Thromboembolism
Thromboembolism is the combination of thrombosis and its main complication, embolism. Thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets and fibrin to form a blood clot to prevent blood loss. Alternatively, even when a blood vessel is not injured, blood clots may form in the body if the proper conditions present themselves. If the clotting is too severe and the clot breaks free, the traveling clot is now known as an embolus.
Listen to conversations about Thromboembolism:
Clots in the veins of the legs or pelvis can migrate to the lungs. High risk times for anyone to get these pulmonary emboli exist when there have been prior clots, cancer, prior surgeries or hospitalization in general.
