A patient is presented who had recurrent carpal tunnel syndrome symptoms in his left hand 1 year after having undergone release of the transverse carpal ligament. On exploration, this was found to be due to an aneurysm of a median artery and possibly scarring due to this compression around the branches of the bifurcated median nerve. This represents the first case in the literature to comment on (1) the absence of bilaterality of the anatomic finding and (2) carpal tunnel syndrome relative to median artery aneurysm. With this in mind, a plea is made for careful exploration of the carpal tunnel, maintaining an incision as far to the ulnar side of the median nerve as technically possible with thorough visualization of the contents of the tunnel and any anatomic variance involved. The incidence of the combination of aberrant median artery with high bifurcation of the median nerve is unknown, as is the incidence of aneurysm of the median artery.
一名患者在接受腕横韧带松解术后1年，左手出现复发性腕管综合征症状。术中探查发现，这是由于正中动脉动脉瘤所致，并且可能是由于该动脉瘤对正中神经分支的压迫导致瘢痕形成。这是文献中首例提及（1）该解剖学发现不存在双侧性以及（2）与正中动脉动脉瘤相关的腕管综合征的病例。鉴于此，呼吁在腕管探查时要仔细，在技术可行的情况下，尽可能在正中神经尺侧进行切口，同时要全面观察腕管内容物及任何相关的解剖变异。正中动脉走行异常合并正中神经高位分支的发生率尚不清楚，正中动脉动脉瘤的发生率也未知。
