The most common method to make an ablation is to generate consistent RF thermocoagulation consisting of an alternating current at a frequency of 500,000 Hz through a one-pole electrode producing an oscillating electric field with moving electrolytes to cause significant heat by friction. Temperatures above 45°C produce permanent tissue destruction. The clot has a 1-6 mm diameter at temperatures of 60 to 80 ° C for 60 seconds. The average lesion volume is 75 mm3, 44-127 mm3 in different studies. Other techniques such as radiosurgery ablation are being tested, where radionecrosis is generated.
