不同年龄结节性甲状腺肿合并甲状腺癌患者甲状腺超声特征对比分析

Contrastive Analysis of Thyroid Ultrasonography in Patients with Nodular Goiter and Thyroid Carcinoma

目的:分析不同年龄结节性甲状腺肿合并甲状腺癌患者甲状腺超声特征。方法:选取2016年1月-2017年6月50例医院收治结节性甲状腺肿合并甲状腺癌患者作为观察对象,根据患者的年龄分为青年组(20~40岁)、中年组(41~60岁)和老年组(> 60岁)。所有患者均行甲状腺超声和多普勒超声检查。比较三组患者甲状腺超声特征,主要包括回声、平均收缩期流速、钙化、Ⅲ型血流比例、阻力指数等指标。结果:青年组在粗钙化病灶率、微小钙化病灶率、低回声率、病灶Ⅲ型血流比例、平均收缩期流速、阻力指数等数值明显高于中年组和老年组(P <0. 05),而中年组在上述指标方面均明显高于老年组(P <0. 05);老年组在无钙化病灶率和无回声率方面明显高于青年组和中年组(P <0. 05),且青年组在无钙化病灶率方面明显低于中年组(P <0. 05)。结论:不同年龄段结节性甲状腺肿合并甲状腺癌患者的甲状腺超声特征均有不同之处,青年患者的超声特征主要为粗钙化病灶、微小钙化病灶、低回声、平均收缩期流速和阻力指数高,老年患者的超声特征为无钙化病灶和无回声。

Objective: to analyze thyroid ultrasonography in patients with different age of tuberous goiter and thyroid carcinoma. Selection methods: January 2016-June 2017 50 cases of hospital patients with nodular goiter with thyroid carcinoma underwent as research object,according to the age of the patients are divided into young(20 ~ 40),middle-aged(41 ~ 60 years old) and elderly group(> 60 years). All patients underwent thyroid ultrasound and doppler ultrasonography. Comparison of three groups of patients with thyroid ultrasound characteristics,mainly including the echo,calcification,Ⅲ blood flow,average systolic velocity ratio and resistance index. Results: the rate of youth in the coarse calcification lesions,tiny calcified lesions rate,low rate of the echo,lesion type Ⅲ ratio,average systolic blood flow velocity,resistance index such as numerical significantly higher than that of middle-aged and elderly group(P < 0. 05),while in the above indicators middle age group were significantly higher than the elderly group(P < 0. 05); In the elderly group,there were significantly higher rates of non-calcified lesions and anechoic rates than those in the youth group and middle age group(P < 0. 05),and the youth group was significantly lower than the middle-aged group(P < 0. 05) in the non-calcified lesions. Conclusion: different age patients with nodular goiter with thyroid carcinoma of thyroid ultrasonic characteristics are different,the sonographic features of young patients are mainly coarse calcification lesions,tiny calcified lesions,low echo,average systolic velocity and resistance index is high,the sonographic features of elderly patients with calcified lesions and without echo.
