A Case of Hybrid Stent Placement Following Bronchial Artery Embolization for Bleeding Airway Stenosis due to Mediastinal and Hilar Lymph Node Metastasis by Renal Cell Carcinoma

Here, we report a rare case of severe central airway obstruction caused by mediastinal and hilar lymph node metastases with persistent bleeding from renal cell carcinoma. Hemoptysis and critical left main bronchial stenosis were initially managed with bronchial arterial embolization, which reduced the risk of bleeding during subsequent interventions. This enabled safe placement of an AERO airway stent, leading to a rapid improvement in respiratory status. The patient was able to proceed with systemic therapy without delay. This case demonstrates the value of combining bronchial arterial embolization (BAE) with airway stenting as an effective bridge strategy for the treatment of life‐threatening malignant airway stenoses.
