彩色多普勒超声在颈部淋巴结结核诊断中的应用

Application of color Doppler ultrasound in diagnosis of cervical lymph node tuberculosis

目的分析彩色多普勒超声在颈部淋巴结结核诊断中的应用。方法回顾性分析2015年1月~2016年5月本院收治的114例颈部淋巴结肿大患者的临床资料,根据彩色多普勒超声诊断结果分为结核性淋巴结组(n=45)和非结核性淋巴结组(n=69)。分析两组患者的诊断特征,对比两组患者CDFI参数,分析两组患者病变类型与血流分型的关系。结果 45例结核性淋巴结组患者中,结核性淋巴结45个;69例非结核性淋巴结组患者中,淋巴结78个,其中转移性淋巴结28个,炎性淋巴结35个,淋巴瘤15个。结核性淋巴结组患者的L/S值低于非结核性淋巴结组患者,Vmax高于非结核性淋巴结组患者,比较差异均有统计学意义(P<0.05)。两组患者PI和RI比较差异无统计学意义。结核性淋巴结组患者的边缘型和淋巴门+边缘混合型血流分型比例均显著低于非结核性淋巴结组患者,差异具有统计学意义(P<0.05)。结论彩色多普勒超声可清晰诊断颈部淋巴结结核病变,提高颈部淋巴结结核临床诊断效果,值得应用。

Objective To analyze the application of color Doppler ultrasound in the diagnosis of cervical lymph node tuberculosis. Methods A retrospective analysis of the clinical data of 114 patients with cervical lymphadenopathy from January 2015 to May 2016 in our hospital, according to the results of color Doppler ultrasound, were divided into tuberculous lymph nodes （n=45） and non tuberculous lymph node （n=69）. The diagnostic features of the two groups were analyzed, and the CDFI parameters of the two groups were compared, and the relationship between the types of the lesions and the blood flow- pattern in the two groups was analyzed. Results In 45 patients with tuberculous lymph nodes, there were 45 tuberculous lymph node. Among 69 patients with non-tuberculous lymph nodes, there were 78 lymph node, including 28 metastatic lymph nodes, 35 inflammato- ry lymph nodes, and 15 lymphoma. The L/S value of the tuberculous lymph nodes group was lower than that of the non-tuberculous lymph nodes group, the Vmax was higher than that of non-tuberculous lymph nodes group, the difference was statistically significant （P〈0.05）. There was no sig-nificant difference in PI and RI between the two groups. The proportion of marginal and lymphatic portal ＋ marginal mixed blood flow classification in tuberculous lymph node group was significantly lower than that in non-tuberculous lymph node group. The difference was statistically significant （P〈0.05）. Conclusion Color Doppler ultrasound can clearly diagnose the tuberculosis of neck lymph node and improve the clinical diagnosis effect of cervical lymph node tuberculosis. It is worthy of application.
