Chronic migraine is common but difficult to treat. Most patients respond poorly to drugs. Occipital nerve block such as stellate ganglion block is an effective treatment without continuous effect for migraine. Pulsed radiofrequency (PRF) technique has been shown to be effective in relieving headache and prolonging the effect of nerve block. This case report is about a patient who suffered from chronic migraine with occipital pain and was successfully treated with PRF of C2 (axis) dorsal root ganglion (DRG) under ultrasound guidance confirmed by computed tomograpy scan. The patient did not feel headache after 1-year follow-up. This suggests that C2 DRG PRF might be considered as an alternative treatment for chronic migraine with occipital pain.
慢性偏头痛很常见但难以治疗。大多数患者对药物反应不佳。枕神经阻滞如星状神经节阻滞是偏头痛的一种有效治疗方法，但效果不持久。脉冲射频（PRF）技术已被证明可有效缓解头痛并延长神经阻滞的效果。本病例报告介绍了一名患有慢性偏头痛伴枕部疼痛的患者，在计算机断层扫描确认的超声引导下，成功接受了C2（枢椎）背根神经节（DRG）的PRF治疗。随访1年后患者未再感到头痛。这表明C2 DRG PRF可能被视为慢性偏头痛伴枕部疼痛的一种替代治疗方法。
