Study lung funtion and images High-Resolution Computed Tomography in patients with bronchiectasis in the Thai Nguyen Central Hospital aims: The relationship between clinical characteristics, lung funtion with bronchitis on film morphology Computed tomography chest high resolution easy bronchiectasis patients, the authors performed studies in 35 patients human bronchiectasis, not selected patients with a history of smoking, the method describes the clinical characteristics: the number of sputum, hemoptysis, dyspnea, fever, body mass index, pulmonary ventilation indices: FEV 1 percent, FVC, images HRCT chest: location, morphology bronchiectasis. The authors obtained the following results: Study subjects had an average age of 57.5 +/- 18.2, equal distribution of patient gender, history of pulmonary tuberculosis accounted for 42.2 percent, 60 percent lean patients fever of 48.5 percent, 31.4 percent dyspnea. much phlegm ( 100 ml) with 2/35 patients, hemoptysis 22.8 percent, FEV 1 percent was 79.4 +/- 21.6, obstructive airway 11.4 percent, Patients with mixed ventilatory impairment 24.3 percent. Localized primarily seen relaxing in one lobe, only 5.7 percent diffuse bronchiectasis, cylindrical bronchiectasis 54.2 percent, cystic bronchiectasis 45.8 percent, fever and dyspnea difficulties encountered high rate of patients cystic bronchiectasis, cystic bronchiectasis associated with reduced FEV 1 and FEV 1/ FVC with statistical significance. The proportion of patients with hemoptysis were more in cystic bronchiectasis group, but no statistical correlation is due to the limited data.
