In this report, we describe a 41-year-old woman with symptoms concerning for acute carpal tunnel syndrome. Operative exploration resulted in resection of an aneurysmal, thrombosed, persistent median artery seen on preoperative imaging and full recovery by the patient.
A persistent median artery is an uncommon congenital hand condition resulting from the failure of the median artery to regress, which can then travel through the carpal tunnel and be associated with a bifid median nerve, irritation of the nerve, and need for surgical exploration if it thromboses, which is rare. This should be considered in patients with acute median nerve compression, without other etiologies.
在本报告中，我们描述了一名41岁女性，其症状提示急性腕管综合征。手术探查发现术前影像学检查显示的动脉瘤样、血栓形成的永存正中动脉，并将其切除，患者完全康复。
永存正中动脉是一种罕见的先天性手部疾病，由正中动脉未能退化所致，它可穿过腕管，并与正中神经分支、神经刺激相关，若发生血栓形成（罕见）则需要手术探查。对于无其他病因的急性正中神经受压患者应考虑此病。
