| pulmonary embolism | <cardiology> The lodgment of a blood clot in the lumen of a pulmonary artery, causing a severe dysfunction in respiratory function. Pulmonary emboli often have origin in the veins of the lower extremities where clots form in the deep leg veins and then travel to the lungs via the venous circulation. Symptoms and features include acute onset of shortness of breath, chest pain (worse with breathing) and rapid heart rate and respiratory rate. Some individuals may have haemoptysis. Diagnosis can be made on a ventilation perfusion scan of the lung or on a pulmonary angiogram. (15 Dec 1997) |

| pulmonary embolism: findings | <radiology> Embolism without infarction (90%), normal chest (25%), platelike atelactasis, Westermark sign, knuckle sign, local widening of artery by impacted embolus, segmental / lobar consolidation, pleural effusion embolism with infarction (10%), wedge-shaped consolidation (50%), may cavitate, Hampton hump, pleural effusion (50%), no air-bronchogram, melting sign, Fleischner lines, platelike atelactasis (25%), cardiomegaly / congestive heart failure (20%), elevated hemidiaphragm (20%) see: pulmonary embolism (12 Dec 1998) |
| pyaemic embolism | Plugging of an artery by an embolus detached from a suppurating thrombus. Synonym: infective embolism. (05 Mar 2000) |
| straddling embolism | Embolism occurring at the bifurcation of an artery and blocking more or less completely both branches. Synonym: riding embolism. (05 Mar 2000) |
| direct embolism | Embolism occurring in the direction of the blood current. (05 Mar 2000) |
| infective embolism | Plugging of an artery by an embolus detached from a suppurating thrombus. Synonym: infective embolism. (05 Mar 2000) |
| obturating embolism | Complete closing of the lumen of a vessel by an embolism. (05 Mar 2000) |
| oil embolism | <orthopaedics> The occurrence of fat globules in the bloodstream following fracture of a long bone, in burns, in childbirth or in association with fatty degeneration of the liver. Symptoms occur when fat globules block vessels within the lung (i.e. Pulmonary embolism) or the cerebral vasculature (i.e. Stroke). Fat embolism after bone fracture generally occurs in the first 3-4 days post fracture and commonly manifests with the signs and symptoms of pulmonary embolism. (27 Sep 1997) |
| embolism | <cardiology, physiology> The sudden blocking of an artery by a clot or foreign material which has been brought to its site of lodgment by the blood current. Origin: L. Embolismus, from Gr. Ballein = to throw (18 Nov 1997) |
| embolism, air | Embolism due to air bubbles entering the blood vessels after trauma, surgical procedures, or changes in atmospheric pressure. (12 Dec 1998) |
| embolism, amniotic fluid | Embolism caused by strong uterine contractions near the end of a normal pregnancy that force amniotic fluid into the maternal circulation. (12 Dec 1998) |
| 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) |
| embolism, cholesterol | An embolism of lipid debris from an ulcerated atheromatous deposit, generally from a large artery to small arterial branches. It is usually small and rarely causes infarction. (12 Dec 1998) |
| embolism, fat | Embolism caused by fat entering the circulation. It is often seen after fractures of large bones or after corticosteriod administration. (12 Dec 1998) |
| embolism, paradoxical | Passage of a clot (thrombus) from a vein to an artery. When clots in veins break off (embolise) , they travel first to the right side of the heart and, normally, then to the lungs where they lodge. The lungs act as a filter to prevent the clots from entering the arterial circulation. However, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism. Once in the arterial circulation, a clot can travel to the brain, block a vessel there, and cause a stroke (cerebrovascular accident). Because of the risk of stroke from paradoxical embolism, it is usually recommended that even small atrial septal defects be repaired. Also called crossed embolism. (12 Dec 1998) |
