气囊导管选择性支气管造影的应用研究

Selective bronchography with balloon catheter

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 explore the selective brochography and it's diagnositic value to segment bronchopulmonalia and smaller bronchial structure. Methods Under DSA guideness, selective bronchography by balloon catheter combined with fiberoptic bronchoscopy was studied in 27 patients with hemoptysis, contrast medium was 76% urografin. Results All images were clear that included 14 selective lobar bronchographies, 31 segmental bronchographies and 2 subsegment bronchographies. The positive rate was 96.3%, including bronchiectasis 22.22%, tuberculosis 25.93% and lung cancer 14.81%. Conclusion Quantitative selective bronchography could be achieved by blocking the proximal bronchus with balloon, we suggested to pay attention to the four phases of the selective bronchography for future research.
