肺癌纵隔肺门淋巴结转移的DSA研究

DSA Studies of Mediatinal and Hilar Lymphonodal Metastases of Lung Cancers

笔者分析了５３例原发性支气管肺癌纵隔或／和肺门淋巴结转移的选择性支气管动脉造影的ＤＳＡ表现，结果表明ＤＳＡ显示纵隔、肺门淋巴结转移的准确性高，其主要影像特征有血管粗细不均、血管拉直变硬、血管呈弧形推压、淋巴结染色及少供血改变。本文还重点讨论了淋巴结血供的解剖学和病理解剖学基础、ＤＳＡ的影像特征及其临床应用价值和限制。

The authors reported the demonstrations of selective bronchial arteriographic DSA evaluation of mediatinal and hilar metastases of Lung cancers in 53 cases. The results of DSA manifasted better accuracy, the imaging characterizations of which revealed irregular, rigid, curved arteries,and lymphonodal coloration and little supplied arteries. The anatomic and pathologic bases of lymphonodal suppled arteries, the imaging changes and clinical valuations and limitations of DSA also were disussed.
