Abstract:
Objective To observe the efficacy and safety of CT-guided pulsed radiofrequency combined with continuous radiofrequency treatment for thoracic postherpetic neuralgia(PHN).Methods A total of 110 patients with thoracic PHN were retrospectively enrolled and divided into observation group(pulsed radiofrequency combined with continuous radiofrequency treatment)and control group(pulsed radiofrequency treatment)(each n=55).The visual analogue scale(VAS)pain scores before and 1 day,7 days,1 month and 3 months after treatment,also the treatment effective rate and incidence of adverse reactions were compared between groups.Results No significant difference of VAS pain scores was found between groups before treatment(P=0.818),while 1 day,7 days,1 month and 3 months after treatment,observation group had lower VAS pain scores than control group(all P＜0.001).The treatment effective rate in observation group was higher than that in control group(98.18％[54/55]vs.85.45％[47/55],P=0.025),while the incidence of adverse reactions in observation group was lower than that in control group(1.82％[1/55]vs.12.73％[7/55],P=0.028).Conclusion CT-guided pulsed radiofrequency combined with continuous radiofrequency could effectively reduce pain degree of thoracic PHN and adverse reactions.
