Post-herpetic neuralgia is a chronic neuropathic pain disorder that is the sequela of the varicella zoster virus reactivation in the dorsal root ganglion. A variety of treatment modalities have been implemented, but pharmacologic treatments are often limited due to side effects and interventional procedures have yielded mixed results without promising long-term benefits being consistently seen. A dorsal root ganglion stimulator for treatment of post-herpetic neuralgia is a novel treatment option as it is able to specifically target the area affected. We present 3 patients who underwent implantation of permanent dorsal root ganglion stimulators and had a greater than 50% decrease in scoring on numerical rating scale (NRS) up to 18 months post-procedure and significantly reduced analgesic requirements.

背根神经节刺激治疗难治性带状疱疹后遗神经痛

带状疱疹后神经痛是一种慢性神经性疼痛疾病，是背根神经节中水痘带状疱疹病毒再激活的后遗症。已经实施了多种治疗方式，但药物治疗通常由于副作用而受到限制，并且介入手术产生的结果喜忧参半，但没有始终如一地看到有希望的长期益处。用于治疗带状疱疹后神经痛的背根神经节刺激器是一种新的治疗选择，因为它能够专门针对受影响的区域。我们介绍了 3 名接受永久性背根神经节刺激器植入的患者，并且在手术后长达 18 个月的数字评定量表 (NRS) 上的评分下降了 50% 以上，并且镇痛需求显着减少。
