目的探讨彩色多普勒超声在甲状腺功能亢进症中应用价值。方法将120例原发性甲亢患者按实验室检查指标和临床症状分为轻度40例;中度50例;重度30例。另选同期甲状腺功能正常者50例做为对照组。常规超声观察,甲状腺声像图特点并测量甲状腺右叶上动脉直径。彩色多普勒(CDFI)观察甲状腺内和甲状腺右叶上动脉血流分布情况,应用彩色多普勒和脉冲多普勒技术测量右叶上动脉部分血流参数。结果甲亢患者多数声像图改变(2DE):甲状腺普遍性肿大(包括峡部)以两叶对称性增大为主,边缘多规则,内部回声为密集细小的点状强回声,呈低、中等增粗增强,分布均匀或不均匀。CDFI:显示甲状腺腺体内血流信号呈弥漫性分布,呈“火海症”甲状腺右叶上动脉管径,收缩期最高流速及平均流速的变化,与对照组比较差异有统计学意义。(P<0.05)。结论常规超声和CDFI能准确测量甲亢患者甲状腺右叶上动脉的管径和收缩期最高流速,为临床诊断提供客观依据有一定的实用价值。
Objective To investigate the value of color Doppler ultrasound in hyperthyroidism. Methods 120 patients with primary hyperthyroidism according to laboratory tests and clinical symptoms were divided into mild in 40 cases; moderate in 50 cases; severe in 30 cases. Another 50 cases of normal thyroid function in the same period as a control group. Conventional ultrasonography, thyroid sonography features and measuring the diameter of the superior thyroid artery. Color Doppler (CDFI) was used to observe the distribution of arterial blood flow in the thyroid and the right lobe of the thyroid. Color Doppler and pulsed Doppler were used to measure the blood flow parameters in the right upper lobe. Results The majority of patients with hyperthyroidism changes the sound image (2DE): the general enlargement of the thyroid gland (including the isthmus) to the symmetry of the two leaves to increase the main edge of more rules, the internal echo is dense small punctate echoes, showed low, moderate Increased thickening, uniform or uneven distribution. CDFI: showed diffuse distribution of blood flow signals in the thyroid gland, was “” sea of fire "thyroid artery diameter of the right lobe, systolic peak velocity and mean velocity changes, compared with the control group, the difference was statistically significant. (P <0.05). Conclusion Conventional ultrasound and CDFI can accurately measure the diameter of the right superior thyroid artery and the maximum systolic velocity in patients with hyperthyroidism, which may provide some objective evidences for clinical diagnosis.
