Airway Segmented Stent Modified With 3D Printing for Malignant Stricture Involving Carina and Distal Bronchi
Overview
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.

- Procedure: Airway stent implantation
- The airway stents modified with 3D printing were implanted to treat malignant stricture involving carina and bronchi distal to carina.
Arms, Groups and Cohorts
- Experimental: Airway Stent for Malignant Stricture
- Patients with malignant stricture were implanted with covered metallic segmented stent modified with 3D printing.
Clinical Trial Outcome Measures
Primary Measures
- Improvement in Dyspnea using Hugh-Jones classication as criteria
- Time Frame: 3 days
- Hugh-Jones classication: dyspnea scale that includes 5 categories.
- Stent patency time
- Time Frame: 2 months
- Stent patency time is defined as the time from the stent implantation to stent restenosis or death due to any cause, or censored at date last known alive.
- Overall survival
- Time Frame: 6 months
- OS is defined as the time from the stent implantation to death due to any cause, or censored at date last known alive.
Secondary Measures
- Number of participants with adverse events that are related to stent implantation
- Time Frame: 2 months
- Adverse events as follows: migration of the stent, severe chest pain, hemoptysis, granuloma formation, pneumonia and accumulation of secretion
