2. Figure 1
(a) Esophagogram obtained 9 hours after co-axial placement of two overlapping Ultraflex stents inside the old Polyflex stent (arrows point to the characteristic radiopaque bands of the Polyflex plastic stent). Note stasis of the contrast medium in the upper esophagus and right-sided displacement of the proximal stent segment toward the trachea (arrowheads). (b) Urgent CT scan shows complete displacement of the proximal stent into the trachea (arrow). Extensive aspiration pneumonia was also seen (image not shown). (c) Final fluoroscopic image after endoscopic removal of the stent and radiologic placement of another covered stent to seal the eroded tracheal wall. Note the cephalad extension of the second co-axial covered stent (black arrowline).

Multiplanar reformatted CT scan depicts erosion and prolapse of the Flamingo Wallstent into the left main stem bronchus, causing almost complete luminal obstruction (arrow).

Axial (a) and midline sagittal (b) cross-sectional CT scans show erosion of the posterior tracheal wall and stent prolapse into the airway with severe lumen compromise (arrows).
