摘要
目的 提高超声对肝门区及腹腔干周围淋巴结肿大的检出率 ,并探寻其临床意义。方法 分析 67例经手术及病理证实的肝门区及腹腔干周围淋巴结肿大患者的二维超声图像及彩色多谱勒检测结果。结果 67例患者中恶性淋巴结肿大 5 0例 ,良性淋巴结肿大 17例。良恶性淋巴结肿大在数目、分布、大小、纵横比、边界、皮质回声等方面差异小 ,而皮质类型、淋巴结门声像图表现差异大。肿大淋巴结的血流信号检出率低 (2 2 % ) ,如检出血流信号 ,则良恶性淋巴结的动脉频谱阻力指数 (RI)差异大。结论 超声检测肝门区及腹腔干周围淋巴结的意义首推肿大淋巴结的检出率和范围 ,其次才是淋巴结良。
Objective To improve the Ultrasound detection rate for the enlarged lymph node in the porta hepatis area and cliac artery(CA)round and elvaluate its clinical significance.Method We analysed the Ultrasound features and the Doppler spectrum the 67 enlarged of lymph nodes confirmed by operation or pathology to be in the porta hepatis area and CA round.Result Among the 67 cases,the enlarged lymph nodes in 50 cases were maliganant while in the other 17 case were benign.The number,size,ratio of length to width,margin and cortex echo of the malignant and benign enlarged lymph nodes were not significantly different.The cortex type and ultrasound feature of the malignant and benign lymph nodes,however,were remarkably different.The detection rate of the flow signal of the enlarged lymph nodes was low ,but so long as the flow signals were detected within or around the nodes,the resistence index of it was different between malignant and benign nodes.Conclusion The significance of ultrasound in detecting enlarged lymph nodes in the porta hepatis area and cliac artery is first to reveal the range,then to differentiate its characteristic.
