This article investigates the degree and duration of pain relief from cervicogenic headaches or occipital neuralgia following treatment with radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerves. It also addresses the procedure's complication rate and patient's willingness to repeat the procedure if severe symptoms recur.
This is a single-center retrospective observational study of 40 patients with refractory cervicogenic headaches and or occipital neuralgia. Patients were all referred by a headache specialty clinic for evaluation for radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerves. After treatment, patients were followed for a minimum of 6 months to a year. Patient demographics and the results of radiofrequency ablation were recorded on the same day, after 3-4 days, and at 6 months to 1 year following treatment.
Thirty-five percent of patients reported 100% pain relief and 70% reported 80% or greater pain relief. The mean duration of improvement is 22.35 weeks. Complication rate was 12-13%. 92.5% of patients reported they would undergo the procedure again if severe symptoms returned.
Radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerve can provide many months of greater than 50% pain relief in the vast majority of recipients with an expected length of symptom improvement of 5-6 months.
本文研究了射频消融 C2 背根神经节和/或第三枕神经治疗颈源性头痛或枕神经痛后缓解疼痛的程度和持续时间。还探讨了该手术的并发症发生率，以及如果严重症状复发，患者是否愿意再次接受该手术。
这是一项针对 40 例难治性颈源性头痛和/或枕神经痛患者的单中心回顾性观察研究。所有患者均由头痛专科诊所转介，评估射频消融 C2 背根神经节和/或第三枕神经的可能性。治疗后，患者至少随访 6 个月至 1 年。患者的人口统计学资料和射频消融结果在同一天、治疗后 3-4 天以及治疗后 6 个月至 1 年进行记录。
35%的患者报告疼痛完全缓解，70%的患者报告疼痛缓解 80%或以上。改善的平均持续时间为 22.35 周。并发症发生率为 12-13%。92.5%的患者表示，如果严重症状再次出现，他们将再次接受该手术。
射频消融 C2 背根神经节和/或第三枕神经可以为绝大多数患者提供 5-6 个月的 50%以上疼痛缓解，持续时间可达数月。
