Outcomes of Tracheobronchial Stents in Patients With Malignant Airway Disease

Tracheobronchial stents offer minimally invasive palliative therapy for patients with unresectable malignant central airway obstruction. The benefit of airway stents is particularly seen in the short-term period where they provide symptomatic improvement and have low complication risk. The major impediment is excessive granulation tissue and tumor ingrowth, which occur primarily after 30 days.
