Abstract:
Objective:To analyze the predictive value of ultrasound blood flow parameters for postoperative cervical lymph node metastasis in thyroid cancer.Methods:Fifty-three patients with thyroid cancer who received medical treatment in Guang′anmen Hospital of China Academy of Chinese Medical Sciences from August 2020 to December 2022 were selected as the observation group, and 53 healthy patients who received physical examination in the physical examination center during the same period were selected as the healthy group. All of them were given ultrasound examination. The ultrasonic blood flow parameters including peak systolic flow velocity (PSV), pulsation index (PI), resistance index (RI) of the two groups were compared. The patients with thyroid cancer were divided into metastatic group (33 cases) and non-metastatic group (20 cases) according to the presence or absence of lymph node metastasis. The ultrasonic blood flow parameters, blood flow grading and ultrasonographic characteristics of the two groups were compared.Results:The levels of PSV in the observation group was higher than that in the health group, PI and RI were lower than those in the health group: (25.56 ± 5.25) cm/s vs. (14.52 ± 2.85) cm/s, 0.51 ± 0.13 vs. 0.63 ± 0.16, 0.82 ± 0.11 vs. 1.15 ± 0.24, there were statistical differences ( P<0.05). The levels of PSV in the metastatic group was higher than that in non-metastatic group, PI and RI were lower than those in the non-metastatic group: (29.65 ± 3.76) cm/s vs. (19.20 ± 2.96) cm/s, 0.48 ± 0.10 vs. 0.56 ± 0.05, 0.76 ± 0.13 vs. 0.91 ± 0.19, there were statistical differences ( P<0.05). The blood grade between the metastatic group and non-metastatic group had statistical difference ( P<0.05). The rates of blood flow signal disjointed, blood flow abundant, micro-calcification boundary unclear, internal echo uneven and the length-width ratio <2 in the metastatic group were higher than those in the non-metastatic group: 54.55%(18/33) vs. 25.00%(5/20), 78.79%(26/33) vs. 50.00%(10/20), 57.58%(19/33) vs. 20.00%(4/20), 66.67%(22/33) vs. 35.00%(7/20), 63.64%(21/33) vs. 30.00%(6/20), 63.64%(21/33) vs. 25.00%(5/20), there were statistical differences ( P<0.05). Conclusions:Abnormal ultrasonic blood flow parameters in patients with thyroid cancer are closely related to lymph node metastasis. Quantitative detection of ultrasonic blood flow parameters can provide a reliable reference for the evaluation of thyroid cancer.
