  • 简介:AbstractAspirin, one of the most widely applied medicines, not only possesses the effects on reducing fever, anti-vascular hyperplasia, and anti-inflammation, but also has the capacity of preventing platelet aggregation. So far, it is acceptable to adopt aspirin, especially low-dose aspirin (LDA), to prevent pregnancy-related complications, such as pregnancy complicated by antiphospholipid syndrome, systemic lupus erythematosus, or preeclampsia; unexplained recurrent spontaneous abortion; fetal growth restriction; and preterm birth. In this article, we reviewed the possible mechanism of action and applications of aspirin in these pregnancy-related complications.
