PURPOSE
This study investigated the frequency of persistent median artery (PMA) in patients with carpal tunnel syndrome (CTS) and controls.
METHODS
A total of 84 CTS patient wrists, and 136 wrists of control subjects without CTS, were examined on ultrasonography (US) and color Doppler US (CDUS), and by electrophysiological evaluations. The frequency of PMA in CTS was evaluated.
RESULTS
Of 84 CTS patient wrists, 2 (2.4 %) had a PMA (both on the right side). Of 136 control wrists, 12 (9 %) had a PMA, which was unilateral in eight (three right and five left), and bilateral in two, cases. There was no significant difference between the CTS patient and control groups with respect to the frequency of PMA (P > 0.05).
CONCLUSIONS
There was no significant difference between the CTS patient and control groups in the frequency of PMA. We suggest that an ipsilateral PMA does not increase the risk of CTS.
目的
本研究调查了腕管综合征（CTS）患者和对照组中永存正中动脉（PMA）的出现频率。
方法
对84例CTS患者的手腕以及136例无CTS的对照受试者的手腕进行了超声检查（US）、彩色多普勒超声检查（CDUS）以及电生理评估。评估了CTS患者中PMA的出现频率。
结果
在84例CTS患者的手腕中，2例（2.4%）存在PMA（均在右侧）。在136例对照手腕中，12例（9%）存在PMA，其中8例为单侧（3例右侧，5例左侧），2例为双侧。CTS患者组和对照组在PMA出现频率方面无显著差异（P>0.05）。
结论
CTS患者组和对照组在PMA出现频率方面无显著差异。我们认为同侧PMA不会增加CTS的风险。
