[Dynamic stent useful for trachocarinal stenosis due to lung cancer].

In this study, a new tracheobronchial stent was used for treating a patient with tracheocarinal stenosis due to lung cancer. The patient was 41 year-old male with lung mass in the right upper lobe and metastatic mediastinal lymph node which caused tracheocarinal stenosis. The stent was introduced under general anesthesia with a jet ventilator. The respiratory condition of the patient could be controlled fairly well, and the ventilation tube didn't interfere with the stenting. The stent was a tracheobronchial silicone stent provided with a flexible posterior membrane and tracheal cartilage-shaped steel struts. Coughing is less difficult than other stents owing to better design. This patient has been able to cough up sputum from the day of the operation and there has been no need for bronchoscopic examination for removal of secretions.
