bronchial artery การใช้

• With modern surgical techniques, bronchial anastomoses heal well without bronchial artery reconnection.
• The bronchial veins are counterparts to the bronchial arteries.
• However, they only carry ~ 13 % of the blood flow of the bronchial arteries.
• In contrast to the " pulmonary arteries ", the bronchial arteries supply nutrition to the lungs themselves.
• Note that much of the oxygenated blood supplied by the bronchial arteries is returned via the pulmonary veins rather than the bronchial veins.
• In bronchial artery embolization for treatment of massive hemoptysis, one of the most serious complications is inadvertent occlusion of the artery of Adamkiewicz.
• Even when the pulmonary aneurysm is present, the actual bronchial bleeding may be from the bronchial artery, rather than from the pulmonary artery.
• Largely for this reason, bronchial artery circulation is usually sacrificed during lung transplants, instead relying on the persistence of a microcirculation presumably arising from the deoxygenated pulmonary circulation to provide perfusion to the airways.
• Small physiological, or " normal ", shunts are seen due to the return of bronchial artery blood and coronary blood through the Thebesian veins, which is deoxygenated, to the left side of the heart.
• The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph nodes, and areolar tissue, all of which are enclosed by a reflection of the pleura.
• My question is : if the embolism is stuck in the pulmonary artery ( this is the definition of PE ) how can influence on the bronchial arteries which are exploded as a result of the higher pressure of the blood there and causes to hemoptysis . here is the higher pressure is found before the embolism rather than after this point of this embolism is found.
