A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency medicine: Symptoms
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. [1] [2] Thrombosis may occur in veins (venous thrombosis) or in arteries (arterial thrombosis).
Lung infarction or pulmonary infarction occurs when an artery to the lung becomes blocked and part of the lung dies. [1] It is most often caused by a pulmonary embolism . Because of the dual blood supply to the lungs from both the bronchial circulation and the pulmonary circulation , this tissue is more resistant to infarction .
Pulmonary embolism is the third leading cause of death from cardiovascular disease and happens when blood clots block an artery in the lungs, so blood and gas cannot flow normally.
Typically, blood clots develop in the deep veins of the lower extremities, deep vein thrombosis (DVT) or as a blood clot in the lung, pulmonary embolism. A very small number of people who develop blood clots have a more serious and often life-threatening condition, known as thrombotic storm (TS). TS is characterized by the development of more ...

Mycobacterium avium complex (MAC) is the most common cause of NTM lung disease in most countries, including the United States. [6] Classically, MAC infection results in either upper lobe cavities in male smokers with COPD or bronchiectasis in thin, older women; however, it is possible to have both cavities and bronchiectasis in the same patient ...
