| congenital pulmonary arteriovenous fistula | Abnormal congenital communication between pulmonary arteries and veins usually found in the lung parenchyma. (05 Mar 2000) |
|---|---|
| plexogenic pulmonary arteriopathy | <syndrome> Sclerosis of the pulmonary arteries in chronic cor pulmonale; associated with severe cyanosis, it is a condition resembling polycythemia vera but resulting from primary pulmonary arteriosclerosis or primary pulmonary hypertension and characterised by plexiform lesions of arterioles. Synonym: Ayerza's disease, cardiopathia nigra, plexogenic pulmonary arteriopathy. (05 Mar 2000) |
| postcapillary pulmonary hypertension | <radiology> Heart: LV failure, mitral stenosis, LA myxoma / thrombus, cor triatriatum, Pulmonary veins: congenital stenosis of pulmonary vein origin, mediastinal granulomata and neoplasms, idiopathic pulmonary veno-occlusive disease, anomalous pulmonary venous return (12 Dec 1998) |
| posterior branch of right superior pulmonary vein | <anatomy, vein> Drains posterior portion of superior lobe of right lung. Synonym: ramus posterior venae pulmonalis dextrae superioris. (05 Mar 2000) |
| precapillary pulmonary hypertension | <radiology> Vascular: increased flow (left to right shunts), decreased flow (tetralogy of Fallot), primary pulmonary hypertension, thromboembolic disease, pulmonary arteritides, Pleuropulmonary: emphysema, diffuse lung disease, fibrothorax, chest deformity, hypoventilation, high-altitude pulmonary hypertension (12 Dec 1998) |
| hantavirus pulmonary syndrome | <syndrome> Acute respiratory illness in humans caused by the muerto canyon virus whose primary rodent reservoir is the deer mouse peromyscus maniculatus. First identified in the southwestern united states, this syndrome is characterised most commonly by fever, myalgias, headache, cough, and rapid respiratory failure. (12 Dec 1998) |
| primary pulmonary hypertension | A condition where there is increased blood pressure in the pulmonary arteries with otherwise normal heart and lungs. The cause is unknown, but there is diffuse narrowing of the pulmonary arteries resulting in increased arteriolar pressures. Secondary heart failure ensues without correction of this problem. There is an increased incidence of this disease in females between the ages of 20 and 40 years. Treatment may include a heart and lung transplant in select cases. (27 Sep 1997) |
| primary pulmonary lobule | The part of the airway consisting of a respiratory bronchiole and all of its branches. Synonym: primary pulmonary lobule, respiratory lobule. (05 Mar 2000) |
| sarcoidosis, pulmonary | Sarcoidosis affecting predominantly the lungs, the site most frequently involved and most commonly causing morbidity and mortality in sarcoidosis. Pulmonary sarcoidosis is characterised by sharply circumscribed granulomas in the alveolar, bronchial, and vascular walls, composed of tightly packed cells derived from the mononuclear phagocyte system. The clinical symptoms when present are dyspnea upon exertion, nonproductive cough, and wheezing. (cecil textbook of medicine, 19th ed, p431) (12 Dec 1998) |
| high altitude pulmonary oedema | <physiology> The abnormal deposition of fluid into the lungs that occurs with exposure to lower barometric pressure and low oxygen. (12 Jan 1998) |
| secondary pulmonary lobule | A pyramidal mass of lung tissue whose sides are bounded by the incomplete interlobular connective tissue septa and whose base, which is 1 to 2 cm in diameter, usually faces the pleural surface of the lung; lobule's that occupy a more central position in the lung are not well defined and are considered to consist of three to five pulmonary acini with proximate terminal bronchioles. (05 Mar 2000) |
| pulmonary | <anatomy, chest medicine> Pertaining to the lungs. Origin: L. Pulmonarius (06 Oct 1997) |
| pulmonary acariasis | Infestation of the lungs of monkeys with the mite, Pneumonyssus simicola. (05 Mar 2000) |
| pulmonary acinus | The part of the airway consisting of a respiratory bronchiole and all of its branches. Synonym: primary pulmonary lobule, respiratory lobule. (05 Mar 2000) |
| pulmonary adenomatosis | A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells; characterised by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (05 Mar 2000) |
