Question

Quizplus · Accepted Answer

After lung transplantation, the most common cause of airway occlusion is bronchiolitis obliterans, which is characterized by progressive fibrosis and inflammation of the small airways. Compression atelectasis, bronchiectasis, and bronchiolitis may also occur after lung transplantation but are less likely to result in airway occlusion.
