Airway Vascular Changes After Lung Transplant: Potential Contribution to the Pathophysiology of Bronchiolitis Obliterans Syndrome

This study suggests early and persistent airway vasculature changes occur in lung transplant recipients, mainly manifested as microvascular enlargement. Potentially this baseline change contributes to airway obstruction and also puts all lung transplant recipients at risk for further exponential loss of airway caliber with any subsequent airway inflammatory insult.
