After standard hemodynamic monitoring, the patient was placed in the supine position, and the cervical region was prepared using sterile technique. Under fluoroscopic guidance, the target cervical neural foramen was identified in anteroposterior and lateral views. Following local infiltration with 2 mL of 1% lidocaine, a radiofrequency cannula was advanced to the target cervical dorsal root ganglion. Correct needle placement was confirmed fluoroscopically and by sensory stimulation, which elicited concordant paresthesia in the corresponding dermatome. Pulsed radiofrequency was then applied for 240 seconds at a maximum temperature of 42°C using a voltage of 45 V. After completion of the procedure, the cannula was removed, a sterile dressing was applied, and patients were observed for 60 minutes before discharge.
