| ［摘要］目的 探讨超声检测气管旁淋巴结对自身免疫甲状腺炎（autoimmune thyroiditis，AIT）的诊断价值．方法 选取101例AIT患者，同期选取毒性弥漫性甲状腺肿患者（Graves’disease，GD）35例为GD组、亚急性甲状腺炎患者（subacute thyroiditis，SAT）31例为SAT组、正常人群60例为对照组，进行实验室检查（TSH、TGAb、TPOAb），观察甲状腺二维超声表现及彩色多普勒血流特征；同时观察气管旁两侧淋巴结是否显示及显示淋巴结纵横比、皮髓质分界及彩色多普勒血流特征．结果 AIT组、GD组、SAT组在实验室检测指标（TSH、TPOAB、TGAB）方面差异有统计学意义（P＜0.05）；AIT组、GD组、SAT组和正常组在气管旁淋巴结显示率、气管旁淋巴结数目、淋巴结纵径、淋巴结横径、淋巴结纵横比、彩色多普勒血流等方面存在统计学差异（P＜0.05），皮髓质分界未见统计学差异（P＞0.05）．结论 超声检测气管旁淋巴结对自身免疫甲状腺炎鉴别诊断有一定价值，可以辅助判断弥漫性甲状腺病变的性质． |

| Abstract: |
| ［Abstract］Objective To investigate the value of detecting the paratracheal lymph nodes by ultrasound in diagnosis of autoimmune thyroiditis （AIT）. Methods We selected 101 AIT cases as experimental group. At the same period，35 cases of Graves'disease（GD），31 cases of subacute thyroiditis（SAT），and 60 normal cases were selected as control groups. Lab tests，such as TSH，TGAb，and TPOAb were carried out and the morphology of thyroid，characteristics of two dimensional ultrasound， and colorful Doppler flow were observed. Meanwhile， whether displayed the paratracheal lymph node or not，the aspect ratio of the displayed paratracheal lymph node， corticomedullary differentiation，and the characteristics of colorful blood flow were observed. Results There were significant difference in lab test indicators （TSH， TPOAB，TGAB） among AIT group，GD group，and SAT group（P＜0.05）. There were significant differences in displayed rate of paratracheal lymph node， number of paratracheal lymph node， aspect ratio of the displayed paratracheal lymph node and colorful Doppler flow among AIT group， GD group， SAT group， and normal group（P＜0.05）， but the indicator of corticomedullary differentiation had no significant difference（P＞0.05）. Conclusion Ultrasound examination of the paratracheal lymph node has the diagnostic value in diagnosis of autoimmune thyroiditis，and may assist us to judge the nature of diffused thyroid diseases. |
