Experience of using C-arm-X-ray guided radiofrequency thermocoagulation in the treatment of 2700 patients with trigeminal neuralgia

Objective To explore the methods and clinical effects of radiofrequency thermocoagulation in the treatment of primary trigeminal neuralgia guided with C-arm-X-ray.Methods Retrospective analysis of the C-arm-X-ray guided percutaneous foramenovale a half ganglion radiofrequency thermocoagulation technique(the temperature setting of 65-80℃ and time was set to 30-60 s) of the clinical data of 2 700 cases of patients with trigeminal neuralgia were near long-term efficacy evaluation,to observe the complications.Results The pain compleately disappeared in 2 697 cases,the total efficiency of 98.56%,ineffective in 9 cases(0.33%),recurrence in 30 cases(1.11%).Conclusion C-arm-X-ray guided selective the ganglionnervi trigernini radiofrequency thermocoagulation is a minimally invasive,safe,broad indications and has significant effect of treatment,especially the recurrence of the trigeminal nerve associated with cardiovascular disease and otler treatments pain in patients with this methods is safe and reliable.
