Pulmonary embolism is occlusion or partial occlusion of the pulmonary artery or its branches by an embolus, usually from the embolization of a blood clot from deep vein thrombosis. [10] It can cause difficulty breathing or chest pain, is usually diagnosed through a CT pulmonary angiography or V/Q scan , and is often treated with anticoagulants ...
A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1] [2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment.
The secondary pulmonary lobule is likely to be made up of between 30 and 50 primary lobules. [30] The lobule is supplied by a terminal bronchiole that branches into respiratory bronchioles. The respiratory bronchioles supply the alveoli in each acinus and is accompanied by a pulmonary artery branch. Each lobule is enclosed by an interlobular ...
The ascending aorta is covered at its commencement by the trunk of the pulmonary artery and the right auricula, and, higher up, is separated from the sternum by the pericardium, the right pleura, the anterior margin of the right lung, some loose areolar tissue, and the remains of the thymus; posteriorly, it rests upon the left atrium and right ...
Bronchial artery is considered dilated when its diameter is more than 2 mm. Several causes of bronchial artery dilatations are: congenital heart or lung diseases, obstructions of pulmonary artery, and lung inflammation. [1] The bronchial arteries are typically enlarged and tortuous in chronic pulmonary thromboembolic hypertension. [3]
The main pulmonary trunk divides into the left and the right pulmonary artery. Pulmonary artery agenesis refers to the absence of one or both pulmonary arteries. Pulmonary artery agenesis refers to a rare congenital absence of pulmonary artery due to a malformation in the sixth aortic arch. It can occur bilaterally, with both left and right ...
