Definition of Thromboembolism

Thromboembolism: Formation in a blood vessel of a clot (thrombus) that breaks loose and is carried by the blood stream to plug another vessel. The clot may plug a vessel in the lungs (pulmonary embolism), brain (stroke), gastrointestinal tract, kidneys, or leg. Thromboembolism is an important cause of morbidity (disease) and mortality (death), especially in adults. Treatment may involve anticoagulants (bloodthinners), aspirin, or vasodilators (drugs that relax and widen vessels).
