Right middle lobe bronchiectasis

Lungs are the main part of the human respiratory system, and their health is closely related to people's daily breathing. Right middle lobe bronchiectasis is a branch manifestation of right middle lobe syndrome. Its cause is ultimately due to problems with the bronchus, but whether it is a lesion in the bronchus itself or compression requires diagnosis to determine. Patients with right middle lobe bronchiectasis will experience frequent coughing, and the treatment process will be relatively slow.

Right middle lobe syndrome refers to a general term for a type of disease that is caused by bronchial lesions or external compression and obstruction, resulting in right middle lobe atelectasis, lung shrinkage, or concurrent inflammation and consolidation. The specific cause of the obstruction still needs to be further identified. Clinical manifestations include repeated coughing, coughing up mucus or purulent sputum, and sometimes coughing up blood or fever, which are symptoms of chronic bronchitis or bronchiectasis with infection.

symptom

1. Repeated coughing, sputum, hemoptysis, fever, chest pain, and sometimes a few moist rales can be heard in the right chest.

2. Chest X-ray examination can be performed in the posteroanterior, right lateral and anterior arch positions, which can show a triangular shadow of increased density in the middle lobe area.

3. Bronchography and bronchoscopy are helpful in diagnosing the cause.

Treatment principles

1. Etiological treatment (antibiotics, anti-tuberculosis and chemotherapy drugs, etc., refer to relevant chapters according to the cause of the disease).

2. Surgical treatment.

3. Radiation therapy.

4. Provide symptomatic supportive treatment.

Efficacy evaluation

1. Cure: Clinical symptoms disappear, the right middle lobe of the lung re-expands, and the cause of the disease is eliminated.

2. Improvement: Clinical symptoms improved and the right middle lobe partially expanded.

3. Not cured: symptoms and signs have not improved, the middle lobe has not expanded, and the cause has not been cured.

The causes of this syndrome include inflammation, tuberculosis, tumor, bronchiectasis, foreign body obstruction, etc. Relevant examinations should be carried out as soon as possible to identify the cause and receive early treatment targeted at the cause. The prognosis depends on the cause. Caseous pneumonia: It is more common in patients with reduced body resistance and high allergy to tuberculosis bacteria. A large number of tuberculosis bacteria invade the lung tissue and quickly cause caseous necrotic changes. X-ray manifestations: consolidation of one lung segment or lobe with uneven density and a contour similar to lobar pneumonia, but the density is higher than that of lobar pneumonia. It often occurs in the right upper lobe of the lung. When using high-voltage radiography or tomography, there are multiple irregular worm-eaten cavities. This lobe is often partially collapsed due to fibrosis. The remaining lung fields may be accompanied by bronchial dissemination, forming mostly scattered lobular caseous pneumonia.
