Schematic set up of liver RF treatment with assumed current pathways
Elevated temperature is able to impair the cells via several ways. The primary manner of cell death during thermal ablation for tumor is acute coagulative necrosis. When temperature is up to 41°C, it causes the blood vessel dilation and the increase of blood perfusion. Meantime, it can stimulate the production of heat-shock protein for protecting the cell from heat injury and repairing the damage tissue. Nevertheless, this temperature-stimulated protective mechanism is associated with heat intensity and heat exposure time. When temperature is up to 46°C and heat exposure is up to 10 min, irreversible necrosis of significant cell mass will produce. Cells recovery from heat injury may exhibit an increased tolerance to elevated temperatures. Temperatures at 46–52°C will attenuate the time...
