With the development of modern minimally invasive technology, radiofrequency ablation technology has gradually improved and matured. Through online or offline science popularization, the general public's understanding and acceptance of radiofrequency ablation technology are increasing day by day. Compared with traditional surgical treatment plans, radiofrequency ablation technology has a smaller trauma surface, faster patient recovery, and significant clinical treatment effects. At present, the frequency of application of radiofrequency ablation technology in the treatment of solid tumors, gynecological diseases, cardiovascular diseases, and other clinical conditions has been increasing year by year. In clinical practice, radiofrequency ablation can also be applied to thyroid diseases such as thyroid nodules and benign thyroid tumors. So, some people may have questions about what is thyroid radiofrequency ablation therapy? How should thyroid radiofrequency ablation be performed in clinical practice?
Firstly, we can have a brief understanding of thyroid radiofrequency ablation technology. The basic therapeutic mechanism of radiofrequency ablation technology is thermal effect. When the high-frequency current emitted by the machine passes through human tissue, the rapid changes in electromagnetic field cause water molecules in human cells to move at high speed and generate heat energy. The radiofrequency ablation treatment equipment contains electrode needles that can directly contact human tissue to conduct high-frequency currents. When there are specific organic lesions in some parts of the patient's thyroid tissue, such as benign thyroid tumors, radiofrequency needles can be accurately inserted into the center of the thyroid lesion. By radiating high-frequency currents above 200 nuclear magnetic resonance, the diseased tissue heats up, dries up, and even falls off, ultimately achieving the goal of inactivating the diseased tissue.
Before treatment, patients should go to the hospital for evaluation and adjust the treatment plan under the guidance of the attending physician. Not all patients with thyroid solid lesions are suitable for thyroid radiofrequency ablation treatment. So, which thyroid related diseases can be treated with radiofrequency ablation? Firstly, patients need to complete imaging examinations such as thyroid ultrasound and magnetic resonance imaging, and if necessary, combine with biopsy of thyroid pathological tissue to rule out the possibility of malignant thyroid lesions. At the same time, the patient's thyroid disease has certain clinical symptoms, such as short-term tissue enlargement of the thyroid gland, accompanied by pain, difficulty swallowing, etc., and the patient's treatment with internal medicine drugs is not very effective. If hyperthyroidism is caused by thyroid adenoma, the patient is at high risk of thyroid crisis. Early surgical treatment is recommended, and thyroid radiofrequency ablation treatment may be considered.
However, patients need to understand that not all thyroid diseases can be treated with radiofrequency ablation. For example, if the volume of thyroid nodules is too large and the transverse diameter is greater than 7 centimeters, radiofrequency ablation treatment is not recommended. At the same time, radiofrequency ablation is also ineffective for patients with malignant thyroid tumors and multiple distant metastases. It is recommended to perform malignant tumor resection surgery as soon as possible. If the patient has serious cardiovascular disease, diabetes and is over 75 years old, it is necessary to fully understand the risk of surgery before radiofrequency ablation treatment.
