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

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.
