Filtering the blood to make thyroid surgery safe in amiodarone thyrotoxicosis
When drugs failed to control amiodarone-induced thyrotoxicosis and arrhythmias persisted, clinicians used plasma exchange to prepare a patient for thyroid removal.
A man in his mid-60s with severe cardiomyopathy and recurrent ventricular tachycardia developed thyrotoxicosis after exposure to amiodarone. His disease showed features of both type 1 and type 2 amiodarone-induced thyrotoxicosis, which made the diagnosis difficult.
High-dose thionamides and glucocorticoids, plus lithium and cholestyramine, did not control the thyroid overactivity. Life-threatening arrhythmias continued. Surgery was the definitive option, but operating on a thyrotoxic patient with a weak heart carries substantial risk.
The team used therapeutic plasma exchange as a bridge, aiming for rapid biochemical improvement before total thyroidectomy and lower perioperative risk. The authors present this as a strategy worth considering through multidisciplinary care.
This is a report of a single patient, so it cannot show how well plasma exchange works or how often it is safe in this setting.
