Core Tip

Core Tip: The incidence of venous thromboembolism after lung transplantation (LT) contributes to morbidity and mortality. Due to the loss of dual blood supply after LT, a hypoxic milieu exists in the bronchial mucosa of the transplanted lung. Due to the tenuous blood supply, any embolism to the transplanted lung can worsen the hypoxia. This leads to ischemia of the bronchial wall and airway complications. Persistent hypoxia often leads to fibrosis and may contribute to the development of chronic lung allograft dysfunction. Since venous thromboembolism following LT is often asymptomatic, routine screening would be beneficial to patients.
