CTICasesIatrogenic Bronchial Compression from Esophageal Stent
Imaging findings
CT chest shows an esophageal stent-within-stent placed for Boerhaave syndrome. The large diameter of the stent causes direct extrinsic compression of the adjacent left lower lobe bronchus, resulting in persistent atelectasis of the left lower lobe.
Key takeaways
Esophageal stents can cause mechanical mass effect on the adjacent airway, particularly in patients with a narrow AP thoracic diameter. Extrinsic compression of the left lower lobe bronchus can lead to airway obstruction, secretion retention, and persistent lobar collapse.
