title: Serum triiodothyronine and reverse triiodothyronine concentrations after surgical operation.
abstract: Serum-triiodothyronine (T3) concentrations fell rapidly after surgery in six out of seven initially euthyroid patients. Simultaneous increases in reverse triiodothyronine (rT3) concentrations suggested that the peripheral monodeiodination of thyroxine (T4) proceeds by an alternative pathway in the postoperative period.
