Balloon dilation treatment for tuberculous airway stenosis / 中国医学装备

ABSTRACT

Objective:By analyzing clinical data, discuss the clinical efficacy of balloon dilatation for the treatment of tuberculous scarred airway stenosis and factors affecting efficacy. Methods:Selected 13 cases airway stenosis caused by tracheobronchial tuberculosis.Airway stenosis was confirmed and measured by bronchoscopy and CT before balloon dilation. Balloon dilatation with forming expansion was conducted once a week. We evaluated the shortness of breath scores, measuring FEV1, FVC and the diameter of airway before and after dilation. The long-term outcome and lung function improvement were evaluated. Results:Thirteen cases were treated by balloon dilation with fiberoptic bronchoscopy. The airway diameter before and after the treatment, shortness of breath score, FEV1, FVC have improved significantly, the difference was significant(t=15.596, t=-27.657, t=-14.604, t=-41.766;P<0.05). Conclusion:Balloon dilation treatment for tuberculous scarred airway stenosis can achieve better results.
