Radio Frequency ablation (RFA)Radio Frequency ablation (RFA) A radio frequency generator provides a source of
radiofrequency An active electrode (needle) is inserted into the body (liver), the
dispersive electrode is on the skin surface (grounding pad) An electric field is produced around the electrodes, the needle
has a much higher field around it than the grounding electrode The RF causes charged ions to oscillate and friction causes the
tissues to heat. Temperatures above 45c cause irreversible cell damage and
apoptosis Needle tip temperatures are recorded as a reflection of the tissue
temperatures

Impedance may also be used to measure tissue dessication and indirectly temperature
Temperature of >90 are undesirable as charring and gas formation occur and inhibit needle function

Principles of TreatmentPrinciples of Treatment
Zone of ablation exceeds diameter of lesion (ie ‘surgical’ margin)
Adjacent tissues (both inside and outside liver) must be considered when zone of ablation is planned
RFA is non specific (ie will kill all tissues –including the ones you want to preserve within the heat radius of 45 degrees)

Principles of TreatmentPrinciples of Treatment
Different tissues and materials conduct heat differently
Heat ‘sink’ effect of flowing blood may preserve tissue viability within the ‘kill zone’ (ie adjacent to IVC)

o The occlusion of tumor blood supply to induce infarction, with or without the addition of chemotherapy
o Embolization induces ischaemia and may increase the effectiveness of some chemo drugs and increase the inter tumoral concentrations
o Liver has dual blood supply protecting against infarction and severe liver injury
o Tumor blood supply primarily from hepatic artery, there may be a solitary feeder

• Radioembolization with Yttrium-90 is a novel form of liver-directed brachytherapy
• Radiolabeled glass beads 30-50µm in diameter are injected into the hepatic artery, become trapped at the precapillary level, and emit lethal internal radiation (Beta emitter T1/2 64.6 hours .9367 MeV); limiting exposure to the surrounding normal parenchyma, and allowing higher dose delivery than with an external beam
