Hemoptysis: Expectoration or spitting of blood originating from any part of the RESPIRATORY TRACT, usually from hemorrhage in the lung parenchyma (PULMONARY ALVEOLI) and the BRONCHIAL ARTERIES.Bronchial Arteries: Left bronchial arteries arise from the thoracic aorta, the right from the first aortic intercostal or the upper left bronchial artery; they supply the bronchi and the lower trachea.Bronchoscopy: Endoscopic examination, therapy or surgery of the bronchi.Bronchial Fistula: An abnormal passage or communication between a bronchus and another part of the body.Bronchiectasis: Persistent abnormal dilatation of the bronchi.Lung Abscess: Solitary or multiple collections of PUS within the lung parenchyma as a result of infection by bacteria, protozoa, or other agents.Bronchial DiseasesEmbolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.Bronchial Neoplasms: Tumors or cancer of the BRONCHI.Pneumonectomy: The excision of lung tissue including partial or total lung lobectomy.Pulmonary Aspergillosis: Infections of the respiratory tract with fungi of the genus ASPERGILLUS. Infections may result in allergic reaction (ALLERGIC BRONCHOPULMONARY ASPERGILLOSIS), colonization in pulmonary cavities as fungus balls (MYCETOMA), or lead to invasion of the lung parenchyma (INVASIVE PULMONARY ASPERGILLOSIS).Tracheal NeoplasmsLung Diseases: Pathological processes involving any part of the LUNG.Hemosiderosis: Conditions in which there is a generalized increase in the iron stores of body tissues, particularly of liver and the MONONUCLEAR PHAGOCYTE SYSTEM, without demonstrable tissue damage. The name refers to the presence of stainable iron in the tissue in the form of hemosiderin.Lung Diseases, Fungal: Pulmonary diseases caused by fungal infections, usually through hematogenous spread.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Hemothorax: Hemorrhage within the pleural cavity.Polyvinyl Alcohol: A polymer prepared from polyvinyl acetates by replacement of the acetate groups with hydroxyl groups. It is used as a pharmaceutic aid and ophthalmic lubricant as well as in the manufacture of surface coatings artificial sponges, cosmetics, and other products.Radiography, Thoracic: X-ray visualization of the chest and organs of the thoracic cavity. It is not restricted to visualization of the lungs.
