Insufficient Radiofrequency Ablation Promotes Hepatocellular Carcinoma Metastasis Through N6‐Methyladenosine mRNA Methylation‐Dependent Mechanism

Hepatology, 2021
The dynamic N6‐methyladenosine (m6A) mRNA modification is essential for acute stress response and cancer progression. Sublethal heat stress from insufficient radiofrequency ablation (IRFA) has been confirmed to promote HCC progression; however, whether ...

Technical considerations for genicular nerve radiofrequency ablation: optimizing outcomes

Regional anesthesia and pain medicine, 2021
Genicular nerve radiofrequency ablation has emerged as a treatment option for patients with painful knee osteoarthritis who have failed conservative management but who may not qualify or wish to avoid a surgical procedure.

Update on Radiofrequency Ablation

Perspectives in Vascular Surgery and Endovascular Therapy, 2009
The two currently available methods to achieve ablation of incompetent veins using radiofrequency energy are radiofrequency ablation (VNUS Closure Plus(tm)) and radiofrequency powered segmental ablation (VNUS Closure Fast(tm)). Both treatment modalities expose vascular endothelium to high-frequency alternating current.

Stereotactic Radiofrequency Ablation

CardioVascular and Interventional Radiology, 2010
To describe the technique of percutaneous stereotactic radiofrequency ablation (SRFA) and its application in a patient with an unresectable multifocal intrahepatic cholangiocarcinoma (ICC).A 72-year-old man presented with two nodules of an ICC with a maximum diameter of 10 and 4 cm, respectively.

Biophysics of Radiofrequency Ablation

Critical Reviews™ in Biomedical Engineering, 2010
Radiofrequency (RF) ablation is a treatment modality that kills unwanted tissue by heat. Starting with cardiac arrhythmia treatment in the 1980s, RF ablation has found clinical application in a number of diseases, and is now the treatment of choice for certain types of cardiac arrhythmia and certain cancers. During RF ablation, an electrode is inserted

Bipolar Radiofrequency Ablation of the Kidney: Comparison with Monopolar Radiofrequency Ablation

Journal of Endourology, 2003
We report initial ex vivo and in vivo studies using bipolar radiofrequency (RF) ablation of porcine kidneys. An internal ground electrode is positioned in the kidney opposite the RF electrode, resulting in ablation of all the intervening renal tissue.Ex vivo preparations of 10 porcine kidneys were perfused continuously with Ringer's solution and ...

Radiofrequency Ablation of Liver Cancer

Techniques in Vascular and Interventional Radiology, 2007
The development of image-guided percutaneous techniques for local tumor ablation has been one of the major advances in the treatment of liver malignancies. Over the past two decades, several methods for chemical or thermal tumor destruction have been clinically tested.

Prospective Multicenter Experience With Cooled Radiofrequency Ablation Using High Impedance Irrigant to Target Deep Myocardial Substrate Refractory to Standard Ablation.

JACC Clinical Electrophysiology, 2018
OBJECTIVES This study sought to evaluate the efficacy and safety of using half-normal saline (HNS) as the cooling radiofrequency ablation (RFA) irrigant among patients who had failed prior, standard RFA.
