ID: 209893 The Effect of Local Anesthetics and Contrast Agents on Radiofrequency Ablation Lesion Size

Abstract

Radiofrequency ablation (RFA) is a validated treatment option for the treatment of chronic pain in patients with lumbar spondylosis. Lesion size is suggested to correlate with good clinical outcomes. This has created an abundance of scientific interest to develop products with larger lesion characteristics. Needle characteristics, energy transfer, and heat rate are known to modify lesion size. Here, we demonstrate that common intra-operative solutions such as Lidocaine, Iodine and Gadolinium-based products can also affect lesion shape.
