Microwave ablation, i.e. radiofrequency ablation, has disadvantages related to the organs of the surgery, such as thyroid nodule ablation may lead to laryngeal recurrent nerve injury; lung cancer ablation may lead to pneumothorax and so on. 1. Thyroid ablation: as the recurrent laryngeal nerve is close to the thyroid gland, microwave ablation of thyroid nodule may lead to damage of recurrent laryngeal nerve, resulting in hoarseness; if both recurrent laryngeal nerves are damaged, it may lead to respiratory difficulties and other serious consequences. 2. Lung cancer ablation: after lung cancer ablation, patients often have continuous pain and may need medication to maintain pain relief; in addition, serious complications such as bleeding, infection, high fever, pneumothorax and so on may occur after the operation. 3. Liver ablation: microwave ablation of hepatic malignant tumor or hepatic hemangioma may cause damage to liver bile ducts and blood vessels due to the high ablation power and long time, and even serious complications such as hemorrhage, infection and biliary fistula may occur after the operation. 4. Cardiac radiofrequency ablation: cardiac radiofrequency ablation is commonly used in the treatment of tachyarrhythmia, because the electrode is placed in the heart, the operation may cause heart rupture or perforation, pericardial effusion or even pericardial tamponade may occur during or after the operation. If necessary, it is recommended to go to a regular hospital for radiofrequency ablation and choose a surgical plan under the judgment of a professional doctor.
