Outcome Measures

Primary Outcomes (3)

  • Improvement in Dyspnea using Hugh-Jones classication as criteria

    Hugh-Jones classication: dyspnea scale that includes 5 categories.

    3 days

  • Stent patency time

    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.

    2 months

  • Overall survival

    OS is defined as the time from the stent implantation to death due to any cause, or censored at date last known alive.

    6 months

Secondary Outcomes (1)

  • Number of participants with adverse events that are related to stent implantation

    2 months

Study Arms (1)

Airway Stent for Malignant Stricture

EXPERIMENTAL

Patients with malignant stricture were implanted with covered metallic segmented stent modified with 3D printing.

Procedure: Airway stent implantation

Interventions

The airway stents modified with 3D printing were implanted to treat malignant stricture involving carina and bronchi distal to carina.
