Two patients are described in whom symptoms of the carpal tunnel syndrome were provoked by haemodialysis for which an antebrachial arteriovenous fistula had been established. The symptoms in one case were partially relieved by ligation of the radial artery distal to the fistula, and in both they were abolished by decompression of the median nerve by section of the flexor retinaculum at the wrist. There is evidence that the median nerve is abnormally susceptible to ischaemia in the carpal tunnel syndrome, and it is suggested that in these patients the symptoms were provoked by a vascular steal mechanism related to the fistula.
本文描述了两名患者，他们因建立了前臂动静脉内瘘进行血液透析而引发了腕管综合征的症状。其中一例患者通过结扎内瘘远端的桡动脉，症状得到部分缓解；而两例患者均通过在腕部切断屈肌支持带对正中神经进行减压后，症状消失。有证据表明，在腕管综合征中正中神经对缺血异常敏感，提示在这些患者中症状是由与内瘘相关的血管窃血机制引发的。
