妊娠相关性血小板减少症指的是妊娠前无血小板减少的病史,妊娠期首次发现血小板计数低于正常值(<100×109/L)。抗血小板抗体阴性,肝肾功能及凝血功能正常。其特点为只发生于妊娠期间,多发现于妊娠中晚期,一般血小板减少的程度轻,无明显出血表现及病史,产后血小板多在2~12周恢复正常,胎儿及新生儿多不发生血小板减少和出血。其诊断为排除性诊断,需与其他引起血小板减少的疾病作鉴别,其中与妊娠合并特发性血小板减少性紫癜的鉴别尤为重要。本文就此病的诊断与鉴别诊断、临床处理作一阐述。
Pregnancy-associated thrombocytopenia refers to a history of thrombocytopenia prior to pregnancy with a platelet count lower than normal (<100 × 109 / L) found for the first time during pregnancy. Anti-platelet antibody negative, liver and kidney function and coagulation function is normal. It is characterized by only during pregnancy, and more found in the second trimester of pregnancy, the general degree of thrombocytopenia was mild, no significant bleeding and history, postpartum platelets returned to normal in 2 to 12 weeks, most of the fetus and newborns do not occur thrombocytopenia And bleeding. The diagnosis of exclusion diagnosis, need to be identified with other diseases that cause thrombocytopenia, of which pregnancy and idiopathic thrombocytopenic purpura identification is particularly important. This article on the diagnosis and differential diagnosis of the disease, an elaboration of clinical treatment.
