多普勒超声对甲状腺癌病人血流动力学指标评估及与淋巴结转移的相关性分析

Evaluation of hemodynamic indexes and correlation with lymph node metastasis in patients with thyroid carcinoma by Doppler ultrasound

摘要

摘要:
目的分析甲状腺癌病人采用多普勒超声进行血流动力学指标评估效果及相应指标与淋巴结转移的相关性。
方法选取甲状腺癌病人68例作为观察组，同期随机选取门诊体检的健康人40名作为对照组。对病人进行多普勒超声检查和血流动力学指标检测评估，同时检测病人的淋巴结肿大情况，并分析其相关性。
结果观察组患侧甲状腺部位的动脉收缩期峰值、血流速度（PSV）和舒张末期血流速度均明显高于观察组健侧和对照组（P<0.01），而搏动指数、血液血流阻力指数（RI）则明显低于观察组健侧和对照组（P<0.01）；有淋巴结转移病人的PSV、RI和血流信号分级均明显高于无淋巴结转移甲状腺癌病人（P<0.01）。
结论在甲状腺癌病人多普勒超声诊断中显示血流动力学指标与淋巴结转移密切相关，也是术前评估甲状腺癌的重要参考指标。

Abstract:
ObjectiveTo investigate the correlation between hemodynamic indexes and lymph node metastasis in patients with thyroid cancer using Doppler ultrasound.
MethodsA total of 68 patients with thyroid cancer were selected as the observation group.The healthy subjects from the outpatient clinic were randomly selected as the control group.Doppler ultrasound was performed to evaluate the hemodynamic indexes, and the lymph node enlargement was detected and correlation analysis was performed.
ResultsThe systolic peak value, peak systolic velocity(PSV) and the end-diastolic blood flow velocity of the affected side in the observation group were significantly higher than those in the healthy side and the control group, while the pulsation index and blood flow resistance index(RI) were lower than those in the healthy side and the control group(P<0.01).The PSV, RI and blood flow signal grades of patients with lymph node metastasis were higher than those of patients without lymph node metastasis(P<0.01).
ConclusionsDoppler ultrasound diagnosis of thyroid cancer patients shows that hemodynamic indexes are closely related to lymph node.metastasis, and it is also an important reference index for preoperative evaluation of thyroid cancer.
