Definition定义 Disseminated intravascular coagulation(DIC)is a clinicopathologic syndrome in which widespread intravascular coagulation is induced by procoagulants that are introduced or produced in the blood and overcome the natural anticoagulant mechanisms.Perturbation of the endothelium in the microcirculation along with stimulated inflammatory cells play a key role in its mechanism.广泛血管内凝血的临 床病理综合症,内皮损害和炎症细胞刺激是关键。 The clinical manifestations of intravascular coagulation include(1)multiorgan dysfunction caused by microthrombi, (2)bleeding caused by consumption of platelets,fibrinogen, factor V,and factor VIll,and (3)secondary fibrinolysis and platelets exhaustion..微血管内血栓、 凝血因子血小板消耗、 继发性纤溶活化和出血表现
Definition 定义 • Disseminated intravascular coagulation (DIC) is a clinicopathologic syndrome in which widespread intravascular coagulation is induced by procoagulants that are introduced or produced in the blood and overcome the natural anticoagulant mechanisms.

DIC的其它病因 3) malignant disease恶性肿瘤:白血病、淋 巴瘤、腺癌等。 4) intensive traumas严重的组织创伤、烧伤、 主动脉瘤撕裂 5)Other disease其它:原发性巨大血管瘤、心 脏附壁血栓、蛇毒或活化凝血因子(凝血 酶原复合物)大量进入机体、PNH溶血发作、 急进性肾炎、糖尿病酮症酸中毒、系统性 红斑狼疮、中暑等

病例一 何某,女,34岁 。 停经36+3周,发现血小板减少六月,三月前血 小板计数52×10儿,曾检查抗高尔基抗体阳性, 风湿免疫科诊断为结缔组织病,近10天发现血 小板计数下降为34×10/儿,泼尼松、丙球治疗 后,仍然出现血小板进行性下降至28×10儿, 凝血功能检测除发现PT缩短<10s没有发现其它 异常,此次妊娠单胎、头位,一直没有出血现 象。 问题:是否考虑DIC血小板消耗性低下?
