【摘要】：目的探讨支气管扩张量化指标与患者临床症状之间的关系及其对临床症状的预测价值。方法基于计算机支气管扩张定量测量技术,回顾性搜集确诊为支气管扩张症的45例患者,采集临床信息并搜集24 h咳痰量、咯血量,应用Dexin-FACT软件分析CT图像,自动检测所有扩张支气管各种量化指标,分析咳痰量、咯血量与支气管扩张量化指标间的关系。结果 24 h咳痰量与平均扩张程度、双肺下叶支气管累及总数正相关性(r=0.704,r=0.528),而与所有扩张支气管最大扩张程度、平均壁厚、平均内直径不相关。咯血量与扩张支气管总数、扩张最大支气管位置、平均WA%及平均扩张程度相关(r=0.539,r=-0.354,r=0.355,r=-0.568),而与扩张程度最大支的扩张程度和距离隆突距离及最大扩张程度支气管的壁厚不相关。结论扩张支气管平均扩张程度越大,双肺下叶扩张支气管总数越多,咳痰量越多。扩张支气管总数越多、平均WA%越大,咯血量越多;扩张程度最大支支气管位于双肺上叶,咯血量较多。
[Abstract]:Objective to explore the relationship between bronchiectasis and clinical symptoms and its predictive value. Methods based on the quantitative measurement of bronchiectasis, 45 patients with bronchiectasis were collected retrospectively. The clinical information was collected and 24 h expectoration and hemoptysis were collected. Ct images were analyzed by Dexin-FACT software. To analyze the relationship between expectoration, hemoptysis and bronchiectasis. Results the amount of expectoration at 24 h was positively correlated with the average degree of dilatation, the total number of bronchi involved in the lower lobe of the lungs was positively correlated with 0.704 of bronchiolitis, but not with the maximum degree of dilated bronchiectasis, the average wall thickness and the mean internal diameter of all dilated bronchi. The amount of hemoptysis was correlated with the total number of dilated bronchi, the position of the largest dilated bronchus, the average WA% and the average degree of dilatation. Conclusion the greater the average dilatation degree of the dilated bronchi, the more the total number of dilated bronchi and the more expectoration. The larger the total number of dilated bronchi, the larger the average WA% and the larger the hemoptysis.
