During dissection conducted in an anatomy department of the right upper limb of the cadaver of a 70-year-old male, both origin and course of the radial and ulnar arteries were found to be anomalous. After descending 5.5 cm from the lower border of the the brachial artery anomalously bifurcated into a radial artery medially and an ulnar artery laterally. In the arm, the ulnar artery lay lateral to the median nerve. It followed a normal course in the forearm. The radial artery was medial to the median nerve in the arm and then, at the level of the medial epicondyle, it crossed from the medial to the lateral side of the forearm, superficial to the flexor muscles. The course of the radial artery was superficial and tortuous throughout the arm and forearm. The variations of radial and ulnar arteries described above were associated with anomalous formation and course of the median nerve in the arm. Knowledge of neurovascular anomalies are important for vascular surgeons and radiologists.
在对一名70岁男性尸体的右上肢进行解剖时，发现桡动脉和尺动脉的起源和走行均异常。肱动脉下缘向下5.5厘米后，异常分叉为内侧的桡动脉和外侧的尺动脉。在臂部，尺动脉位于正中神经外侧。它在前臂走行正常。桡动脉在臂部位于正中神经内侧，然后在肱骨内上髁水平，从前臂内侧跨过至外侧，位于屈肌浅面。桡动脉在整个臂部和前臂走行浅表且迂曲。上述桡动脉和尺动脉的变异与臂部正中神经的异常形成和走行有关。了解神经血管异常对血管外科医生和放射科医生很重要。
