Abstract

Abstract : Objective . The aim of this study was to compare the efficacy of ultrasound-guided deep cervical plexus block with fluoroscopy-guided deep cervical plexus block for patients with cervicogenic headache (CeH). Methods . A total of 56 patients with CeH were recruited and randomly assigned to either the ultrasound-guided (US) or the fluoroscopy-guided (FL) injection group. A mixture of 2–4 mL 1% lidocaine and 7 mg betamethasone was injected along C2 and/or C3 transverse process. The measurement of pain was evaluated by patients' ratings of a 10-point numerical pain scale (NPS) before and 2 wks, 12 wks, and 24 wks after treatments. Results . The blocking procedures were well tolerated. The pain intensity, as measured by NPS, significantly decreased at 2 wks after injection treatment in both US and FL groups, respectively, compared with that of baseline ( P < 0.05). The blocking procedures had continued, and comparable pain relieving effects appeared at 12 wks and 24 wks after treatment in both US and FL groups. There were no significant differences observed in the NPS before and 2 wks, 12 wks, and 24 wks after treatment between US and FL groups. Conclusions . The US-guided approach showed similar satisfactory effect as the FL-guided block. Ultrasonography can be an alternative method for its convenience and efficacy in deep cervical plexus block for CeH patients without radiation exposure.
