Restoring the "Gate of Breath": Advanced Interventional Pulmonology for Complex Airway Obstructions
The Challenge of Malignant Airway Obstruction
At the beginning of 2026, the Interventional Pulmonology Division at the Respiratory and Critical Care Medicine Center of Beijing Chaoyang Hospital confronted two high-stakes clinical emergencies. For patients with advanced-stage malignancies, central airway stenosis (CAS) is a life-threatening complication that leads to severe respiratory failure, often rendering traditional ventilation methods ineffective.
Led by Professor Wang Feng, Associate Director of the Center and Head of the Interventional Pulmonology Group, our team executed two rapid-response interventions to reopen the "Gate of Breath" for patients on the brink of asphyxiation.
Case I: Managing Extrinsic Compression via Metallic Covered Stents
Patient L, with a history of thyroid cancer, presented with a massive mediastinal tumor that had progressively compressed the mid-trachea over three months. Diagnostic CT imaging revealed a critical narrowing of the airway, with a stenosis degree exceeding 80%. The patient was unable to lie supine and suffered from acute respiratory distress.
Following a Multidisciplinary Team (MDT) consultation, Professor Wang Feng’s team opted for a combined approach using rigid bronchoscopy and flexible bronchoscopic guidance. Under intravenous anesthesia, the team precisely deployed a metallic covered stent. This specific stent was chosen to provide robust radial support against the extrinsic tumor mass while preventing endobronchial tumor ingrowth. The procedure resulted in immediate symptomatic relief, and the patient reported significantly improved ease of breathing by the following morning.
Case II: Emergency Recanalization for Esophageal Cancer Invasion
Patient Z presented with acute-onset dyspnea. Clinical evaluation and CT imaging confirmed that an esophageal malignancy had not only compressed but also directly invaded the trachea (Zones III and IV). This type of malignant infiltration poses an extreme risk of sudden airway collapse.
Recognizing the urgency, the team initiated an emergency surgical protocol. To stabilize the patient’s breathing immediately, the team first performed balloon dilation to expand the narrowed segment. This was followed by the rapid deployment of a straight silicone-coated stent to maintain patency. The seamless coordination between the interventional team and the Department of Anesthesiology ensured the airway was secured within minutes, successfully averting a fatal outcome.
Technical Leadership in Respiratory Intervention
These successful outcomes highlight the technical proficiency of Beijing Chaoyang Hospital in the field of interventional pulmonology. Our team specializes in the "Rigid-Flexible Synergy" technique, which offers several clinical advantages:
- Enhanced Safety: Rigid bronchoscopy provides a stable artificial airway and superior suction capabilities during high-risk maneuvers.
- Precision Placement: Real-time endoscopic guidance ensures that stents are positioned with millimeter accuracy to avoid blocking healthy bronchial branches.
- Comprehensive Solutions: From balloon dilation to various stent types (metallic, covered, or Y-shaped), we tailor our approach to the specific pathology of each patient.
Commitment to Life
Whether managing routine cases or responding to critical emergencies, our mission remains the same: to provide world-class, minimally invasive respiratory care. We are dedicated to pushing the boundaries of medical technology to ensure that even patients with advanced cancer can breathe with dignity and comfort.
