Bronchial Thermoplasty for Severe Asthma With Dynamic Hyperinflation

"Three sessions of bronchial thermoplasty are needed to treat patients. There will be 3 to 4 weeks between each procedure.~Bronchial thermoplasty procedure is performed under general anesthesia. The medical device used in this research to achieve the thermoplasty is the Alair system (class IIb medical device ; Boston scientific)~A confocal endomicroscopy will be conducted at the first and final session of thermoplasty. This examination involves analyzing and recording the structure of bronchi microscopy through a small catheter placed on the bronchus. Photographs of the bronchi will be realized."
