Increased vascular bundles in the bronchial bundles of both lungs are seen in bilateral lower lung fallopian infections as well as alveolar stasis and chronic obstructive pulmonary disease, resulting in pulmonary fibrosis and bronchodilatation and other changes. Increased vascular bundles in the bronchial bundles of both lungs are seen in long-term bedridden pulmonary crush effects, especially in the elderly with repeated pulmonary infections, who are prone to increased texture in both lower lungs with thickened vascular bundles. It is generally prone to pulmonary heart disease, heart failure, and respiratory failure, and even includes pulmonary thromboembolic signs. Therefore, if chest CT indicates increased bronchial vascular bundles in both lungs, it is necessary to further define whether the infection is chronic respiratory or secondary to cardiovascular pathology in order to provide targeted treatment. Clinically, turning and back patting are often given to promote blood circulation in order to reduce the further development of vascular bundle thickening in both lower lungs.
