摘要
目的 :研究鼻咽癌颈转移淋巴结的彩色多普勒血流信号特征。材料与方法 :鼻咽癌伴颈淋巴结转移患者 5 2例共 134枚颈转移淋巴结 ,在接受治疗前行彩色多普勒血流检查 ,分析其血流信号特征和血供强度与淋巴结大小、部位的关系。结果 :鼻咽癌颈转移淋巴结的动脉血管多分布在淋巴结的周边 ,血流阻抗 (RI)高 ;淋巴结血流强度的分布因淋巴结部位、大小的变化而不同 ,大淋巴结较小淋巴结血供丰富 ;中、下颈淋巴结较上颈淋巴结血供丰富。结论 :鼻咽癌颈转移淋巴结以周边型高阻血流信号为主。血供强度与淋巴结大小。
Purpose: To study the characteristics of Color Doppler flow signal in cervical lymph nodes with metastasis from nasopharyngeal carcinoma. Materals and Methods: 134 cervical lymph nodes metastasis from nasopharyngeal carcinoma in 52 patients were examined by color Doppler flow before treatment. The characteristics of blood flow signal and the relationship between blood supply and the volume and location of lymph nodes were analysed. Results: The blood vessels of the cervical lymph nodes of nasopharyngeal carcinoma metastasis were mainly located in the peripheral, and the RI value was high; The distribution of lymph nodes blood flow intensity varied with the location and the volume of lymph nodes (P<0 01). The blood supply of big lymph node was more abundant than that of small one; the blood supplies of lymph node at middle and of low cervical region were more than that at upper part. Conclusion: The blood flow signal of peripheral pattern and with high RI mainly account for cervical lymph nodes metastasis from nasopharyngeal carcinoma. The intensity of blood supply correlated with the volume and location of lymph nodes.
