Interventional management of tracheobronchial strictures

Figure 3 A 67-year-old man with a left main bronchial stricture caused by non-small-cell lung cancer. A, B: Axial computed tomography (CT) scan (A) and anteroposterior view (B) of 3D surface-rendered reconstruction CT scan performed 3 d before stent placement, showing a severe left main bronchial stricture (arrows); C: Radiograph showing retrievable covered stent (arrows) 12 mm in diameter and 4 cm in length placed at the stricture. A sizing catheter (arrowhead) is also shown; D: Radiograph showing the collapse of the proximal end (arrowhead) of the stent while the retrievable hookwire (arrow) was withdrawn into the sheath; E, F: Axial CT scan (E) and anteroposterior view (F) of 3D surface-rendered reconstruction CT obtained 6 mo after stent removal, showing marked improvement in the stricture (arrows).
