The basilic vein as an in situ bypass for occlusion of the brachial artery

For 30 years we have followed the case of a euthyroid patient who had a goiter diagnosed at age 15. It was originally diffuse and did not shrink during treatment, first with desiccated thyroid extract and then with triiodothyronine. After treatment was stopped, the goiter gradually became nodular and calcified when the patient was in her late teens or early 20s; it then shrank. She remains clinically and chemically euthyroid, with a calcified, multinodular goiter and persistent elevation of the serum PBI concentration which, early in the course of the disease was shown to include a substantial fraction of butanol-insoluble iodine. In a euthyroid patient, the association of an elevated serum PBI concentration (with an abnormally large butanol-insoluble iodine fraction) with a diffuse goiter that became nodular and calcified may be unique.
