Aneumatosis of the right inferior lobe with evolution to atelectasis due to a carcinoma that occludes its bronchus. The fissure in this lobe will move towards the vertebral column during collapse. The indication of stents in distal or lobar bronchi was controversial (Journal of Bronchology & Interventional Pulmonology 24: 3; 211-215.2017). Here from the inside … Read more
Punctate stenosis of the left source bronchus. Sequela of extra primary pulmonary tuberculosis (photograph already exposed in tuberculosis and its sequels).
Proper position: these stents of the tracheal stenosis model were “embraced” by the stenosis and their ends “float” in the trachea avoiding contact with their mucosa and anticipate a stay free of complications.
Cured stenosis: just a thin fibrous arch on the floor of the trachea (upper area of the image) and a slight reduction of the light is the result of the repeated dilation treatment. Dilated mucous glands also appear in the foreground of the image.
The incrustation of secretions occurs more frequently in prostheses of tracheal location and forces their replacement. This stent avoids the restenosis of the surgical reimplantation of the left source bronchus in the trachea, after a severe trauma to the thorax by accident.
Several keloids on surgical scars on the neck. Keloids are strikingly common in cases where benign tracheal stenosis develops in patients who have been subjected to orotracheal intubation. External appearance of the trachea in the area of the stenosis. Resection and end-to-end anastomosis as the definitive solution for a recurrent stenosis.
Very thick secretions occupy a stent implanted in a left main bronchus that was sectioned and reinserted in the trachea, away from the carina.
Side cut scissors in “penguin head” ready to make a window in the wall of a silicone stent implanted in the left source bronchus. A positional defect caused the stent to partially obstruct the entry of the ipsilateral upper lobe bronchus, despite several attempts to reposition the prosthesis. Now a metal spike with the hooked … Read more
Arrangement in “omega” of a stent released inside the bronchial lumen. Different maneuvers will be necessary to complete its expansion. This task will be rewarded by the absence of migration that occurs after the implantation of stents that do not expand spontaneously and immediately. This occurs when prostheses of a wide diameter are chosen in … Read more
Here the alligator clamp takes the edge of a stent. By rotating the clamp, the silicone stent is folded, thus eliminating its radial force, and can be easily extracted.
