摘要
目的:探讨彩色多普勒超声对观察不同妊娠期甲状腺超声测量参数变化的临床价值。方法:选取以ATA指南为标准甲功正常非妊娠期妇女(对照组)53例,妊娠早期30例、中期60例及晚期妇女55例,以彩色多普勒超声检查观察并测定甲状腺大小、甲状腺上动脉内径(D)、阻力指数(RI)、舒张末期血流速度(PDV)及收缩期最大血流速度(PSV)并进行统计学分析。结果:与对照组相比,不同妊娠期甲状腺上动脉PSV差异有统计学意义,其中妊娠早期差异更为显著;不同妊娠期两两相比唯有晚期甲状腺上动脉PSV显著低于早期;不同妊娠期甲状腺上动脉PSV与甲状腺激素TSH水平呈负相关,与FT4、FT3水平呈正相关。结论:不同妊娠期妇女甲状腺大小、甲状腺上动脉PDV、D及RI与正常人群相比无明显变化。不同妊娠期甲状腺上动脉PSV较正常人群增高;妊娠晚期甲状腺上动脉血流PSV较早期下降。不同妊娠期甲状腺上动脉PSV的改变可以反映不同妊娠期TSH、FT3、FT4水平的变化。
Objective: To investigate the clinical value of color Doppler ultrasound in observing the changes of thyroid ultrasound parameters at different gestational period.Methods: Fifty-three non-pregnant women were involved as the control group,in whom the thyroid function is identified normal by the ATA guidelines.Moreover 30 women in the early gestational period,60 women in the middle gestational period,and 55 women in the late gestational period were enrolled as the study group.The thyroid size,thyroid artery diameter(D),resistance index(RI),end diastolic blood flow velocity(PDV),and systolic peak blood flow velocity(PSV) were measured with color Doppler ultrasound,statistical analysis were also performed.Results: Thyroid artery peak systolic flow velocities in different gestational period were compared with those of the control group,there were statistical difference,which increased more obviously in the early gestational period.The thyroid artery PSV was statistically lower in the late gestational period than that of the early period.The PSV and TSH levels were negatively correlated with those of different gestational period,and positively correlated with FT4,FT3 levels.Conclusion: There are no significant changes in thyroid size,thyroid artery D,and RI in different gestational period compared with those of the control group.In different gestational group,PSV is higher than that of the control group.In the late period,the PSV is lower than that in the early period.In different gestational period the increase of PSV correlated iwth FT4 and FT3.
