常见问题

What is the subsegmental pulmonary artery?
The subsegmental pulmonary artery is a branch of the segmental pulmonary artery that is involved in supplying deoxygenated blood to a smaller subsegment of the lung for gas exchange at the alveolar level.
Where is the subsegmental pulmonary artery located?
Subsegmental pulmonary arteries are located within the lung parenchyma, arising from the segmental pulmonary arteries and coursing alongside the subsegmental bronchi into smaller subdivisions of each pulmonary lobe.
What is the function of the subsegmental pulmonary artery?
The subsegmental pulmonary artery is involved in delivering deoxygenated blood from the right side of the heart to the pulmonary capillaries of a specific lung subsegment, where oxygen uptake and carbon dioxide release take place.
What conditions may be associated with the subsegmental pulmonary artery?
Subsegmental pulmonary embolism, pulmonary arterial hypertension, lung infarction, or structural lung diseases such as emphysema may be associated with changes involving the subsegmental pulmonary arteries.
How is the subsegmental pulmonary artery examined?
Subsegmental pulmonary arteries may be assessed through CT pulmonary angiography, which can visualize filling defects suggestive of embolism, ventilation-perfusion scintigraphy, or pulmonary angiography in select clinical settings.
