| Summary: Amiodarone (AMD) is potent antiarrhytmic, iodine rich drug. Patiens treated with AMD are iodine overloaded. In 42 patients treated with AMD, 20 euthyroid and 22 with subclinical or clinical amiodarone induced thyroid dysfunction (TD), we have performed one or more »in vivo« thyroid tests – 99mTcO4- static scintigraphy, 99mTcO4- uptake test (TcU) and radioiodine uptake test (RAIU). In all but two euthyroid patients thyroid was »blocked«. Remaining two had functional nodes well visualised despite of iodine overload. Amiodarone induced thyrotoxicosis (AIT) showed either preserved or increased accumulation of tracer, AIT type 1, or reduced accumulation, AIT type 2. In patient with amiodarone induced hypothyroidism (AIH) and one with subclinical hypothyroidism RAIU in 3 h was normal. In subclinicly hyperthyroid patients findings varied. In 7 patients 99mTc-MIBI thyroid scintigraphy was done. 99mTc-MIBI thyroid visualization was good only in one subclinicly hypothyroid patient. 99mTcO4- scintigraphy, 99mTcO4- uptake test (TcU) and radioiodine uptake test (RAIU) of in vivo thyroid tests were useful in differential diagnosis of two types of AIT. Key words: amiodarone, 99mTcO4- tyroid scintigraphy, 99mTcO4- uptake test (TcU), radioiodine uptake test (RAIU), 99mTc-MIBI thyroid scintigraphy Napomena: kompletan tekst rada na srpskom jeziku Note: full text in Serbian |
