中、重度哮喘患者存在气道高反应性,往往伴随有气道平滑肌肥厚,其在哮喘恶化、慢性气流的限制中发挥着作用,一直被视为哮喘发病的重要角色。支气管镜下射频消融支气管热成形术是一种新型的支气管镜介入治疗技术,通过射频探针释放可控制的热能,减少积聚的气道平滑肌,并可降低支气管收缩、狭窄。可减少气道平滑肌数量和改善哮喘控制,在改善哮喘持续状态方面超过目前的治疗方法。 Moderate and severe asthmatics present with airway hyperresponsiveness, often accompanied by airway smooth muscle hypertrophy, which plays a role in the exacerbation of asthma and chronic airflow restriction and has long been regarded as an important role in the pathogenesis of asthma. Bronchoscopic radiofrequency ablation Bronchial thermoplasty is a novel bronchoscopic interventional technique that uses radiofrequency probes to release controlled heat, reduce accumulated airway smooth muscle, and reduce bronchoconstriction and stenosis. Can reduce the number of airway smooth muscle and improve asthma control, in improving the status of asthma than the current treatment.
