目的 探讨肺段和肺段以下气道结构的造影方法和诊断价值。方法 在DSA下经纤支镜气囊导管选择性支气管造影研究咯血患者 2 7例。造影剂为国产 76 %泛影葡胺。结果 行选择性肺叶支气管造影 14次、肺段支气管造影 31例次和亚段支气管造影 2次 ,全部图像清晰 ,达到诊断目的。阳性检出率为 96 .30 % ,其中支气管扩张 6例占 2 2 .2 2 %、结核 7例占 2 5 .93%、肺癌 4例占 14.81%。结论 用气囊阻塞近端支气管达到定量选择性支气管造影效果。提出支气管造影的四个时相 ,有深入研究价值。
Objective To investigate the radiographic methods and diagnostic value of the airway structures below the pulmonary and pulmonary segments. Methods Twenty-seven patients with hemoptysis under bronchofibroscope selective bronchography under DSA were studied. Contrast agent for domestic 76% diatrizoate. Results of selective bronchial bronchography 14 times, 31 cases of pulmonary bronchography and sub-bronchography 2 times, all the images clear, to achieve the purpose of diagnosis. The positive detection rate was 96.30%, of which 6 cases accounted for 22.2% of bronchiectasis, 7 cases of tuberculosis accounted for 25.93% and 4 cases of lung cancer accounted for 14.81%. Conclusion The use of balloon occlusion of the proximal bronchus to achieve quantitative selective bronchography. Put forward the four phases of bronchography, in-depth research value.
