Twin pregnancies represent approximately 3% of births and are associated with increased risks of complications such as preeclampsia, fetal growth restriction and preterm birth. All of these complications are commonly associated impaired placental function and low birth weight.
Most prophylactic measures tested over the years have failed to prevent these adverse outcomes in twin pregnancies. Since administration of low-dose of aspirin can improve placental function and all these adverse outcomes in high-risk pregnancies, mainly in women with prior adverse outcomes, we suggest that similar benefits could be seen in twins. We are expecting that the administration of low-dose of aspirin starting in the first-trimester in twin pregnancies could lead to an improvement of placental function, a reduction or these adverse perinatal outcomes and therefore to an improvement of birthweight.
