Brief summary
In this study, we used the covered metallic segmented airway stent to treat malignant strictures involving carina and bronchi distal to carina and aimed to determine the feasibility, efficacy and safety of this technique.
Interventions
The airway stents modified with 3D printing were implanted to treat malignant stricture involving carina and bronchi distal to carina.
