目的：探讨利用超声血流动力学诊断甲状腺乳头状癌（ PTC）颈部淋巴结转移的临床价值。方法回顾性分析132例甲状腺乳头状癌患者的临床资料，记录超声检测淋巴结的纵横比、内部回声、均匀性、边界规则性和钙化情况。分析淋巴结转移组和无转移组（对照组）的差异。结果超声血流动力学诊断甲状腺乳头状癌颈部淋巴结转移的灵敏度分别为纵横比﹤2（93.06%）、淋巴结内部回声（94.44%）、边界（90.28%）、钙化情况（87.50%）；淋巴结转移组与对照组的纵横比、淋巴结内部回声、边界、钙化情况的差异有统计学意义（χ2＝88.009、78.895、48.584、66.429，P均＝0.000）。结论超声血流动力学检查是诊断甲状腺乳头状癌颈部淋巴结转移的一种高效、快速方便的方法，有重要临床参考价值。%Objective To study the clinical value of ultrasonic hemodynamics in the diagnosis of neck lymph node metastasis of papillary thyroid carcinoma( PTC). Methods Retrospectively analyzed the clinical data of 132 patients with PTC,the aspect ratio of the lymph nodes,inter-nal echo,uniformity,border rules and calcification by ultrasonic testing were recorded. Results The sensitivity of ultrasonic blood flow dynamics for the diagnosis of neck lymph node metastasis of PTC were respectively aspect ratio ﹤2(93. 06%),internal echoes of lymph nodes(94. 44%), boundary(90. 28%),and calcification(87. 50%). There were statistically significant differences in the aspect ratio,internal echo,boundary,and calcification of the lymph nodes between lymph node metastasis group and control group(χ2 =88. 009,78. 895,48. 584,66. 429,respectively all P=0. 000). Conclusion Ultrasound hemodynamic examination is highly efficient,rapid and convenient method for the diagnosis of cervical lymph node metastasis of PTC.
