Efficacy of Combined Dorsal Root Ganglion Pulsed Radiofrequency and Cervical Epidural Steroid Injection on Radicular Neck Pain.

Abstract

To evaluate the efficacy and safety of combined transforaminal anterior epidural steroid injection (TAESI) and dorsal root ganglion pulsed radiofrequency (DRG-PRF) therapy on the radicular neck pain. The results of 84 patients with cervical radicular pain who underwent combined DRG-PRF and TAESI under fluoroscopy were evaluated retrospectively. Primer outcome is the pain measurements of the patients before and after the procedure at the 1 < sup > st < /sup > , 3 < sup > rd < /sup > , and 6 < sup > th < /sup > months were evaluated with the Verbal Pain Scale (VPS). Our secondary outcome was the evaluation of patient satisfaction in the 1 < sup > st < /sup > , 3 < sup > rd < /sup > , and 6 < sup > th < /sup > months after the interventional treatment, and it was considered significant if it was evaluated as ?good? above 50%. We found statistically significant decrease in the pain scores of the patients in the 1 < sup > st < /sup > , 3 < sup > rd < /sup > , and 6 < sup > th < /sup > months compared to the pre-intervention (VPS 0) (p < 0.001). After the procedure, the patients expressed their satisfaction level as 69.1% at the 1 < sup > st < /sup > month, 71.5% at the 3 < sup > rd < /sup > month, and 72.6% at the 6th month as ?very good/good?. While the operation was mostly performed at the C5-6 level on both sides, it was seen that 61.9% of the operations were applied from the right side and 38.1% from the left side. No adverse effects or fatal neurological complications were observed. Although the efficacy and complications of cervical TAESI and DRG-PRF treatment are controversial in the literature, we think that this combined treatment can provide effective pain palliation in experienced hands with appropriate patient selection, considering the risk / benefit ratio.
