Bronchodilator interventions are generally very effective in most cases. Bronchodilator interventions are mainly used for ruptured bleeding of blood vessels due to airway inflammation, especially in case of aggressive hemoptysis, mainly to examine the site of bleeding and to perform the appropriate hemostatic treatment. It is usually performed under local anesthesia through the skin and then through the femoral artery, through a puncture tube all the way to the level of the bifurcation of the trachea, with catheter pushing under imaging fluoroscopy to clarify the site of the bronchial artery rupture. At this point, hemostasis can be performed accordingly, and the operation is relatively minimally invasive, with rapid, safe and reliable results.
