Complex regional pain syndrome secondary to brachial plexus injury is often severe, debilitating and difficult to manage. Percuteneous radiofrequency sympathectomy is a relatively new technique, which has shown promising results in various chronic pain disorders. We present four consecutive patients with complex regional pain syndrome secondary to brachial plexus injury for more than 6 months duration, who had undergone percutaneous T2 and T3 radiofrequency sympathectomy after a diagnostic block. All four patients experienced minimal pain relief with conservative treatment and stellate ganglion blockade. An acceptable 6 month pain relief was achieved in all 4 patients where pain score remained less than 50% than that of initial score and all oral analgesics were able to be tapered down. There were no complications attributed to this procedure were reported. From this case series, percutaneous T2 and T3 radiofrequency sympathectomy might play a significant role in multi-modal approach of CRPS management.
继发于臂丛损伤的复杂性区域疼痛综合征通常较为严重，使人虚弱且难以治疗。经皮射频交感神经切除术是一种相对较新的技术，在各种慢性疼痛疾病中显示出良好的效果。我们报告了 4 例继发于臂丛损伤且病程超过 6 个月的复杂性区域疼痛综合征患者，他们在诊断性阻滞之后接受了 T2 和 T3 经皮射频交感神经切除术。所有 4 例患者在接受保守治疗和星状神经节阻滞治疗后疼痛缓解轻微。4 例患者的疼痛缓解可接受，6 个月时疼痛评分仍低于初始评分的 50%，且所有口服止痛药均能逐渐减少。未报告与该手术相关的并发症。本病例系列研究提示，T2 和 T3 经皮射频交感神经切除术可能在复杂性区域疼痛综合征的多模式治疗中发挥重要作用。
