Whether a patient with thyroid nodule bleeding is serious or not is objectively analyzed based on how much thyroid nodule bleeding is present and whether it is accompanied locally by trachea, esophagus, nerve compression, and other factors. First, if the patient’s thyroid nodule is small in size, the amount of bleeding is small, and there is no local trachea, esophagus or nerve compression. A small amount of bleeding can often stop on its own without causing serious complications, and the patient’s prognosis is better. Second, if the patient’s thyroid nodule is larger in size, the bleeding is more, causing obvious swelling and pain at the patient’s neck, accompanied by trachea and esophagus compression symptoms, the patient has different degrees of swallowing and breathing difficulties, at this time the patient’s condition is more serious. It is necessary to clarify the location and quantity of blood accumulation under the localization of ultrasound as soon as possible, and perform surgery to remove the local blood accumulation as soon as possible, and release the compression of trachea and esophagus, so as to avoid the occurrence of more serious complications.
