[Experience of a vascular stent placement under bronchoscopy for a severe airway stenosis like a pinhole].

The patient was a 32-year-old woman. She suffered repeated hemoptysis due to a congenital right pulmonary artery deficiency and underwent right pneumonectomy at 19 years of age. Immediately after the operation, postpneumonectomy syndrome appeared. The left main bronchus was compressed and almost obstructed, and so metallic stent was urgently installed. However, she subsequently suffered from repeated stenosis due to granulation and repeated obstructive pneumonia. She underwent 7 stent installations, laser therapy, low dose radiotherapy, and ballooning to treat her airway stenosis. However, her left main bronchus gradually became a severe stenosis like a pinhole. When she admitted to our hospital due to obstructive pneumonia last time, it was impossible to install usual airway stents because of extreme kinking of airway and severe stenosis. Therefore, a vascular stent for iliac artery was chosen to treat her airway stenosis and the stent was placed to regain good patency. As a result of the treatment, she had immediate relief of symptoms and survived obstructive pneumonia.
