Purpose: To assess the effectiveness of airway stenting performed exclusively under radiological guidance for the palliation of malignant tracheobronchial strictures.
Methods: We report our experience in 16 patients with malignant tracheobronchial stricture treated by insertion of 20 Ultraflex self-expandable metal stents performed under fluoroscopic guidance only. Three patients presented dysphagia grade IV due to esophageal malignant infiltration; they therefore underwent combined airway and esophageal stenting. All the procedures were performed under conscious sedation in the radiological room; average procedure time was around 10 min, but the airway impediment never lasted more than 40 sec.
Results: We obtained an overall technical success in 16 cases (100%) and clinical success in 14 patients (88%). All prostheses were successfully placed without procedural
complications. Rapid clinical improvement with symptom
relief and normalization of respiratory function was obtained in 14 cases. Two patients died within 48 hr from
causes unrelated to stent placement. Two cases (13%) of
migration were observed; they were successfully treated
with another stent. Tumor overgrowth developed in other 2
patients (13%); however, no further treatment was possible
because of extensive laryngeal infiltration.
Conclusions: Tracheobronchial recanalization with selfexpandable metal stents is a safe and effective palliative treatment for malignant strictures. Airway stenting performed exclusively under fluoroscopic view was rapid and well tolerated.
