Official title
Development of a CT-Derived Risk Score to Guide Treatment Decision: Tracheal Stenosis Morphology and Attenuation Score (TSMAS)
Overview
This study aims to develop a CT-based scoring system to help predict whether patients with tracheal stenosis will require surgical treatment or can be managed with endoscopic procedures. Using retrospective data, researchers will evaluate CT scans of patients diagnosed with tracheal stenosis to measure features such as airway diameter, wall thickness, and tissue density (measured in Hounsfield Units). The goal is to create a non-invasive, reproducible, and objective tool-called the Tracheal Stenosis Morphology and Attenuation Score (TSMAS)-that can support clinical decision-making and improve treatment planning.
Interventions
- Other CT-Based Morphologic and Attenuation Scoring
Retrospective analysis of CT images to extract morphological and Hounsfield Unit (HU) parameters for development of a predictive scoring model (TSMAS). No clinical or therapeutic intervention was performed.
Primary outcome measures
- Prediction of Surgical Requirement Based on Tracheal Diameter on Initial CT [Time frame: From initial diagnosis to surgical decision (up to 12 months)]
- Prediction of Surgical Requirement Based on Tracheal Wall Thickness on Initial CT [Time frame: From initial diagnosis to surgical decision (up to 12 months)]
- Prediction of Surgical Requirement Based on HU Values of the Stenotic Segment on CT [Time frame: From initial diagnosis to surgical decision (up to 12 months)]
Eligibility criteria
Inclusion criteria
