What causes pulmonary bullae?

Pulmonary bullae refer to the formation of an air-containing sac cavity in the lung tissue due to the increase of pressure in the alveolar cavity due to various reasons, the rupture of the alveolar wall, and the fusion of each other.

Pulmonary bullae are generally secondary to inflammatory lesions of the small bronchi, such as pneumonia, tuberculosis, or emphysema, and there are also some idiopathic bullae that are not clear. After inflammatory lesions occur in the small bronchi, edema, stenosis, and partial blockage of the lumen are partially blocked, which gives birth to valvular effects, so that air can enter the alveoli and is not easy to be discharged, resulting in an increase in the pressure in the alveolar cavity; At the same time, inflammation damages the lung tissue, and the alveolar wall and septum gradually ruptured due to the increase in intravesicular pressure, and the alveoli fuse with each other to form a large air-containing sac cavity. Microscopically, the vesicle wall is an alveolar flat epithelial cell, sometimes with only fibrous membranes or fibrous connective tissue.

Most of the bullae are caused by chronic inflammation, such as bronchitis and other reasons, such as the diagnosis of pulmonary bullae, the smaller ones can consider temporary observation and follow-up, and actively ** bronchitis and other patients, such as large bullae or hemopneumothorax and other complications can be operated on**, according to the specific situation to choose thoracoscopic minimally invasive and other surgical methods, I wish you a good morning**.

The lungs are an important oxygen station in the human body, and if the alveolar function is impaired or destroyed in large quantities, no matter how much oxygen is inhaled, it will not be able to absorb it. In life, two bad habits can cause alveoli and pulmonary fibers. Occupy one and advise you to change it early.

Some people have physiological anatomical abnormalities, while others may develop chronic bronchitis. Don't worry too much about this situation, if there is no infection, generally speaking, avoid heavy physical work, avoid ruptured alveoli and cause pneumothorax, then it is not a big problem.

Bullae refers to bullous emphysema, a type of localized emphysema. Alveoli are highly inflated, and alveolar walls rupture and fuse with each other, usually caused by valve obstruction of the small bronchi. Asymptomatic bullae do not need to be the primary lesion in patients with chronic bronchitis or emphysema.

Antibiotics are given in secondary infections.

The main thing is smoking, as well as second-hand smoke, so it is recommended not to smoke and not to go to places where there is a smell of smoke.

The second is the excessive fatigue of the body, we must have good living habits, do not stay up late, and diet does not have much effect.

Type I bullae with normal parenchyma: they are characterized by bullae located within the parenchyma with well-defined cavities and borders. It is often located at the apex of the lungs.

When the bullae are large, they compress the surrounding lung tissue, but because the lung parenchyma is normal, the patient is relatively asymptomatic and the lung function is still close to normal. Giant alveoli fill one side of the chest.

Type II. Extensive emphysema with bullae with surrounding lung parenchyma: a local exacerbation of extensive emphysema, bullae are often multiple, bilateral, and have a wide base implanted in the lungs, and the size and extent of the bullae often differ, and the symptoms are related not only to the size of the bullae, but also to the severity of the surrounding emphysema.

Damaged lung: diffuse bullous emphysema, which completely deprives the area of the lung parenchyma, usually to the lung segment or lobe, but can also involve one side of the whole lung.

As a doctor, I, you.

1. Pulmonary bullae are generally unknown, which may be caused by genetics, or may be caused by secondary lesions such as secondary tuberculosis, pneumonia, emphysema, etc., which can produce pulmonary bullae.

2. The main operation of pulmonary bullae can be minimally invasive thoracoscopy or thoracotomy.

3. The danger of pulmonary bullae is mainly that it can cause pneumothorax, resulting in sudden dyspnea.

Bar, there are definitions and explanations!! It is a more complex problem, simply put, a small problem in congenital development leads to a large air-containing cavity in the lungs, which is easy to rupture and cause pneumothorax!!

There is nothing wrong with the alveoli being pneumothorax.

Pulmonary bullae disease, mainly manifested as cough, wheezing, chest tightness, angina, and dyspnea, should be actively exercised, drink more water, patients with pulmonary bullae should be carried out in time to avoid delaying the best time, hope that the patient will recover as soon as possible.

Hello, the symptoms of bullae are closely related to the number and size of bullae and whether they are accompanied by underlying lung disease. Smaller, smaller, simpler bullae may be asymptomatic and are sometimes found only incidentally on chest x-ray or CT. Large or multiple bullae may have symptoms such as chest tightness and shortness of breath.

In particular, patients with giant bullae with a volume of more than 1 2 on one side of the chest cavity, or patients with chronic obstructive pulmonary disease often have obvious symptoms such as chest tightness and shortness of breath. Intrabullae infection may present with symptoms of lung infection. A small number of patients with bullae have symptoms such as hemoptysis and chest pain.

Pulmonary signs are often manifestations of pre-existing lung disease.
