Abstract: Objective?To investigate the practicality and safety of flexible fiberoptic bronchoscope-assisted placement of airway stents to relieve central airway stenosis caused by malignant tumour under mechanical ventilation.?Methods?The fiberoptic bronchoscope and the tracheal tube were inserted into the airway in parallel under mechanical ventilation, and the metal airway stent was placed in through the tracheal tube under the guidance of fiberoptic bronchoscope.?Results?11 patients with malignant airway stenosis received this procedure. After stent placement, central airway stenosis was relieved, and the symptoms of hypoxia were alleviated in all of the patients. The operation was smooth, and all the patients were weaned from mechanical ventilation. After stents were implanted, dyspnea scores, airway stenosis and airway pressure were improved significantly (P?
