The purpose of our study was to evaluate the efficacy of direct intraforaminal steroid injections into the periganglionic space in the treatment of radicular pain.
Periganglionic infiltrations were performed in 41 patients with acute or chronic radicular pain. Neuroradiologic imaging in all patients showed foraminal stenosis due to degenerative disorders or herniated disk. All injections were performed under CT control.
Seventy percent of patients had significant pain reduction, with the greatest success (90% of patients) in those whose foraminal stenosis was due to degenerative disorders; 45% of patients with foraminal herniated disks had pain relief.
Intraforaminal steroid injection is useful in the treatment of radicular pain, particularly in cases of foraminal degenerative stenosis.
我们研究的目的是评估直接经椎间孔向神经节周围间隙注射类固醇治疗神经根性疼痛的疗效。
对41例急性或慢性神经根性疼痛患者进行神经节周围浸润。所有患者的神经放射学成像均显示因退行性疾病或椎间盘突出导致的椎间孔狭窄。所有注射均在CT引导下进行。
70%的患者疼痛显著减轻，其中椎间孔狭窄由退行性疾病引起的患者成功率最高（90%）；45%的椎间孔椎间盘突出患者疼痛得到缓解。
经椎间孔注射类固醇对神经根性疼痛的治疗有效，尤其是在椎间孔退行性狭窄的病例中。
