Clinical study of color Doppler sonography in Graves' disease blood flow changes after thyroid arteries embolizaion / 介入放射学杂志

ABSTRACT

Objective To study the color doppler image characteristics of thyroid arteries pre and post interventional procedure and to assess the clinical efficacy in Gnaves' disease.Methods 11 from 31 patients diagnosed as Graves' disease undertaken thyroid arteries embolization, were analyzed. Color Doppler sonography was applied to monitor the pre and post procedure thyroid size and diameters of thyroid arteries. Power Doppler was used to detect the Vmax, Vmin, RI and blood flow. Results After thyroid arteries embolization, the size and vascularity of thyroids were reduced. The thyroid arteries showed shrinkage and stoppage blood flow at the embolized site. The changes of RI, blood parameters of Vmax, Vmin and diameters of the thyroid arteries pre and post procedure turned out to be statistically significant for clinical restriction.Conclusion The color Doppler sonography plays an important role for preoperative diagnosis and predicting the prognosis.
