Research progress and clinical application of cooled radiofrequency ablation

Abstract

Radiofrequency ablation (RFA) is a minimally invasive clinical treatment that uses radiofrequency energy to generate heat, resulting in the thermal necrosis of targeted tissues. To enhance the therapeutic benefits of traditional RFA, cooled RFA (CRFA) technology has been developed. CRFA incorporates cooling technology to prevent thermal damage and rapid impedance changes caused by tissue overheating. This review article provides a comprehensive overview of various types of cooling electrode needles used in CRFA, as well as an evaluation of their efficacy and clinical applications. We discuss the advantages of CRFA, including its minimally invasive nature, improved safety profile, and highly effective treatment outcomes. Nevertheless, certain problems and limitations are also addressed to optimize the potential of CRFA as a clinical treatment option. Overall, CRFA has promising prospects. With continued advancements in technology and further research, this innovative treatment modality is expected to significantly impact the treatment of a wide range of medical conditions.
