| pulmonary alveolar proteinosis | <radiology> Overproduction of surfactant which can lead to alveolar (end-air-space) filling, peak age: 20 - 50 yrs, 33% asymptomatic, treatment: lavage Findings: bat-wing alveolar infiltrate, no interstitial disease, no adenopathy (12 Dec 1998) |
|---|---|
| pulmonary alveoli | Small polyhedral outpouchings along the walls of the alveolar sacs, alveolar ducts and terminal bronchioles through the walls of which gas exchange between alveolar air and pulmonary capillary blood takes place. (12 Dec 1998) |
| pulmonary alveolus | One of the thin-walled saclike terminal dilations of the respiratory bronchioles, alveolar ducts, and alveolar sacs across which gas exchange occurs between alveolar air and the pulmonary capillaries. Synonym: alveoli pulmonis, alveolus, air cells, air vesicles, bronchic cells. (05 Mar 2000) |
| pulmonary amoebiasis | Infection of the lung by amoebae; usually indicates extension of Entamoeba histolytica infection from abscess of liver, penetrating through the diaphragm into the lung. (05 Mar 2000) |
| pulmonary angiogram | <investigation, radiology> A diagnostic procedure which involves the injection of a radiopaque substance into the pulmonary artery to highlight its course on X-ray. Pulmonary embolism can be accurately diagnosed using this procedure. (15 Dec 1997) |
| pulmonary anthrax | A form of anthrax acquired by inhalation of dust containing Bacillus anthracis; there is an initial chill followed by pain in the back and legs, rapid respiration, dyspnea, cough, fever, rapid pulse, and extreme cardiovascular collapse. Synonym: anthrax pneumonia, ragpicker's disease, ragsorter's disease, rag-sorter's disease, wool-sorter's pneumonia, woolsorter's disease, wool-sorter's disease. (05 Mar 2000) |
| pulmonary arc | An obsolete term for pulmonary salient. (05 Mar 2000) |
| pulmonary area | The region of the chest at the second left intercostal space, where sounds produced at the pulmonary valve of the right ventricle are heard most distinctly. (05 Mar 2000) |
| pulmonary arteries | <anatomy> The pulmonary arteries deliver deoxygenated blood from the right ventricle to the lungs. They are the only arteries in the human body that carry deoxygenated blood. (27 Sep 1997) |
| pulmonary artery | <anatomy, artery> The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs. (12 Dec 1998) |
| pulmonary artery aneurysm | Aneurysm of the pulmonary artery; rare in the absence of congenital heart disease. (05 Mar 2000) |
| pulmonary artery banding | A surgical method of decreasing pulmonary blood flow and thereby volume overload of the left ventricle, alleviating CHF in certain congenital heart defects. (05 Mar 2000) |
| pulmonary artery sarcoma | <radiology> Rare, age: 21 - 80 (most common: 45 - 55), usual presentation: hilar mass or hilar infiltrative lesion, other findings: decreased vascular markings, atelectasis / volume loss, metastatic nodules, decreased or absent perfusion on V/Q, intravascular soft-tissue mass on CT (12 Dec 1998) |
| pulmonary aspergillosis | An inflammatory and destructive disease of the bronchi and lungs due to the presence and growth of Aspergillus fumigatus. There are four varieties: 1) a bronchial infection with allergic manifestations, in which the fungus grows in the mucus (evoked by the inflammation), which may be expectorated as yellow bronchial casts and may cause intermittent bronchial obstruction, with transient pulmonary shadows seen radiographically; asthma is often present, and bronchial wall destruction may eventually result in a proximal form of bronchiectasis; 2) aspergilloma; 3) an infection with pulmonary necrosis as a pneumonic involvement of the lung in debilitated subjects; 4) disseminated aspergillosis. Synonym: bronchopneumonic aspergillosis, pulmonary aspergillosis. Disseminated aspergillosis, a variety of bronchopulmonary aspergillosis, characterised by a generalised infection of the lung with Aspergillus occurring usually in subjects with defective immune response. Invasive aspergillosis, so-called because of the peculiar predilection of Aspergillus fumigatus to invade blood vessels and cause tissue infarction; it is second only to candidiasis as a cause of opportunistic fungal infection in patients whose immune mechanisms have been suppressed by chemotherapy. (05 Mar 2000) |
| pulmonary atresia | Congenital absence of the normal valvular orifice into the pulmonary artery. This condition is characterised by cardiomegaly, reduced pulmonary vascularity, and right ventricular atrophy. (12 Dec 1998) |
