Microwave ablation surgery tends to vary according to the organ operated on, and the post-operative drawbacks also tend to vary. First, if it is a thyroid nodule, microwave ablation surgery is performed. After the surgery, it may cause damage to the recurrent laryngeal nerve and cause hoarseness in the patient. If both sides of the recurrent laryngeal nerve are damaged, the patient may have serious complications such as breathing difficulties. Second, if the thyroid nodules in the microwave ablation treatment process is more powerful, it may cause damage to the blood supply of the parathyroid glands or damage to the parathyroid glands. At this time, patients will have numbness in the corners of the mouth and limbs, and even have persistent convulsions, muscle spasms and other manifestations of hypocalcemia. Third, liver hemangioma or liver malignant tumor in the microwave treatment, if the intraoperative power is high and the ablation time is too long, it will cause damage to portal vein, hepatic artery and intrahepatic bile duct. Postoperatively, patients develop localized biliary fistula, bleeding and other serious complications.
