CT-guided transforaminal cervical and lumbar epidural injections.

Transforaminal injections are widely used. Serious complications including strokes and paraplegia have been reported after transforaminal injections of corticosteroids, and the Afssaps (2011) has issued a warning about their use [1]. The needle must be positioned in the posterior aspect of foramen, and its correct placement validated by an injection of contrast product. It is preferable to choose cortivazol (Altim(®)) as the corticoid for injection. This procedure is simple, reproducible, and durably effective in 60 to 70% of cases. Complications and adverse effects are rare but potentially serious: allergies, blood pressure surge, vasovagal syncope, transient exacerbation of pain, infection, stroke, and paraplegia. The aim of this course is to stress the need for rigor - in the indication, the technical performance of the procedure, and the overall management of the patient.
