SURBANO, Marta; CRISTIANI, Federico; AYALA, Santiago  y  CASTROMAN, Pablo. Pulsed radiofrequency of dorsal root glanglion a clinical case of chronic lumbosacro syndrome refractory to epidural steroids. Anest Analg Reanim [online]. 2016, vol.29, n.2, pp.18-30. ISSN 0255-8122.

Lumbosacral radicular syndrome, produced by discs herniations, discs protrusions or spinal stenosis is frequently treated by injecting steroids in the epidural space. However, 20% of the patients are resistant to this treatment, so few therapeutics options for them are left. Pulsed radiofrequency of the Dorsal Root Ganglion is a validated therapeutic option, when the syndrome is refractory to epidural steroid injections and spinal surgery is not indicated or elected. We report a clinical case of a lumbosacral radicular syndrome, refractory to epidural steroid injections, successfully treated with pulsed radiofrequency of lumbar Dorsal Root Ganglion, utilizing the Spanish version of the Brief Pain Inventory, as an outcome evaluation tool.

Palabras clave : Dorsal root ganglion; Pulsed radiofrequency; Lumbosacral radicular syndrome.
