Not all diseases are not recommended for radiofrequency ablation, and doctors will choose whether to perform radiofrequency ablation treatment according to the patient’s own situation. Radiofrequency ablation is clinically used to treat cardiac arrhythmia and liver tumor, which has the advantages of small trauma, precise efficacy and wide indications. In addition, radiofrequency ablation can also be used to remove under-eye bags, mainly through high-frequency electric waves to heat the fat cells off the orbital septum, so that the fat cells decompose, thus eliminating the accumulation of fat in the eyelids. Doctors do not recommend radiofrequency ablation may have the following circumstances: 1. Patient’s physical condition: regardless of any disease state, doctors do not recommend radiofrequency ablation for women during pregnancy, because prolonged X-ray exposure during the procedure is harmful to both mother and child. For elderly and children patients, in addition to the above indications, it is advisable to take a conservative attitude and carefully weigh the pros and cons of using catheterized radiofrequency ablation technology; 2. Location of lesion: In patients with hepatocellular carcinoma, if the lesion is located adjacent to the hepatoportal bile duct, intraoperative or postoperative problems such as biliary tract infection, bile duct injury, biliary tract secondary stenosis and bile leakage or bile tumor may be complicated, so doctors do not recommend radiofrequency ablation. If hepatocellular carcinoma is located in the parietal tumor, because this location is the most complicated part of liver anatomy, bile ducts and blood vessels are crisscrossed, which can cause more serious complications if not careful, doctors also do not recommend RF ablation. If patients want to remove eye bags, eye skin with malignant tumor or precancerous lesions, allergic to extreme thermal stimulation, and with any active implants, such as pacemakers, artificial heart, etc. are not recommended to do radiofrequency ablation; 3. Degree of lesion: if in the advanced stage of cancer, the tumor is large and has metastasis, it is also not suitable for radiofrequency ablation.
