Stent-in-Stent Technique for the Treatment of Proximal Bronchial Restenosis after Insertion of Metallic Stents: A Report of Two Cases

Figure 1

(a) Endoscopic view of the near-complete posttransplant restenosis of the right bronchus intermedius. A small residual orifice allows a recanalization by forceps first and then balloon dilation and argon plasma therapy. (b) Endoscopic view of the previously inserted metallic stent in the right bronchus intermedius below the proximal stenosis. The distal end is patent but anchored in a highly inflammatory tissue. (c) View of the proximal end of the newly inserted stent using the stent-in-stent technique. Note the spherical end with a higher diameter (10 mm instead of 8 mm, white arrow) and the patent right upper bronchus (yellow arrow). (d) Endoscopic view of the distal end of the prosthesis 1 month later. The right lower lobe is ventilated and inflammation is resolved.
