In recent years, interventional therapy technology has become more mature and has been widely used in clinics. Radio-frequency ablation is one of the interventional therapies. It has been applied in various benign and malignant solid tumors such as liver cancer, breast cancer, uterine fibroids, and paroxysmal supraventricular tachycardia, including atrioventricular nodal reentrant tachycardia and atrioventricular reentrant tachycardia with great effect. But many patients may worry about whether this radiation method will have adverse effects on the body. Is this worry necessary?
Under the guidance of imaging equipment, Radio-frequency ablation uses an electrode catheter to insert into the lesion and then releases a radiofrequency current to produce a thermal effect, which acts on the diseased cells to cause coagulative necrosis, so as to achieve the purpose of treatment. The safety factor of this therapy is relatively high in general. First of all, its essence is a minimally invasive therapy, which does not need to operate to expose the focus with general anesthesia like the traditional surgical therapy, so it greatly reduces the treatment risk. In addition, although the released RF current is a radio frequency, it does not belong to the division of bands in radio communication. In such a frequency range, the radiation performance is very low, and the scope of action has certain limitations which will not cause radiation harm to the human body. Patients need not worry too much about this.
However, any therapy has certain risks, and Radio-frequency ablation is no exception. Although Radio-frequency ablation has few side effects, there are still side effects after operation. In the treatment of liver cancer, there may be discomfort reactions such as fever, nausea, and vomiting after the operation, which are mostly caused by the absorption of dead tumor tissue by the body. Most patients can recover by themselves. In severe cases, the doctor shall be informed in time for relevant cooling and antiemetic treatment. For Radio-frequency ablation of the heart, it may be complicated by bleeding, hematoma, infection, pneumothorax, thrombosis, embolism, and so on. Complications of catheterization include aortic regurgitation, myocardial perforation, pericardial tamponade, and so on.
Overall, Radio-frequency ablation has a high success rate and fewer side effects. As long as we pay attention to relevant nursing after the operation, including wound, diet, and psychological nursing, the prognosis will be generally good. Patients can choose to use it under the evaluation and guidance of doctors to ensure the curative effect.
