What disease is pulmonary bulla

summary

The lung is the only place in our body where we can exchange air with the outside world. There are many alveoli participating in the gas exchange. Let's share the knowledge about pulmonary bullae.

What disease is pulmonary bulla

First of all, pulmonary bulla (also called pulmonary bulla) refers to the air sac containing cavity formed in the lung tissue due to the increase of pressure in the alveolar cavity, the rupture and fusion of the alveolar wall due to various reasons. At present, the vast majority of bullae surgery can be completed under video-assisted thoracoscopy (VATS), most of the patients can be significantly improved after surgical treatment.

Then pulmonary bullae are usually secondary to inflammatory lesions of small bronchus, such as pneumonia, tuberculosis or emphysema. There are also some idiopathic pulmonary bullae with unclear etiology. After inflammatory lesions of small bronchus, edema and stenosis appear, and the lumen is partially blocked, resulting in valvular effect, so that the air can enter the alveoli and is not easy to discharge, resulting in increased pressure in the alveoli; at the same time, inflammation damages the lung tissue, and the alveolar wall and septum are gradually broken due to increased pressure in the alveoli, and the alveoli fuse with each other to form a large gasbag containing cavity. Under the microscope, the alveolar walls were flat epithelial cells, sometimes only fibrous membrane or fibrous connective tissue existed.

Finally, the bullae were single or multiple. Secondary to pneumonia or tuberculosis is often single; secondary to emphysema is often multiple, and bullae often with emphysema like changes in lung tissue boundary is not clear. Emphysema with obvious bullae is also called bullous emphysema. If the bullae are not treated in time, it will lead to lung cancer.

matters needing attention

People with pulmonary bullae should not eat stimulating food in life, but eat more fresh fruits and vegetables, and pay attention to bed rest and keep good eating habits. And to pay attention to drink more water, go out to wear masks, do not go to crowded places.
