Detailed Description:

It has been shown that low dose acetylsalicylic acid (ASA) in pregnancy reduces adverse outcome of pregnancy in women that have high risk of developing preeclampsia (PE). It is a challenge for the clinician to identify the high risk women. Doppler blood flow measurements in uterine arteries in second trimester have been shown useful to predict the development of the disease but prophylactic treatment with ASA from this point in pregnancy has not been proven effective. Fetal Medical Foundation has developed an algorithm that calculates individual risks for PE/ PIH based on Doppler blood flow measurements and anamnestic information.
