Objective
To further evaluate the efficacy and safety of computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency treatment for patients with refractory episodic and chronic cluster headache (CH).
Methods
Forty‐five patients with refractory episodic CH and 14 patients with chronic CH who underwent computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency between January 2011 and December 2018 at the Beijing Tiantan Hospital were included and analyzed in this retrospective cohort study.
Results
A total of 59 patients underwent 106 computerized tomography–guided pulsed radiofrequency procedures throughout the observational period. Effective remission was observed in 95.6% and 64.3% of patients with refractory episodic and chronic CH, respectively. Repeated computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency procedures for recurrent CH was also proven to be effective. No severe side effects or complications were observed in this study.
Conclusion
The computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency procedure is an effective, safe, and repeatedly effective strategy for refractory CH. For patients who have not responded to conservative treatment, this minimally invasive intervention is a reliable alternative.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
