Imaging findings
A patient with esophageal rupture was treated with a covered self-expanding esophageal stent across the gastroesophageal junction plus drains, and the stent was fully expanded on the initial CT. CT about a week later shows the stent has partly collapsed, with the distal end still visible. Comparing the radiographs side by side, the change can be seen in retrospect but is very hard to spot prospectively.
Key takeaways
Self-expanding esophageal stents are often used to temporarily cover ruptures and anastomotic leaks, and they can collapse on their own. Possible causes include the angle where the esophagus turns from vertical to horizontal, incomplete expansion, or strong esophageal contractions. Compare stent shape and diameter between studies, because the change can be subtle on radiographs. This stent was removed.
