摘要
目的 评价彩色多普勒血流成像及血流动力学在颌面颈部淋巴结核诊断中的应用价值及其病理学基础。方法选取1998年1月～2003年12月在天津医科大学总医院住院的颌面及颈部淋巴结肿大患者184例，对其中224个淋巴结在术前进行彩色多普勒超声检查。记录淋巴结边界、形状大小、内部回声、边缘回声、后方回声、血流分级、血流分布形式、收缩期最高峰值流速（PSV）、舒张末期流速（EDV）、搏动指数（PI）、阻力指数（RI）、速度时间积分（VTI）。术后进行病理检查。结果结核性淋巴结炎与慢性淋巴结炎在结节内部血流分级中有显著性差异，即结核性淋巴结炎结节内部血管明显增多，但二者血流动力学指标无统计学意义。结核性淋巴结炎与恶性淋巴结的血流分级无显著性差异，但二者之间的PSV即收缩期峰值流速有显著性差异，恶性淋巴结的流速明显高于结核性淋巴结炎。结论结核性淋巴结炎血流丰富，但流速并无增快。彩色多普勒血流成像对颌面颈部淋巴结核的诊断有较高的应用价值。
Objective To evaluate the usefulness of color Doppler sonography in diagnosing maxillofacial and cervical tuberculous lymphadenitis and to analyze their pathologic basis. Methods One hundred and eighty-four patients with 224 maxillofaeial and cervical lymph nodes were examined from January 1998 to December 2003. Color Doppler sonography was used to evaluate the masses before surgeries and the diagnosis was confirmed by pathologic examine after the surgeires. Results The intranode vascularity grade of tuberculous was significantly higher than chronic lyrnphnoditis （ P 〈 0.05）, but the blood dynamics parameters did not show difference （ P 〉 0.05）. Tuberculous nodes showed similar vascularity as with the the malignant lymph nodes, but the PSV was much lower. Conclusion Color Doppler sonography is useful in the diagnosis of tuberculosis lymph node.
