What is Radiofrequency Ablation?
Radiofrequency Interstitial Tissue Ablation (RFA) is a minimally invasive procedure in which a thin electrode is inserted into an unresectable lesion under ultrasound or CT guidance. Electrical energy is delivered through the electrode to the lesion which produces heat within the cells surrounding the electrode. When all cells within the lesion, as well as a margin around it, are heated beyond the lethal threshold (53°C), the procedure is complete.
RFA procedure can be used in Liver, Lung, Kidney and Bone.
