摘　　要：目的:应用彩色多普勒超声评估甲状腺功能亢进(简称甲亢)患者术前碘准备期间甲状腺体积和血流的变化。方法:86例因甲亢行甲状腺手术切除患者在服碘前1 d、服碘后第7、14天行彩色多普勒超声检查,比较服碘前后甲状腺体积、甲状腺上动脉收缩期峰值血流速度(PSV)、舒张末期血流速度(EDV)、RI有无差异,分析甲状腺实质内血流分级变化。结果:服碘后,甲状腺体积逐渐缩小,服碘后第14天与服碘前1 d相比差异有统计学意义(P<0.05);服碘后甲状腺上动脉的PSV、EDV均较服碘前明显降低(均P<0.05);服碘前1 d甲状腺实质内血流分级以3级为主,占76.74%(66/86),服碘7 d后降至26.74%(23/86),服碘第14天降至7.00%(6/86)。结论:甲亢患者术前碘准备期间,甲状腺体积持续缩小,血流明显减少,彩色多普勒超声可准确评估甲状腺的体积和血流变化。Objective:To evaluate the thyroid volume and blood flow in patients with hyperthyroidism during pre-operation iodine preparation by color Doppler ultrasound.Methods:Color Doppler ultrasound examination was performed on 86 patients with hyperthyroidism one day before taking iodine,7 days and 14 days after taking iodine.The thyroid volume,peak systolic velocity(PSV),end-diastolic velocity(EDV)and RI of superior thyroid artery during iodine preparation were compared,and the grading changes of blood flow in thyroid parenchyma was analysed.Results:After taking iodine,the volume of thyroid decreased,and the difference was statistically significant between the 14th day after taking iodine and one day before taking iodine(P<0.05).The PSV,EDV of the superior thyroid artery after taking iodine was significantly lower than that before taking iodine,and the differences among groups were statistically significant(all P<0.05).The blood flow in thyroid gland was mainly classified as grade 3 one day before iodine administration,accounting for 76.74%(66/86).After 7 days of taking iodine,the ratio of grade 3 blood flow in patients dropped to 26.74%(23/86),and the proportion on the 14th day further reduced to 7.00%(6/86).Conclusions:The volume of thyroid decreases and the blood flow decreases significantly during the preparation of iodine in patients with hyperthyroidism before operation.Color Doppler ultrasound can accurately evaluate the volume and blood flow of thyroid.
