[Pain management with nerve root block under ct and neurostimulator guidance]
1Département de Radiologie et Imagerie Médicale, Hôpital Sud, BP 90347, 35203 Rennes cedex 2, France.
Purpose:
To evaluate the efficacy of nerve roots block under CT and neurostimulator guidance for the management of pain.
Material:
and method. Nerve root blocks were performed in 27 patients (pudendal nerve, intercostal nerve, ilio-hypogastric nerve, thoracic and lumbar sympatholysis). These were performed with corticosteroids (Altim((R))) (20 patients) or phenol (7 patients).
Results:
Seventeen patients (63%) had pain reduction during at least 15 days. The pain relief was longer with phenol. Complications appeared in the 3 lumbar sympatholysis (inguinal pain) and one of the thoracic sympatholysis (Claude Bernard Horner syndrome).
Conclusion:
The nerve root blocks seem to have some efficacy and a further evaluation is necessary to assess their impact on the ability of patients to return to work and their need for pain medication. When performing these procedures, one must be careful to avoid potential complications and verify that the procedure is needed.
