[Airway stenting with inhalation anesthesia in malignant airway stenosis or fistula under radiological guidance].

OBJECTIVE: To assess the efficacy and safety of airway stenting with inhalation anesthesia under radiological guidance in the palliation of malignant tracheobronchial stenosis.

METHODS: Between June 2001 and August 2010, 74 consecutive patients with malignant tracheobronchial stenosis were treated by the insertion of an ultraflex self-expandable metal stent with inhalation anesthesia under fluoroscopic guidance.

RESULTS: All patients achieved obvious symptomatic relief. The outcomes were as follows: dyspnea (n = 2), long-term angina (n = 1), strong irritation cough (n = 2), hard phlegm (n = 3), clotting expectoration (n = 3), blood-tinged expectoration (n = 64), airway stent displacement (n = 1) and tracheoesophageal fistulas (n = 1).

CONCLUSION: Performed with inhalation anesthesia under radiological guidance, tracheobronchial recanalization with a self-expandable metal stent is a safe and effective palliative treatment for malignant stenosis.
