Median nerve compression in the carpal tunnel by a thrombosed persistent median artery and a large aberrant artery substituting for the radial artery has been described but there have been no reports of median nerve compression in the palm of the hand by an anomalously enlarged ulnar artery. A 46 year old man is described who presented with clinical and electrophysiological features consistent with a median neuropathy at the wrist but surgical exploration revealed median nerve compression in the palm of the hand by an anomalously enlarged palmar branch of the ulnar artery. This case highlights another treatable cause of median nerve compression and illustrates that symptoms suggestive of carpal tunnel syndrome may be produced by median nerve compression in the palm of the hand.
已有文献描述了腕管内正中神经被血栓形成的永存正中动脉和替代桡动脉的粗大异常动脉压迫的情况，但尚无尺动脉异常增粗导致手掌部正中神经受压的报道。本文描述了一名46岁男性，其临床表现和电生理特征与腕部正中神经病变相符，但手术探查发现是尺动脉掌支异常增粗导致手掌部正中神经受压。该病例突出了正中神经受压的另一个可治疗病因，并表明手掌部正中神经受压可能产生提示腕管综合征的症状。
