An unusual variation of the superficial ulnar artery

Anomalous superficial ulnar arteries were found bilaterally during routine dissection of the upper limbs of a 60-year-old male cadaver. In the left arm, the superficial ulnar artery originated from the axillary artery. It crossed the median nerve anteriorly and ran anteromedial to this nerve and the brachial artery. The superficial ulnar artery was also rudimentary and gave rise to only a narrow muscular branch to the biceps brachii. In the hand, it anastomosed with the radial artery, completing the superficial palmar arch. The radial artery was larger than usual and the deep palmar arch was formed only by the radial artery. In the right arm, the superficial ulnar artery originated from the brachial artery at the level of the inter-epicondylar line. Additionally there were “inverse palmaris longus muscles” bilaterally. This was a rare case in which the superficially ulnar artery originated from a different source on each side accompanied by anomalies of the palmar arches on one side.     

正中动脉发自尺动脉并吻合构成掌浅弓变异1例

正掌浅弓的构成形式具有多样性,但优势正中动脉型掌浅弓并不常见~([1-2])。作者在解剖1具成年男性福尔马林灌注的标本时,发现左前臂正中动脉起自尺动脉与正中神经紧密伴行,在拇短屈肌内侧和桡动脉掌浅支合成1/2的掌浅弓(图1)。现报告如下。1资料与方法经福尔马林固定的男性尸体1具,年龄约60岁,身高175 cm,体型标准,发育正常。采用大体解剖方法切开皮肤,清除臂前区和前臂前区浅筋膜,观察血管、神经的走行与分支。     

Bilateral case of superficial ulnar artery originating from axillary artery

During the dissection of an 86-year-old male human cadaver, superficial ulnar arteries were found in both upper limbs. These arteries branched from the axillary arteries. In the left arm, the artery crossed ventral to the medial root of the median nerve before running towards the medial part of the arm. The persistence of the median artery was noted. In the right arm, the ulnar artery had a common origin with the subscapular artery. It crossed anterior to the lateral root of the median nerve and then, in the arm, ran alongside the anterolateral aspect of the median nerve, near the biceps brachii muscle, which was supplied by this superficial ulnar artery. Then the artery crossed the median nerve and the brachial artery. The embryology, incidence and clinical relevance of this anatomical variation are discussed. So this was a rare case where the ulnar arteries originated from the axillary artery on both sides, but then followed different courses in the arm and, on the right side, the superficial ulnar artery partly supplied the biceps brachii muscle.     

Report of a rare human variation: the superficial ulnar artery arising from the axillary artery

A rare variation of the ulnar artery is presented on routine anatomical dissection in one male cadaver. The superficial ulnar artery was found to originate from the axillary artery. The free forearm flap is increasingly popular among plastic surgeons. As a result of this case, and a review of the literature to gain further knowledge of anatomical variations, it is advised that more attention should be paid clinically to this artery to prevent its injury.
