A migrated Polyflex stent in the right main bronchus was missed on chest X-ray. Clinical symptoms, not just imaging, are crucial for diagnosing stent migration, especially with radiopaque devices.

Area of Science:

  • Medical device safety
  • Respiratory medicine
  • Interventional pulmonology

Background:

  • Tracheal stenosis management often involves indwelling stents.
  • Polyflex stents are designed to be radiopaque for visibility.
  • Accurate stent placement and monitoring are critical for patient outcomes.

Observation:

  • A case of tracheal stenosis with a Polyflex stent migrating into the right main bronchus is presented.
  • The migrated stent was not initially visible on standard chest radiography.
  • Bronchoscopy successfully identified and located the misplaced stent.

Findings:

  • Polyflex stents, despite being radiopaque, may not be reliably detected on routine chest radiographs.
  • Clinical presentation can be a more sensitive indicator of stent migration than initial imaging.

  • The migrated stent was successfully removed under general anesthesia via bronchoscopy.

    • Implications:

    • Relying solely on imaging for stent migration diagnosis can be misleading.
    • Clinical assessment should guide the suspicion and investigation of stent migration.
    • When stent migration is suspected, specialized imaging like thoracic inlet films with a lateral view may be necessary for detection.
