彩色多普勒超声监测Graves病甲状腺动脉栓塞后血流变化的临床研究

目的 研究彩色多普勒超声在监测甲状腺动脉栓塞治疗Grayes病后甲状腺血流变化，以及对临床疗效的评估作用。方法 31例确诊Graves病的患者行甲状腺动脉栓塞治疗，其中11例用彩色多普勒超声监测治疗前后甲状腺的血流变化，观察指标有甲状腺内部血流信号、甲状腺上动脉舒张期内径、收缩期最大血流速度(Vmax)、舒张期最小血流速度(Vmin)、阻力指数(RI)和甲状腺大小。同时观察临床症状和相关的实验室检查指标的变化情况。结果 Graves病甲状腺动脉栓塞治疗后，甲状腺上动脉舒张期内径、Vmax和Vmin明显降低，甲状腺内部血流明显减少，甲状腺体积缩小。临床症状好转或消失，相关的实验室检查指标恢复正常。结论 彩色多普勒超声可用于评估甲状腺动脉栓塞治疗Grayes病的疗效，是一种较好的无创性动态监测方法。

Clinical study of color Doppler sonography in Graves' disease blood flow changes after thyroid arteries embolizaion

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.
