| 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) |
| air embolism | <physiology> A serious condition that results when air (in the form of bubbles) invades the blood vessels causing disruption of normal blood flow. (06 Aug 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| arterial embolism | <cardiology, physiology> A sudden interruption in arterial blood flow to an organ or body part (extremity). The blockage is caused by a blot clot or atherosclerotic plaque that has moved through the arterial circulation from one position to another. The resulting mechanism is the same regardless of cause or location. Oxygen deprivation to the tissues distal to the occlusion become ischaemic and die (necrosis). Atrial fibrillation is a risk factor for arterial embolism due to the release of blood clots from the fibrillating heart. Blood vessel injury and increased levels of platelets can also be a risk for arterial embolism. Symptoms vary with location, but pain, coolness to an extremity and a absent or diminished pulse are common in the case of an extremity embolism. Treatment is often surgical or involves the use of blood clot dissolving medications (for example streptokinase) delivered selectively to the site of the blockage. (17 Oct 1997) |
| atheroma embolism | 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. Synonym: atheroma embolism. (05 Mar 2000) |
| bland embolism | Embolism by simple nonseptic material. (05 Mar 2000) |
| bone marrow embolism | Obstruction of a vessel by bone marrow, usually following fracture of a bone. (05 Mar 2000) |
| gas embolism | <physiology> A serious condition that results when air (in the form of bubbles) invades the blood vessels causing disruption of normal blood flow. (06 Aug 1998) |
| pantaloon embolism | Synonym: saddle embolism. (05 Mar 2000) |
| paradoxical embolism | 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) |
| venous embolism | Embolism of a vein by an embolus carried in a direction opposite to that of the normal blood current, after being diverted into a smaller vein. Synonym: venous embolism. (05 Mar 2000) |
