A middle-aged woman presented with symptomatic complete heart block and underwent an uneventful dual chamber pacemaker implantation. Three weeks post procedure, she developed left arm pain and weakness, with neurological localization to the lower trunk of left brachial plexus. Possibilities of traumatic compression by the device/leads or postoperative idiopathic brachial plexopathy were considered. After ruling out traumatic causes, she was started on oral steroids, to which she responded remarkably. This case highlights the importance of recognizing this rare cause of brachial plexopathy following pacemaker implantation, because not only does an expedited diagnosis and medical treatment lead to prompt recovery with minimal neurological deficits, but it also circumvents an unnecessary surgical re-exploration.

起搏器植入后特发性臂丛神经病

一名中年妇女出现症状性完全性心脏传导阻滞，并接受了双腔起搏器植入术。术后三周，她出现左臂疼痛和无力，神经系统定位于左臂丛下干。考虑了装置/导线造成创伤性压迫或术后特发性臂丛神经病变的可能性。在排除了创伤性原因后，她开始服用口服类固醇，对此她做出了显着的反应。这个案例强调了在起搏器植入后识别这种罕见的臂丛神经病变原因的重要性，因为快速诊断和药物治疗不仅可以在最小的神经功能缺损的情况下迅速恢复，而且还可以避免不必要的手术重新探查。
