Figure 1 Images of a bronchial stent. (a) The bronchial stent is flared proximally (left) and distally (right). (b) Two drawstrings (arrows) and nylon loops (arrowheads) are attached to the proximal inner portion of the stent.

Figure 2 Illustration of technical steps of bronchial stent removal. (a) A sheath with a dilator is passed down over the guide wire into the proximal stent lumen, and the dilator is replaced with a hook wire. (b) The sheath (arrowheads) with the hook wire (arrow) is then pulled out of the stent so that the hook grasps the nylon drawstring of the stent. (c) The proximal end of the stent is being collapsed while the hook wire is withdrawing the drawstring into the sheath. (d) The entire assembly is then pulled out of the bronchus.

Figure 3 Images from a 36-year-old woman (patient 9) with a left main bronchial stricture. (a) A chest radiograph just before stent placement shows total left lung collapse. (b) A three-dimensional CT image shows total occlusion of the left main bronchus (arrows). (c) A chest radiograph 1 day after stent placement shows marked improvement of the lung collapse. (d) A chest radiograph obtained 7 months after stent removal shows a well-expanded state of the left lung. The stent had been placed for 6 months before removal.
