Bronchiolitis obliterans is a type of obstructive lung disease of the small airways, a form of chronic allograft rejection after lung transplantation. The most of lung transplant recipients who are long-term survivors develop bronchiolitis obliterans syndrome. It is estimated that more than 50% of recipients will develop some degree of BO within 5 years post-transplant, with an average time to diagnosis of 16 to 20 months after lung transplant, although it has been reported as early as 3 months after transplantation.
