Abstract

Objective: Determine the association between high-resolution computed tomography (HRCT) findings and pulmonary function in patients with bronchiectasis.

Methods: A prospective, descriptive study of 66 patients with bronchiectasis who had HRCT at National Lung Hospital from September 2017 to June 2018.

Results: Cystic bronchiectasis accounts for 68.2%, 77.3% of cases are bilateral patterns. Middle lobe bronchiectasis accounts for the highest rate of 71.2%; followed by the lower lobes which accounts for 53%. A notable proportion (33.3%) of patients with bronchiectasis had diffuse lesions affecting both lungs. 65.2% of patients with bronchiectasis did not have pulmonary function disorders, however, obstructive ventilation impairment was present in 19.7% of cases. The cystic bronchiectasis group demonstrated the lowest average indexes of pulmonary function. Bilateral diffuse bronchiectasis was associated with significantly reduced pulmonary function compared to focal bronchiectasis that only affect one lung. There was a gradual decrease in the average indexes of pulmonary function as the number of damaged lung lobes increased.
