血栓性血小板减少性紫癜(TTP)较少见,其特征为:消耗性血小板减少、溶血性贫血、肾脏损害、神经系统损害及发热等。用新鲜冰冻血浆(FFP)治疗已使其死亡率从80%降低到20%,但这一疗法并非经常成功,当肾功能不全时较难掌握,且有传播病毒感染的风险。 Thrombotic thrombocytopenic purpura (TTP) is rare, characterized by: wasting thrombocytopenia, hemolytic anemia, renal damage, nervous system damage and fever. Treatment with fresh frozen plasma (FFP) has reduced its mortality from 80% to 20%, but this regimen is not always successful and is more difficult to grasp when renal insufficiency is present and there is a risk of spreading viral infections.
