由血栓引起的疾病叫血栓症。而通常在不会形成血栓的条件下形成血栓损害机体的状态叫做凝血亢进状态。血栓形成有许多因素参与,如家族性,血液粘度及血小板变化,血液动力学障碍、肥胖等。近年来发现血管内也存在着凝血机制的发展,而这种发展十分缓慢。正常人体有完整的凝血抗凝和纤维蛋白溶解系统。正常人的血管内即使有少量的活性凝血中间产物形成也能被单核巨噬细胞所清除或被血中抗凝物质中和。纤溶系统不断溶解小血管损伤产生的纤维蛋白,失去这种平衡促进血液凝固或产生大量的纤维蛋白,或者被溶解的过程受到阻碍均可产生凝血亢进。
Thrombosis caused by thrombosis disease. In general, the condition in which thrombus damages the body without forming a thrombus is called hypertrophic state. Thrombosis has many factors involved, such as familial, blood viscosity and platelet changes, hemodynamic disorders, obesity and so on. In recent years, blood vessels also found that the development of coagulation mechanisms, and this development is very slow. Normal human body has a complete coagulation anticoagulant and fibrinolytic system. Normal human blood vessels even if a small amount of active coagulation intermediates can also be formed by mononuclear macrophages or blood anticoagulant neutralization. Fibrinolysis systems continue to dissolve fibrin produced by small vessel damage, and loss of this balance promotes blood clotting or produces large amounts of fibrin, or clotting may occur when the process of dissolution is hindered.
