Imaging findings
CT angiography demonstrates severe narrowing (stenosis) of the right main bronchial anastomosis with associated high-attenuation material within the lumen. Downstream mucous plugging, secretions, and regional air trapping are visible in the right lower lobe. Bronchoscopy confirms significant narrowing with necrotic, sloughing tissue and granulation tissue.
Key takeaways
Bronchial anastomotic complications, such as stenosis, dehiscence, or necrosis, are important causes of declining pulmonary function post-lung transplant. They can result from ischemic injury and subsequent granulation tissue formation, and they are typically managed with bronchoscopic debridement and/or dilation.
