Abstract:
During thyroid surgery, intraoperative hemodynamic instability can be attributed to episodic surges of thyroid hormones. Thyroid storms are emergency situations characterized by persistent hypertension, tachycardia, hyperthermia, and end-organ damage. However, baroreflex-mediated neurogenic phenomena due to surgical procedures near the carotid sinus are a likely cause of acute hemodynamic changes during thyroid surgery. We describe a case of sudden hemodynamic instability occurring after thyroid manipulation during thyroidectomy in a 61-year-old man who presented with a 6-cm-sized thyroid mass in a euthyroid state.
