A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.

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 ...
A pulmonary embolism (PE) occurs when a blood clot from a deep vein (a DVT) detaches from a vein , travels through the right side of the heart, and becomes lodged as an embolus in a pulmonary artery that supplies deoxygenated blood to the lungs for oxygenation. [28] Up to one-fourth of PE cases are thought to result in sudden death. [12]
This leads to an occlusion of the artery and thus ischemia. Unlike embolic causes of limb ischemia, thrombosis is progressive and develops over time. In hypercoagulable states, thrombosis can occur in areas without atherosclerosis, and usually presents in patients with malignancy, increased tendency for blood to clot, or low blood flow. [15]
Thrombolysis, also called fibrinolytic therapy, is the breakdown of blood clots formed in blood vessels, using medication. It is used in ST elevation myocardial infarction, stroke, and in cases of severe venous thromboembolism (massive pulmonary embolism or extensive deep vein thrombosis). [citation needed]
A subsequent systematic review of nineteen studies in 2006 showed that mortality is about 5.6% during hospitalisation and 9.4% in total, while of the survivors 88% make a total or near-total recovery. After several months, two thirds of the cases has resolution ("recanalisation") of the clot. The rate of recurrence was low (2.8%). [24]
In the 40-60% of people who go on to develop venous gangrene, there is a 20-50% risk of amputation and 20-40% mortality rate. [ 24 ] [ 25 ] Following PCD resolution patients are more likely to develop venous insufficiency and post-thrombotic syndrome [ 26 ]
