Abstract
Bronchial thermoplasty (BT), which delivers thermal radiofrequency to the bronchial wall, is an effective therapy for patients with severe persistent uncontrolled asthma. We herein report the case of a 47-year-old man who underwent BT for uncontrolled severe asthma. After BT, his asthma control, asthma-related quality of life, and pulmonary function improved. Furthermore, a histologic examination of transbronchial biopsy specimens revealed a decrease in goblet cell hyperplasia and the smooth muscle mass as well as in the subepithelial basement membrane thickness. BT can be effective for patients with severe uncontrolled asthma and mucus hypersecretion.
