Increased bronchial vascular bundles in both lungs, usually found during chest X-ray or CT imaging, can be seen in chronic bronchitis, bronchiectasis and other diseases, and need to be treated according to the cause of the disease and analyze the specific problems. 1. Chronic bronchitis: If the above changes are caused by chronic bronchitis, such as coughing up phlegm symptoms, you can use aminoglutethimide, bromhexine and other phlegm drugs to promote phlegm expulsion. If bronchospasm occurs, drugs such as aminophylline can be used to relieve symptoms. If the disease progresses to chronic obstructive pulmonary disease (COPD), it can be treated with long-term inhalation of bronchodilators such as tiotropium bromide. 2. Bronchodilatation: If it is caused by bronchodilatation, attention should be paid to keep warm to avoid recurrent infections and aggravation of the condition. Generally, drugs such as acetylcysteine can be used to dissolve sputum. If there are symptoms of infection such as increased sputum volume or purulent components, antibiotics such as ceftazidime and cefuroxime can be used for treatment. It can also be caused by other diseases that lead to increased vascular bundles in the bronchial tubes of both lungs. It is recommended to consult a doctor in time to clarify the cause of the disease, and to choose the appropriate treatment plan after the doctor’s comprehensive assessment of the disease.
