When scarring causes right main bronchial stenosis, bronchial balloon dilatation and tracheal stent implantation can be taken as treatment. When the scar causes right main bronchial stenosis, it will seriously affect the function of the respiratory tract, and it is easy to have difficulty in breathing or even suffocation. At this time, effective surgical methods such as bronchial balloon dilatation and bronchial stenting are needed to open the right main bronchus. 1. Bronchial balloon dilatation: physical dilatation of the right main bronchial stenosis with the use of a balloon is mainly used for benign stenosis of the bronchial tube, such as bronchial tuberculosis, scarring stenosis caused by local inflammation and trauma. While cleaning the scar tissue under bronchoscopy, the balloon can be used for airway dilatation to restore the open and unobstructed state of the airway and to relieve symptoms such as dyspnea, coughing and breath-holding. 2. Tracheal stent implantation: It is a kind of pulmonary interventional technique of tracheal implantation, the main purpose of which is to relieve airway stenosis, improve ventilation function, and improve the quality of life. On this basis, airway stability remodeling surgery can also be carried out through airway stenting, which is suitable for patients with postoperative airway scar stenosis, such as tracheal stenosis caused by tracheotomy surgery for lung tumor and tracheal stenosis caused by mediastinal tumor compression. It is also important to pay attention to the treatment of underlying diseases such as tuberculosis and tumors. When scarring causes right main bronchial stenosis, it is important to consult a doctor in time and follow the doctor’s instructions for examination and treatment to avoid triggering serious consequences such as asphyxia.
