围产医学是70年代发展起来的一门新兴学科.分娩前后一定时期内孕妇的各种可以危害胎婴儿的疾病是其研究内容之一.妊娠合并特发性血小板减少性紫癜(ITP)属高危妊娠的范畴,近来对其研究有一些新进展,本文仅做简要的综述。病因I T P 也称为自身免疫性血小板减少性紫癜,是一种以抗血小板抗体形式为特征的综合征.这种主要产生于脾脏的 IgG 抗体直接作用于血小板表面抗原,导致血小板被巨噬细胞-网状内皮系统破坏,循环中血小板数量不同程度地减少,进而影响止血过程.诊断I T P 的诊断主要靠血板减少、骨髓中巨核细胞增多而没有其它血液学的异常和不存在血小板减少的继发原因、胶原血管性疾病和脾功能亢进等.值得注意的是,在应用依地酸做抗凝剂经自动细胞计数器进行血小板计数的情况下,由于血小板在试
Perinatal medicine is a new discipline developed in 1970s.It is one of the research contents of all kinds of maternal diseases that may endanger the fetus in infants before and after delivery.Pregnancy complicated idiopathic thrombocytopenic purpura (ITP) is a high risk Recent areas of pregnancy have some new developments in their research, and this article only briefly reviews. Etiology ITP, also known as autoimmune thrombocytopenic purpura, is a syndrome characterized by an anti-platelet antibody that is produced directly by the spleen’s IgG antibodies to platelet surface antigens, resulting in platelets being blocked by macrophages- Reticuloendothelial system is destroyed, the number of circulating platelets decreases to varying degrees, thereby affecting the process of hemostasis.The diagnosis of ITP mainly depends on the reduction of blood platelets, the increase of megakaryocytes in bone marrow without other hematological abnormalities and the absence of thrombocytopenia Causes, collagen vascular disease and hypersplenism etc .. It is noteworthy that, in the application of edetic acid anticoagulants by the automatic cell counter platelet count in the case of platelets in the test
