Efficacy of the Surgical Management of Amiodarone-induced Thyrotoxicosis

Abstract

Introduction: Amiodarone can be a life-saving medication; however, it can also cause amiodarone-induced thyrotoxicosis (AIT). Though rare, AIT is a complex and life-threatening side effect, which can cause significant cardiac dysfunction and lead to cardiac failure. Primary treatment is with thionamides, perchlorates, and steroids. However, a small subgroup does not respond and their cardiovascular function continues to deteriorate. This select group is referred for a semi-elective total thyroidectomy. Without surgical removal of their thyroid gland, these patients will continue to deteriorate, with a 30 to 50% mortality rate for those not operated on.
