Thromboembolism is a condition in which a blood clot breaks off from its original site and travels through the bloodstream (as an embolus) to obstruct a blood vessel, causing tissue ischemia and organ damage. Thromboembolism can affect both the venous and arterial systems, with different clinical manifestations and management strategies.
The treatments to prevent the formation of blood clots is balanced against the risk of bleeding. [5] One of the goals of blood clot prevention is to limit venous stasis as this is a significant risk factor for forming blood clots in the deep veins of the legs. [6] Venous stasis can occur during the long periods of not moving.
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
Treatment for DVT is warranted when the clots are either proximal, distal and symptomatic, or upper extremity and symptomatic. [2] Providing anticoagulation, or blood-thinning medicine, is the typical treatment after patients are checked to make sure they are not subject to bleeding. [2] [i] However, treatment varies depending upon the location ...
Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss ...
The blockages may also result from scar tissue that forms at the site where the clot has damaged the endothelial lining of the pulmonary arteries, causing permanent fibrous obstruction (blood flow blockage). [8] Most patients have a combination of microvascular (small vessel) and macrovascular (large vessel) obstruction.
