title: [Role of color Doppler in the evaluation of the hyperfunctioning thyroid nodule treated with ethanol injection].
abstract: Color Doppler gives us the possibility to study autonomous thyroid nodules and their qualitative and morphological aspects and allows us to hit session by session the most vascular area of the nodule with alcohol (Percutaneous ethanol injection). The use of color gives an easier flowmeter analysis reducing its time of performance. Today this method with the latest up to date echographs can provide very good clinical pathology at relatively low costs. We studied 18 patients, with autonomous thyroid nodules. They were all treated by percutaneous echo-guided ethanol injection (PEI). Before the beginning we make sure that the rest of the thyroid gland may function normally. The color Doppler test was carried out by using the multidisciplinary ecotomograph AU 560 CFM supplied with a linear probe 7.5 mHz, AL 35 by Esaote Biomedica. Before the PEI treatment, with the eco color Doppler test we noticed that the hot nodules clearly presented a higher vascularization compared to the remaining parenchyma. The vascularization was more evident in the peripheral area of the nodule even if few signs of flow were present inside the nodule. During a 24 months followup, 10 patients showed an important reduction and sometimes even the extinction of the intranodular flow signs followed by a clear reduction of the nodule's volume.
