Abstract
We report a case of a 55-year-old woman with a tracheal stenosis caused by recurrent lung cancer. After balloon dilation under endoscopic control, the Nitinol stent was implanted in the trachea. Dyspnea, stridor and bloody sputum were markedly improved after placement. However, two days after placement, giant granulation tissue was expectorated with coughing. Fortunately, acute airway obstruction did not occur. The Nitinol stent has a variety of excellent properties and is easy to manipulate. Although complications are rate for the Nitinol stent compared to other metallic stents, acute airway obstruction within three days after placement has been reported. To prevent acute airway obstruction due to mucoid impaction, bronchial toilet, nebulization and antibiotics are very important.
