It can result in long-term complications that include postthrombotic syndrome (PTS) adding to its morbidity.

EVs can be released by every cell type and they can be classified into three major groups according to their biogenesis, dimension, density, and predominant protein markers: exosomes, microvesicles, and apoptotic bodies. THE pathogenesis of thrombosis in man is still to a considerable extent a mystery despite the considerable advances in knowledge of the subject in recent years. The investigation of a heart valve patient with suspected hypercoagulability. Chronic myeloproliferative neoplasms (MPN) are characterized by clonal expansion of an abnormal hematopoietic stem/progenitor cell and include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). 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. Thus, both platelets and fibrin may accumulate over ruptured and eroded plaques. Blood clotting where it shouldn't or when you don't want it to.

Venous thrombosis. 2.Primary Pulmonary Tuberculosis – Since the most immediate location of pathogenesis of the organism is in the lungs, primary activation of disease in the pulmonary cavity is considered.It is usually asymptomatic and only identified through significant diagnostic examinations. In the pathogenesis of arterial thrombosis, platelet aggregation is responsible for the initial flow obstruction but fibrin formation is necessary for the subsequent stabilization of the platelet-rich thrombosis. The changes in platelets, coagulation, fibrinolytic systems leading to atherosclerosis and thrombi are reviewed.

The Pathogenesis of Thrombosis. The most devastating complication of this disease occurs when a platelet-rich thrombus abruptly occludes arterial blood flow, resulting in acute MI, stroke, or sudden cardiac death. Thrombosis markers and blood hypercoagulability markers, such as PAP, TM, and tPAIC, can be used as auxiliary indicators. Risk factors for chronic venous disease: the San Diego Population Study.
