Abstract
The utility of stent placements has been widely reported. We performed a thought-provoking stent placement for malignant tracheal stenosis recently. A 90-year-old woman who was admitted to our hospital because of a urinary tract infection was treated with a course of antibiotics, but she demonstrated a rapidly progressive course with dyspnea. Chest computed tomography showed severe tracheal stenosis due to an upper mediastinal mass. She was put on noninvasive positive pressure ventilation (NPPV) because of severe respiratory failure. Bronchoscopy showed severe tracheal stenosis due to direct invasion by the upper mediastinal mass. An expandable metallic stent (EMS) was placed in the trachea, after which a bronchoscopy showed a widely patent airway, and she got off NPPV. Then she did not need supplemental oxygen. She could seat herself, and have an enough meal, independently. However, takotsubo cardiomyopathy occurred and she died 11 days after the placement of the EMS. Since a malignant airway complication can be fatal, tracheal stent placement is a useful treatment in the management of malignancy with airway stenosis. In this case, it was thought that an early intervention of airway stenosis would have reduced the risk of takotsubo cardiomyopathy in a patient with severe symptoms of airway stenosis and stress.
