Bronchial Thermoplasty

BT is a newly FDA approved treatment for adults with severe, persistent asthma who have significant symptoms despite maximum medical therapy. BT is the only non-pharmacologic therapy available for the treatment of severe asthma and is intended to complement pharmaceutical treatment options. Drs. Fields and deKeratry were the first physicians in Texas to perform this procedure and started treating patients in 2010.

Patients who are deemed appropriate candidates undergo a series of three different bronchoscopic procedures. A radiofrequency catheter array is used by our physicians to treat the bronchial tubes in most areas of the lungs. This technique decreases the size of the smooth muscle in the bronchial walls that is responsible for constricting (or narrowing) the bronchial tubes. Thus, patients have less bronchial spasm.

Treatment with BT has shown a 32% reduction in the rate of severe asthma attacks; a 66% reduction in the number of days lost from work, school, or other daily activities; and an 84% reduction in ER visits for respiratory symptoms. The long-term safety profile is excellent.

Patients who are suffering from severe, persistent asthma should inquire about this treatment option through their primary care provider, allergist-immunologist, or pulmonologist. We also have a BT program coordinator who can field questions and facilitate consultative visits.
