What is radiofrequency ablation of liver needle

Radiofrequency thermal ablation (RFA) is a minimally invasive tumor in situ treatment technique, which uses ultrasound or CT imaging technology to locate and guide the electrode needle directly into the tumor, and the local tissue of the lesion will generate high temperature through radiofrequency energy, dry and finally solidify and inactivate the soft tissue and tumor. The principle is that when the electron generator generates radio frequency current, high-speed ion vibration and friction will be generated in the surrounding tissue through the electrode needle, which will then be converted into heat energy and conducted outward with time, so as to make the local tissue thermal solidification, necrosis and degeneration. Current techniques using radiofrequency ablation with a single electrode needle can produce coagulated necrotic foci up to 5cm in diameter. The efficacy of radiofrequency ablation in the treatment OF liver tumors has been observed to be very good, with reported 1 -, 2 -, 3 -, and 5-year survival rates of 94%, 86%, 68%, and 40%, respectively, in patients with primary liver cancer, which is similar to the efficacy of radical resection. At the same time, the goal of minimally invasive treatment and radical treatment of liver cancer was achieved. At present, due to the development of liver radiofrequency therapy, there are some changes and controversies in the treatment choice of some patients with small liver cancer or very serious liver cirrhosis. However, the choice of radiofrequency ablation for these patients is increasingly showing advantages in clinical treatment. At the same time, compared with the alcohol injection method of radiofrequency ablation, the clinical results showed that the total tumor necrosis rate of radiofrequency ablation was 90%, while the alcohol injection method was 80%. The average number of cycles of radiofrequency ablation per tumor was 1.2 versus 4.8 for alcohol injection. The effect of radiofrequency ablation is better than that of alcohol injection.
