播散性血管内凝血(Disseminated intravascular Coagulation,简称DIC)是一个综合征。在某些致病因素的作用下,引起微循环内(主要是毛细血管和微静脉)广泛的纤维蛋白沉积和血小板凝聚,形成广泛的微血栓,并迅速消耗大量的血小板和凝血因子,造成凝血障碍,乃至出血。故又名“消耗性凝血病”(Consumption coagulopathy),“去纤维蛋白综合征”(Defibrination syndrome),或“血管内凝血合并纤维蛋白溶解综合征” Disseminated intravascular coagulation (DIC) is a syndrome. Under certain pathogenic factors, it causes extensive fibrin deposition and platelet aggregation within the microcirculation (mainly the capillaries and venules) to form extensive microthrombi and quickly consume large amounts of platelets and clotting factors, causing coagulation Obstacles, and even bleeding. It is also known as Consumption coagulopathy, Defibrination syndrome, or “Intravascular coagulation with fibrinolysis syndrome”
