Massive Hemorrhage and Mortality Following Thyroid Radiofrequency Ablation.

Radiofrequency ablation (RFA) provides a relatively safe and noninvasive option for treating benign thyroid nodules and thyroid cancer that is cosmetically superior to surgery. Following a loss of consciousness 1 h after thyroid RFA, a 56-year-old patient was transferred to the emergency room. Despite undergoing coronary angiography due to 3 cardiac arrests, the results were normal. Although brain, chest, and abdominal computed tomography scans were performed, the emergency physician failed to detect any hematoma formation. Despite the use of mechanical ventilation and extracorporeal membrane oxygenation, the patient exhibited persistent hypoventilation. It was later discovered that an aggravated massive hemorrhage had occurred, due to which inferior thyroid artery embolization and surgical hematoma evacuation were performed. Unfortunately, prolonged brain hypoperfusion resulting from airway compromise and common carotid artery occlusion resulted in brain death and, ultimately, the patient's demise. In conclusion, massive hemorrhages caused by RFA require immediate diagnosis and hemostasis.
