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.
Aim
The aim of this case series was to assess for any indicators as to when these patients should be referred for total thyroidectomies and the efficacy of this method of treatment.
Materials and methods
A case series of patients with AIT treated with a total thyroidectomy from 1998 to 2015 was used to assess the efficacy of and indicators for surgery.
Results
Total thyroidectomy results in efficient and significant improvement in the patient's biochemistry and symptoms. The patient's symptoms and options for medical therapy have an influence on the duration of the trial of medical therapy.
Conclusion
Surgery is an effective and efficient treatment for AIT. However, there does not appear to be a specific indicator for when this treatment should be instigated. A case-by-case approach should be adopted when treating these complicated patients.
Clinical significance
Clinicians should see surgery as an effective and efficient treatment for AIT. The timing of surgery should be assessed on a case-by-case basis considering the patient's clinical status and therapeutic options and not as a last resort.
