BackgroundThe incidence of secondary tracheal tumours following lung cancer surgery is notably low. Patients with tracheal tumours typically present with symptoms such as coughing, sputum production, haemoptysis, wheezing, stridor, and dyspnoea. In cases of peripheral structure invasion, symptoms may further extend to hoarseness and dysphagia. Initial symptoms may be notably non-distinct. However, the development of pronounced airway symptoms often signifies a critical condition.Case presentationA 70-year-old male with severe chest tightness and asthma was transferred to our hospital for emergency treatment. He had undergone left pneumonectomy for non-small cell carcinoma of the left upper lobe of the lung 3 years prior. The examination confirmed that a secondary tumour originated from the left main bronchus and extended to the carina, occupying 90% of the diameter of the tracheal lumen. To relieve the patient’s emergency airway, we chose right thoracoscopic resection of the tracheal tumour assisted by cardiopulmonary bypass (CPB), which provides extracorporeal lung support and a good surgical field.ConclusionIn patients with secondary tracheal tumours after left pneumonectomy for lung cancer, perioperative airway management is challenging for anaesthesiologists, and patients’ oxygenation should receive close attention. This article describes the airway management process of this patient for reference.
