[Evaluation of the efficacy of foraminal infusions of corticosteroids guided by computed tomography in the treatment of radicular pain by foraminal injection].

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 radicular pain refractory to medical treatment. Imaging showed either degenerative foraminal stenosis, herniated disk or postsurgical fibrosis.


RESULTS
102 patients (63.8%) had significant pain reduction. Pain relief was 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 should be an integral part of the management strategy for radicular pain resistant to medical treatment.
