通过测定Graves病（GD）未治组17例及缓解期组9例患者的甲状腺上、下动脉峰值血流速度（PFV），发现两组患者甲状腺上、下动脉的PFV均明显高于对照组；两组之间甲状腺上动脉的PFV有显著差异，但甲状腺下动脉的PFV无差异性。提示：（1）甲状腺PFV的恢复晚于甲状腺功能的恢复，或甲状腺血流状态不仅取决于甲状腺功能状态；（2）GD的药物治疗不应短于12个月；（3）甲状腺下动脉PFV恢复较慢，对GD的预后有一定意义。

17 cases of untreated and 13 cases of remitted patients with graves disease (GD) were examined by color Doppler ultrasound. The results showed tha the peak flowing velocity (PFV) of the superior thyroid artery of two groups are both significanily higher than that of the control. The difference of PFV of the superior thyroid ariery between the two groups was marked , while it was not significant for the inferior thyroid artery. This indicated that (1) The PFV of thyroid arteries revcovered slower than that of thyroid function . (2) More than 12 months of treatment would be necessary to obtain remission of PFV of thyroid arteries. (3) The PFV of thyroid arteries espeially of the inferio thyroid artery are useful indices to discontinue antithyroid drugs .
