Bronchial Thermoplasty

Le résumé fourni par la source

Severe uncontrolled asthma in patients maximized on pharmacologic therapy accounts for a majority of morbidity and mortality associated with asthma. Bronchial Thermoplasty (BT) is a non-pharmacological FDA-approved bronchoscopic intervention that delivers thermal energy via endobronchial radio frequency wave catheter to the bronchial airways. BT was designed prior to the advent of biologic therapy to assist in controlling severely uncontrolled asthmatics. The principal goal of this procedure is to reduce airway smooth muscle in the bronchial airways. The benefits of bronchial thermoplasty can be in reducing airway hyper-responsiveness, optimizing asthma control, decreasing asthma exacerbations and stepping down on asthma therapy, including steroids. A crucial component prior to relegating a patient to the procedure is ensuring appropriate patient selection in efforts to maximize benefits and minimize risks associated with the procedure. Complications after bronchial thermoplasty are often seen and predominately involve exacerbation of underlying asthma, atelectasis, respiratory tract infection and hemoptysis.
