[Regional hemodynamic changes in nodular goiter]

The goal of the present study was to evaluate the clinical and diagnostic value of regional hemodynamic changes in the thyroid vessels and carotid beds in patients with different forms of nodular goiter in order to optimize further follow-up and treatment. The study covered 120patients aged 25 to 40years (mean age 32.82±0.36 years) who had nodular goiter. A control group comprised 30 women comparable by age (mean age 32. 06±0. 44 years), who had a morphologically and functionally unchanged thyroid. After examined, the patients with nodular goiter were divided into group according to the identified morphological forms. Group 1 consisted of25 (20.8%) women (mean age 34.85±0.89 years) with signs of nodular malignancies; Group 2 included 35 (29.2%) patients (mean age 32.08±0.78years) with detected adenomas; Group 3 comprised 40 (33.3%) patients (mean age 33.6±1.08years) with colloidal nodules, and Group consisted 20 (16.7%) women (mean age 32.87±0.9 years) with signs of cysts. The study and comparison of the linear and volume parameters of arterial ducts to the euthyroid loves in nodular pathology were made, by taking into account the site of an abnormal focus and its morphological structure. The linear and volumetric bloodflow rates in the thyroid arteries ipsilaterally to the abnormal nodular of any morphological structure were found to be significantly higher (p < 0.05). Changes were revealed in blood flow parameters in the carotid bed in relation to the morphological structure of nodules.
