Abstract:
We report a 48-year-old female patient hospitalized with dyspnoea, wheezing, and respiratory failure due to bilateral main bronchial stenosis from granulomatosis with polyangiitis (GPA) involvement. By computed tomography imaging and flexible bronchoscopy, we measured the narrowest diameter at 2 mm. The patient promptly recovered from respiratory failure after treatment with flexible bronchoscopic balloon dilatation (BBD) without any procedure-related adverse event. This report showed the benefits of urgent flexible BBD that was used as a rescue therapy in a GPA patient who presented life-threatening acute respiratory failure from severe bilateral bronchial stenosis.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
