Hemoptysis (band): Hemoptysis is an American extreme metal band, named after the medical term for the coughing up of blood.Hemoptysis Founded in 2007, the band's music is built around a solid core of old-school thrash/death metal.Bronchial artery: In human anatomy, the bronchial arteries supply the lungs with nutrition and oxygenated blood. Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung.Endobronchial valve: An endobronchial valve is an implantable medical deviceā€”a small, one-way valve, which is implanted in an airway in the pulmonary system to treat one of several lung conditions. The one-way endobronchial valve is typically implanted such that when a patient exhales, air is able to flow through the valve and out of the lung compartment that is fed by that airway, but when the patient inhales, the valve closes and blocks air from entering that lung compartment.Bronchopleural fistula: A bronchopleural fistula (BPF) is a fistula between the pleural space and the lung. It sometimes develops following pneumonectomy or an infection.BronchiectasisLung abscessLung cancer surgery: Lung cancer surgery describes the use of surgical operations in the treatment of lung cancer. It involves the surgical excision of cancer tissue from the lung.Tracheal tumorChronic lung diseaseHemosiderosis: Hemosiderosis (AmE) or haemosiderosis (BrE) is a form of iron overload disorder resulting in the accumulation of hemosiderin.Gross examinationDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.HemothoraxPolyvinyl alcohol
