Detailed explanation-1: -Vascular engorgement with erosion is another mechanism of hemoptysis. This occurs within the bronchial capillaries in the mucosa of the tracheobronchial tree as a result of acute infection such as viral or bacterial bronchitis, chronic infection such as bronchiectasis, or a toxic exposure such as cigarette smoke.
Detailed explanation-2: -The lungs have a dual blood supply from the pulmonary arteries and the bronchial arteries. The latter arise as a rule from the aorta and are the source of 90% of the cases of hemoptysis.
Detailed explanation-3: -Inflammation of the tracheobronchial tree renders airways congested, friable, and therefore susceptible to bleeding. Chronic respiratory tract infections lead to an increase in systemic arterial flow via formation of new vessels, which in turn are prone to rupture and cause haemoptysis [27].
Detailed explanation-4: -The most common causes of non-life-threatening hemoptysis in developed countries are acute bronchitis, bronchiectasis, and bronchial neoplasms (primary or secondary) [1-6].
