O. Berger et al., Evaluation of CT-guided periganglionic foraminal steroid injections for treatment of radicular pain in patients with foraminal stenosis, J RADIOLOG, 80(9), 1999, pp. 917-925
Purpose. To evaluate the efficacy of foraminal steroid injections performed
under CT guidance for the management of radicular pain.
Methods. Periganglionic infiltrations were performed in 160 patients with r
adicular pain refractory to medical treatment. Imaging showed either degene
rative foraminal stenosis, herniated disk or postsurgical fibrosis.
Results. 102 patients (63.8%) had significant pain reduction. Pain relief w
as lasting in 68 (66.6%). CT showed the position of the needle tip, as well
as the diffusion of the therapeutic compounds.
Conclusion. We consider that CT-guided periganglionic steroid injections sh
ould be an integral part of the management strategy for radicular pain resi
stant to medical treatment.
