PERIGANGLIONIC FORAMINAL STEROID INJECTIONS PERFORMED UNDER CT CONTROL

PURPOSE: The purpose of our study was to evaluate the efficacy of dire ct intraforaminal steroid injections into the periganglionic space in the treatment of radicular pain. METHODS: Periganglionic infiltrations were performed in 41 patients with acute or chronic radicular pain. N euroradiologic imaging in all patients showed foraminal stenosis due t o degenerative disorders or herniated disk. All injections were perfor med under CT control. RESULTS: Seventy percent of patients had signifi cant pain reduction, with the greatest success (90% of patients) in th ose whose foraminal stenosis was due to degenerative disorders; 45% of patients with foraminal herniated disks had pain relief. CONCLUSION: Intraforaminal steroid injection is useful in the treatment of radicul ar pain, particularly in cases of foraminal degenerative stenosis.
