Bilateral self-expandable metallic stents for lung cancer involving the carina

Central airway obstruction needs interventional pulmonology and malignant main carinal involvement is one of the most challenging scenarios requiring rigid bronchoscopic intervention under general anesthesia. However, these patients tend to be in poor condition for such interventions. A 91-year-old male patient with lung cancer accompanied by obstructive pneumonia underwent an Ultraflex self-expandable metallic stent placement in the right mainstem bronchus. The extranodal extension of the carcinoma from mediastinal lymph nodes metastases to the carina was so fast that severe stenosis of the bilateral mainstem bronchi was observed 6 weeks later accompanied by the deterioration of dyspnea. To salvage the carina, bilateral Ultraflex covered stents were placed by “side-by-side” method using fiberoptic bronchoscopy under topical anesthesia. This strategy was quite safe and the time needed for the entire procedure was within 20 min. He never experienced dyspnea thereafter and died of a cardiac sudden death 7 months after the initial stenting.
