RESUMO
Objective:To explore the efficacy, safety and feasibility of airway stent underwent through the endotracheal tube by the guidance of DSA for tracheal stenosis.Methods:36 patients (26 men and 10 women) with severe airway stenoses received a general anesthesia. After the patients were anesthetized, the stents were placed through the endotracheal tube with fluoroscopic guidance. Arterial blood oxygen saturation, the Karnofsky Performance Status (KPS) score and the survival time after placing the stents were assessed.Results: There were significant differences between preoperative arterial blood oxygen saturation and after the operation, and there were significant differences between preoperative Karnofsky Performance Status (KPS) score and postoperative KPS score.Conclusion:Stent placement through the endotracheal tube under general anesthesia can effectively relieves the airway stenosis. The technique was feasible, simple and safe, and it can provide a novel and safe method for the treatment of airway stenosis.
