Variations in the branching pattern of axillary artery are observed by many anatomists all over the world. A unique bilateral variation in the axillary artery was observed during the routine dissection of the upper limbs on an approximately 65 year old male cadaver. An abnormal communicative channel was observed between lateral thoracic artery and anterior circumflex humeral artery. It passed between the two roots of median nerve. Arterial anomalies in the upper limb are due to defective remodelling of vascular plexus of the upper limb bud during embryogenesis. Knowledge of variations in axillary artery is quintessential for surgeons, radiologists and anaesthesiologists to avoid treacherous complications during procedures.

The aim of the study was to evaluate the terminal segmentation of the axillary artery and to present four cases of anomalous branching of the axillary artery, the superficial brachial artery (arteria brachialis superficialis), which is defined as the brachial artery that runs superficially to the median nerve. Totally, 130 cadaveric upper arms embalmed by classical formaldehyde technique from collections of the Department of Anatomy, Third Faculty of Medicine, Charles University in Prague, were macroscopically dissected with special focus on the branching arrangement of the axillary artery. The most distal part of the axillary artery (infrapectoral part) terminated in four cases as a bifurcation into two terminal branches: the superficial brachial artery and profunda brachii artery, denominated according to their relation to the median nerve. The profunda brachii artery primarily gave rise to the main branches of the infrapectoral part of the axillary artery. The superficial brachial artery descended to the cubital fossa where it assumed the usual course of the brachial artery in two cases and in the other two cases its branches (the radial and ulnar arteries) passed superficially to the flexors. The incidence of the superficial brachial artery in our study was 5% of cases.The reported incidence is a bit contradictory, from 0.12% to 25% of cases. The anatomical knowledge of the axillary region is of crucial importance for neurosurgeons and specialists using the radiodiagnostic techniques, particularly in cases involving traumatic injuries. The improved knowledge would allow more accurate diagnostic interpretations and surgical treatment.

A case of anomalous terminal branching of the axillary artery, concerning the variant called superficial brachioradial artery (arteria brachioradialis superficialis) was described, with special regard to its embryological origin. The left upper limb of a male cadaver was dissected in successive steps from the axillary fossa distally to the palmar region. A variant artery, stemming from the end of the third segment of the axillary artery, followed a superficial course distally. It skipped the cubital fossa, ran on the lateral side of the forearm, crossed ventrally to the palm, and terminated in the deep palmar arch. This vessel is a case of so-called "brachioradial artery" (inexactly called a "radial artery with a high origin"). The origin of the brachioradial artery directly from the axillary artery belongs to the rare variants of the arterial pattern of the upper limb. Its incidence is approximately 3%. Moreover, this vascular variant was associated with another one concerning the brachial plexus. The medial cutaneous nerve of the forearm joined the median nerve in the middle third of the arm and ran further distally as a common trunk, as the normal median nerve does. Anatomical knowledge of the axillary region is crucial for radiodiagnostic and surgical procedures, especially in cases of trauma. The superficially located artery brings an elevated risk of bleeding complications in unexpected situations.
