Plasma exchange and early thyroidectomy in thyroid storm requiring extracorporeal membrane oxygenation

Abstract

Administration of beta-blockers in thyroid storm presenting with congestive cardiac failure may precipitate cardiovascular collapse due to inhibition of thyroid-induced hyperadrenergic compensation which maintains cardiac output. TPE can be an effective bridging therapy to emergency total thyroidectomy when conventional thyroid storm treatment is contraindicated. End-organ support using ECMO and CRRT can be combined with TPE effectively in the management of critically ill cases of thyroid storm. The effectiveness of plasma exchange in lowering thyroid hormones appears to wane after 44–48 h of therapy in this case, highlighting the importance early thyroidectomy.
