obliteration of bronchioles by scarring following bronchiolitis obliterans. Compare: proliferative bronchiolitis.

constrictive bronchiolitis

A pulmonary disorder characterised by air trapping due to narrowing of the bronchiolar lumen secondary to submucosal fibrosis.

Aetiology
Lung, heart-lung or bone marrow transplantation, but also linked to aspiration, connective tissue disease, drugs, infection, and toxic inhalants.

Clinical findings
Dyspnoea, cough, history of transplantation, infections, or toxic exposure.

Management

Prognosis
Guarded.
