| cystic adenomatoid malformation of lung | <radiology> Only true pulmonary cystic disease of newborn, three X-ray types: multicystic, walls of varying thickness, multicystic, one large dominant thin-walled cyst, solid, mediastinal shift common, cysts often contain foetal lung fluid, Treatment: surgery Cf: congenital lobar emphysema (12 Dec 1998) |
|---|---|
| cystic adenomatoid malformation of lung, congenital | A developmental anomaly that usually becomes apparent in the neonatal period with progressive respiratory distress. This malformation is a focal pulmonary dysplasia characterised by a multicystic mass of terminal bronchiolar structures. Ccam is classified into 3 separate types (I, II, III) depending on cyst size. (12 Dec 1998) |
| heart and lung transplant | A surgical procedure which replaces a diseased heart and lungs with a healthy heart and lungs from a donor. They have been used in patients with primary pulmonary hypertension and isolated severe heart and lung disease. They are not recommended for those with associated systemic disorders such as diabetes or autoimmune illness. Those with liver and/or kidney disease are also not candidates. Long-term outcomes are still being studied. (27 Sep 1997) |
| heart-lung machine | A combination blood pump and blood oxygenator used for temporary periods of time in cardiopulmonary bypass for cardiac surgery. (12 Dec 1998) |
| heart-lung transplantation | The simultaneous, or near simultaneous, transference of heart and lungs from one human or animal to another. (12 Dec 1998) |
| hilum of lung | A wedge-shaped depression on the mediastinal surface of each lung, where the bronchus, blood vessels, nerves, and lymphatics enter or leave the viscus. Synonym: hilum pulmonis, porta pulmonis. (05 Mar 2000) |
| secondary lung cancer | The spread of cancerous tumours from a distant organ to the lung. Due to the lungs tremendous blood and lymphatic supply it is a frequent site for metastatic cancer. Cancers which commonly metastasize to the lung include osteosarcoma, breast cancer, neuroblastoma, Wilm's tumour and non-Hodgkin's lymphomas. (27 Sep 1997) |
| honeycomb lung | <radiology> Mnemonic: honey and SPICE, sarcoid, pneumoconiosis, interstitial fibrosis, collagen-vascular disease, eosinophilic granuloma, ** see also: interstitial lung disease, honeycombing (12 Dec 1998) |
| pump lung | In shock, the development of oedema, impaired perfusion, and reduction in alveolar space so that the alveoli collapse. Synonym: pump lung, wet lung, white lung. (05 Mar 2000) |
| horizontal fissure of right lung | The deep fissure that separates the upper and middle lobes of the right lung. Synonym: fissura horizontalis pulmonis dextri, horizontal fissure of right lung, minor fissure. (05 Mar 2000) |
| human embryo lung cell | <cell culture> Diploid, untransformed cells from the lungs of human embryos which are used to make vaccines against certain viruses (such as rabies). (09 Oct 1997) |
| shock lung | In shock, the development of oedema, impaired perfusion, and reduction in alveolar space so that the alveoli collapse. Synonym: pump lung, wet lung, white lung. (05 Mar 2000) |
| hyperlucent lung | The radiographic finding that a lung or portion thereof is less dense than normal, as from air trapping by a bronchial foreign body, asymmetric emphysema, or decreasing blood flow. See: unilateral hyperlucent lung. (05 Mar 2000) |
| silo-filler's lung | Pulmonary oedema, usually delayed for 1-4 hours, occurring in an individual exposed to silage, probably due to nitrogen dioxide; can progress to bronchiolitis obliterans. (05 Mar 2000) |
| small cell lung cancer | A type of lung cancer in which the cells are small and round. Also called oat cell lung cancer. (12 Dec 1998) |
