3-D printouts of the tracheobronchial tree generated from CT images as an aid to management in a case of tracheobronchial chondromalacia caused by relapsing polychondritis. | LitMetric

AI Article Synopsis

  • A 67-year-old man with severe relapsing polychondritis and tracheobronchial issues is facing increasing symptoms, prompting consideration of surgical options like tracheostomy and stenting.
  • Researchers created 3-D models of the patient's trachea by converting dynamic chest CT scans into STL files, enabling a clearer understanding of his airway problems.
  • The report also explores the potential use of these models for regenerative medicine, possibly creating new cartilaginous structures for improved airway function in the future.

Article Abstract

This report concerns a 67 year old male patient with known advanced relapsing polychondritis complicated by tracheobronchial chondromalacia who is increasingly symptomatic and therapeutic options such as tracheostomy and stenting procedures are being considered. The DICOM files from the patient's dynamic chest CT in its inspiratory and expiratory phases were used to generate stereolithography (STL) files and hence print out 3-D models of the patient's trachea and central airways. The 4 full-sized models allowed better understanding of the extent and location of any stenosis or malacic change and should aid any planned future stenting procedures. The future possibility of using the models as scaffolding to generate a new cartilaginous upper airway using regenerative medical techniques is also discussed.
