Thyroid puncture is not recommended when the ultrasound TI-RADS classification suggests a high probability of benign nodules, abnormal coagulation, myocardial infarction or stroke is not effectively controlled, etc. Individuals are different, so it is recommended to consult with your doctor for more details. Fine needle aspiration biopsy is a commonly used test for thyroid nodules, which can clarify the benign or malignant nature of the nodule. If the ultrasound TI-RADS classification is low, suggesting that the nodule is likely to be benign, puncture is not recommended, and regular follow-up observation is sufficient. If there is cardiac insufficiency or respiratory disease that prevents the patient from lying down, any condition that prevents cooperation such as a history of mental illness, abnormal coagulation function, the presence of myocardial infarction, stroke and other uncontrolled emergencies, and the presence of uncontrolled infection in the skin at the site of the thyroid puncture, puncture is not recommended or it is recommended that puncture is withheld. Thyroid nodules should be seen promptly after discovery, and related tests need to be performed under the supervision of a doctor.
