We present a unique unilateral case of a superficial brachiomedian artery that coincides with a variable palmaris longus muscle in a male cadaver. The superficial brachiomedian artery branched at the distal part of the right arm and coursed superficially in the cubital and antebrachial regions. Then it passed through the carpal canal and formed a complete superficial palmar arch by joining the trunk of the ulnar artery. The variable bitendinous palmaris longus was composed of a central belly and two asymmetrical tendons inserting mainly on the ulnar side of the flexor retinaculum. The knowledge of this arterial variant is of high clinical relevance for the catheterization, for the harvesting of the forearm artery as a graft, for the collateral circulation in cases of arterial occlusion, for surgical management of the carpal tunnel syndrome, or in cases of injury of the superficially located variant artery.
我们展示了一例独特的单侧浅表肱正中动脉病例，该病例与一名男性尸体中变异的掌长肌同时存在。浅表肱正中动脉在右臂远端分支，在肘和前臂区域浅表走行。然后它穿过腕管，通过与尺动脉主干相连形成一个完整的浅表掌弓。变异的双腱掌长肌由中央肌腹和两条不对称肌腱组成，主要插入屈肌支持带的尺侧。了解这种动脉变异对于导管插入术、采集前臂动脉作为移植物、动脉闭塞时的侧支循环、腕管综合征的手术治疗或浅表变异动脉损伤的情况具有高度临床相关性。
