Abstract
Post-herpetic neuralgia (PHN) is one of the most intractable pain disorders, particularly among the elderly. The authors present a case of intractable post-herpetic neuralgia (PHN) that was treated successfully by conventional radiofrequency (RF) ablation. A 57-year-old man visited with a 3-year history of herpes zoster of left chest wall. He underwent diagnostic RF stimulation and the seventh and eighth left intercostal nerves were confirmed as pathologic lesions. One week later, conventional RF ablation of the left seventh and eighth thoracic dorsal root ganglia (DRGs) was performed. The PHN was relieved for 4 months and then recurred. Repeat conventional RF ablation was found to have controlled the PHN at his 12-month follow-up. RF DRG ablation achieved marked pain relief in this patient. However, further research is needed to prove the benefit of RF ablation in post-herpetic neuralgia.
Key Words: Dorsal root ganglion, Postherpetic neuralgia, Radiofrequency.
