Pulsed Radiofrequency to the Dorsal Root Gaglion in Postherpetic Neuralgia

Herpes Zoster is an infectious disease caused by the reactivation of the latent varicella-Zoster virus. Postherpetic neuralgia (PHN) is the most common complication of herpes Zoster and can impair the quality of life due to severe pain symptoms. Post-herpetic neuralgia is difficult to treat and over 50 percent of patients fail to achieve satisfactory pain relief. The authors present a clinical case involving a 74-year-old patient suffering from Post-herpetic neuralgia; this study reveals that dorsal root ganglion pulsed radiofrequency was effective in treating Post-herpetic Neuralgia
