunks (Tountas & Bergman, 1993; Rodriguez‐Baeza et al. 1995). The aim of the present report is to describe the concomitant appearance of 3 unusual variations in the same upper limb of a male cadaver. In this arm: (1) a superficial brachial artery terminated its course by dividing into 3 branches at the cubital fossa; (2) the definitive brachial artery had an unusual origin; and (3) the ulnar nerve was abnormally formed from 2 roots. This novel variation is compared with other anatomical variations in the arterial supply of the upper limb. In a series of routine dissections of 100 embalmed human cadavers the following variations were observed in the right upper limb of a male subject.
