Abstract: With the continuous improvement of surgical techniques and perioperative management, the success rate of lung transplantation has gradually increased, but airway complications after lung transplantation are still common. Airway complications after lung transplantation may reduce the quality of life, increase medical costs, and even threaten the lives of the recipients. In 2018, the International Society for Heart and Lung Transplantation (ISHLT) consensus proposed that airway complications included ischemic necrosis, anastomotic dehiscence, airway stenosis and tracheobronchomalacia. Bronchoscopy remains the gold standard for the diagnosis of airway complications. However, during the follow-up of lung transplant recipients, use of end-inspiratory CT scan combined with end-expiratory or dynamic expiratory CT scan may contribute to identifying a variety of airway complications, evaluating the location and degree of airway complications and providing beneficial supplement for the selection of clinical treatment.
