| superior branch of the right and left inferior pulmonary veins | Tributaries of the right and left inferior pulmonary veins which receive oxygenated blood from the superior [S6] bronchopulmonary segments of the inferior lobes of the right and left lungs. Synonym: ramus superior venae pulmonalis dextrae/sinistrae inferioris. (05 Mar 2000) |
| superior lingular branch of lingular branch of superior lobar left pulmonary artery | <anatomy, artery> Branch (of the lingular branch) of the left pulmonary artery serving the superior lingular segment of the superior lobe of the left lung. Synonym: ramus lingularis superior. (05 Mar 2000) |
| superior part of lingular branch of left pulmonary vein | <anatomy, vein> The vein that drains the superior lingular bronchopulmonary segment of the left lung. Synonym: pars superior rami lingularis venae pulmonis sinistri. (05 Mar 2000) |
| superior pulmonary sulcus tumour | <oncology, tumour> Tumour originating from the superior sulcus of the lung that invades all or a portion of the brachial plexus. (16 Dec 1997) |
| diffuse interstitial pulmonary fibrosis | This represents a group of pulmonary disorders (lower respiratory tract) that leads to a functional loss in the alveolar air sacs and a compromise in the diffusion of oxygen from air to blood. There is widespread inflammation and scar tissue (fibrosis) formation within the lung. The causes are varied and include: inorganic and organic dusts, gases, fumes, vapors, infections, radiation, medications, coal dust, silicosis and byssinosis. When the cause is not identifiable it is referred to as idiopathic diffuse interstitial pulmonary fibrosis (27 Sep 1997) |
| diffuse pulmonary haemorrhage | <radiology> Thrombocytopenia, coagulopathy, idiopathic pulmonary haemosiderosis, Goodpasture syndrome, systemic lupus erythematosus, Wegeners granulomatosis, polyarteritis nodosa, Henoch-Schonlein purpura, Behcet disease, D-penicillamine, lymphangiography (12 Dec 1998) |
| idiopathic pulmonary fibrosis | <radiology> Aka: usual interstitial pneumonia (UIP), 5-6th decade; M:F = 1:1, clubbing of fingers (83%), lymphocytosis on lavage, increased occurence of bronchogenic CA, average survival of 4-6 years; 87% mortality CXR findings: occasional ground glass pattern in early stage of alveolitis, diffuse reticulations (60%) predominantly at bases, honeycombing, pleural effusion (4%); pleural thickening (6%), pneumothorax in 7% (late stage), progressive volume loss see: interstitial pulmonary fibrosis (12 Dec 1998) |
| idiopathic pulmonary haemosiderosis | <chest medicine> A rare, sporadic, fatal, mostly in children with an equal sex distribution. The condition also occurs in adults where there is a sex difference (M:F = 2:1). The patients present with recurrent attacks of pulmonary haemorrhage, acute phase: bat-wing alveolar infiltrates, clears rapidly, chronic findings: haemosiderosis, pulmonary fibrosis, cor pulmonale. (12 Dec 1998) |
| idiopathic pulmonary hypertension | <chest medicine> 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) |
| inferior lingular branch of lingular branch of left pulmonary artery | <anatomy, artery> Branch (of the lingular branch) of the left pulmonary artery serving the inferior lingular segment of the superior lobe of the left lung. Synonym: ramus lingularis inferior. (05 Mar 2000) |
| inferior part of lingular branch of left pulmonary vein | <anatomy, vein> The vein draining the inferior lingular bronchopulmonary segment of the left lung. Synonym: pars inferior rami lingularis. (05 Mar 2000) |
| infralobar part of posterior branch of right pulmonary vein | <anatomy, vein> The vein draining the posterior segment of the right lung that emerges inferior to the superior lobe; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars infralobaris rami posterioris venae pulmonalis dextrae. (05 Mar 2000) |
| intersegmental part of pulmonary vein | A vein receiving blood from adjacent bronchopulmonary segments; it emerges from the inferior margin of a segment to become a tributary of a branch of a pulmonary vein. Synonym: infrasegmental part, intersegmental part of pulmonary vein, pars infrasegmentalis. (05 Mar 2000) |
| interstitial pulmonary fibrosis | <radiology> Idiopathic, idiopathic pulmonary fibrosis (AKA: usual interstitial pneumonitis), Hamman-Rich syndrome (rapidly progressive), drug-related, collagen-vascular disease, rheumatoid lung disease, scleroderma (12 Dec 1998) |
