CTICasesTracheoesophageal fistula with migrated esophageal stent clips
Imaging findings
CT scan of a patient with a large tracheoesophageal fistula (TEF) shows a bifurcated tracheal stent. Metal hemostatic clips previously used to anchor an esophageal stent had migrated through the fistula into the left mainstem bronchus and distal lung, which the patient subsequently expectorated.
Key takeaways
Hemostatic clips used to secure esophageal stents can migrate through a tracheoesophageal fistula into the airway. Patients may occasionally expectorate these migrated clips.
