Formation in a blood vessel of a clot (thrombus) that breaks loose and is carried by the blood stream to plug another vessel.
Obstruction of a blood vessel by a blood clot, often the result of a clot moving from its site of origin to a smaller vessel, where it causes the obstruction.
A condition in which a blood clot forms in one part of the body and moves through the blood vessels to block another, usually smaller, part.
Condition in which a blood vessel is blocked by an embolus carried in the bloodstream from its site of formation. The area affected by the diminished blood supply may become cyanotic (bluish) and numb. Often the first symptom is excruciating pain. Treatment includes anticoagulants, rest, moist heat, and surgery, especially if a major vessel (aorta, pulmonary artery, femoral or iliac arteries) is involved.
Blockage (embolism) of a blood vessel by a thrombus (blood clot) that has formed elsewhere in the body and has been carried through the bloodstream.
The condition in which a blood clot (thrombus), formed at one point in the circulation, becomes detached and lodges at another point. It is most commonly applied to the association of phlebothrombosis and pulmonary embolism (pulmonary thromboembolic disease).
The formation of a thrombus (blood clot) in one part of the circulatory system from which a portion becomes detached and lodges in another blood vessel, partially or completely obstructing the blood flow (an embolism). Most commonly a thrombus is formed in the veins of the leg — deep vein thrombosis (DVT) — and the embolism lodges in the pulmonary (lung) circulation. Pulmonary embolism is a potentially fatal condition and requires urgent anticoagulant treatment anticoagulants) and sometimes surgery. Extended periods lying in bed or prolonged sitting in a confined position such as a car or aeroplane can cause DVT; venous thromboses in the legs may occur after surgery and preventive anticoagulant treatment with heparin and warfarin is often used. Similar treatment is needed if a thrombus develops. streptokinase is also used to treat thromboembolism.
The blocking of a blood vessel by a clot (or part of a clot) that has broken off from the place where it formed and traveled to another organ.
A blood clot capable of detaching and obstructing a blood vessel in a different location within the body.
Embolism refers to the obstruction of a blood vessel due to a fragment of a blood clot (embolus) that has detached from another clot (thrombus) located elsewhere in the circulatory system.
