| DVT | Deep Vein Thrombosis |
| deep vein thrombosis | Blood clotting in the veins of the inner thigh or leg. In air travel, DVT is the economy-class syndrome. Even in young, health travelers the long stretches immobilised in cramped seats in cabins with very low humidity set the stage for the formation of a thrombus (blood clot) in the lower leg. Blood clots can break off (as an embolism) and makes its way to the luhg where it has the potential of causing respiratory distress and respiratory failure. (12 Dec 1998) |
|---|---|
| deep venous thrombosis | <cardiology> A blood clot that forms in a vein resulting in obstruction of venous flow. most common clinically in the lower extremities. (27 Sep 1997) |
| dilation thrombosis | Thrombosis due to slowed circulation consequent upon dilation of a vein. (05 Mar 2000) |
| thrombosis | <haematology> The formation, development or presence of a thrombus. (14 May 1997) |
| effort-induced thrombosis | <syndrome> Stress thrombosis or spontaneous thrombosis of the subclavian or axillary vein; a thoracic-outlet syndrome. Synonym: effort-induced thrombosis. (05 Mar 2000) |
| embolism and thrombosis | A collective term for diseases characterised by the formation, development, or presence of a thrombus (thrombosis) and the blocking of a vessel by the thrombus brought to its site by the blood current (embolism). (12 Dec 1998) |
| acute pulmonary alveolitis | Acute inflammation involving exudate into the pulmonary alveoli and impaired gas exchange; may result in necrosis with haemorrhage into the lungs; occurs in Goodpasture's syndrome, in association with a glomerulonephritis. (05 Mar 2000) |
| acute pulmonary eosinophilia | <chest medicine> A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| adenomatosis, pulmonary | A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells. It is characterised by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (12 Dec 1998) |
| apical branch of inferior lobar branch of right pulmonary artery | <anatomy, artery> Branch (of the inferior lobar branch) of the right pulmonary artery serving the apical segment of the inferior lobe of the right lung. Synonym: ramus apicalis lobi inferioris arteriae pulmonalis dextrae. (05 Mar 2000) |
| apicoposterior branch of left superior pulmonary vein | <anatomy, vein> Drains apicoposterior bronchopulmonary segment of superior lobe of left lung. Synonym: ramus apicoposterior venae pulmonalis sinistrae superioris. (05 Mar 2000) |
| basal part of pulmonary artery | <anatomy, artery> See: right pulmonary artery, left pulmonary artery. (05 Mar 2000) |
| bifurcation of pulmonary trunk | The division of the pulmonary trunk into right and left pulmonary arteries. Synonym: bifurcatio trunci pulmonalis. (05 Mar 2000) |
| valve of pulmonary trunk | <anatomy, cardiology> The heart valve that divides the right ventricle and the pulmonary artery. The pulmonic valve opens when the right ventricle contracts allowing blood to flow into the pulmonary artery. The pulmonic valve on closure prohibits the backwash of unoxygenated blood into the right ventricle. The pulmonic valve has 3 valve cusps. (27 Sep 1997) |
| vein, pulmonary | One of four vessels that carry aerated blood from the lungs to the right atrium of the heart. (the four are the right and left superior and inferior pulmonary veins). The pulmonary veins are the only veins that carry bright red oxygenated blood. (12 Dec 1998) |
