Identifying patients at risk for preeclampsia would allow an increase in perinatal surveillance and possibly decrease the inherent maternal and fetal morbidity and mortality associated with severe preeclampsia and eclampsia. First and second trimester uterine artery Doppler velocimetry is a sensitive screening tool for the detection of preeclampsia and intrauterine growth retardation (IUGR) requiring delivery before 34 weeks. The performance of uterine artery Doppler velocimetry as a screening test depends on the prevalence of the adverse outcome in the studied population and whether the adverse outcomes are assessed individually or collectively as a group. Future research in this area should focus on identification of additional markers that may be incorporated into a prediction model for early identification of patients at risk for adverse outcomes.

    ABSTRACT: The placental dysfunction, which seems to be caused by a defect of trophoblastic invasion and impaired uterine vascular remodeling since the first trimester, is responsible in a non-exclusive way for the chronic placental hypoxia, resulting secondarily in the intra-uterine growth restriction (IUGR) and/or pre-eclampsia (PE). The quality of utero-placental vasculature is essential for a proper fetal development and a successful progress of pregnancy. However, the in vivo assessment of placental vascularization with non-invasive methods is complicated by the small size of placental terminal vessel and its complex architecture. Moreover, imaging with contrast agent is not recommended to pregnant women. Until recently, the fetal and maternal vascularization could only be evaluated through pulse Doppler of uterine arteries during pregnancy, which has little clinical value for utero-placental vascularization defects assessment. Recently, a non-invasive study, without use of contrast agent for vasculature evaluation of an organ of interest has become possible by the development of 3D Doppler angiography technique. The objective of this review was to make an inventory of its current and future applications for utero-placental vasculature quantification. The main findings of the literature on the assessment of utero-placental vascularization in physiological situation and major placental vascular dysfunction pathologies such as PE and IUGR were widely discussed.

    ABSTRACT: Preeclampsia is one of the leading causes of maternal and fetal morbidity and mortality. New molecular insights offer new possibilities of early diagnosis of elevated maternal risk. Maternal risk factors, biophysical parameters like Doppler examination of the uterine arteries and biochemical parameters allow early risk calculation. Preventive and effective therapeutic agents like acetylsalicylacid can be started in the early second trimester. This article reviews the diagnostic possibilities of early risk calculation to detect women having high risk for preeclampsia and the potential benefits for them, the offspring and health care systems. We provide risk calculation for preeclampsia as an important and sensible part of first trimester screening.

    ABSTRACT: Hypertension, proteinuria and biochemical changes caused by pre-eclampsia may persist for several weeks and even months postpartum. Hypertension and pre-eclampsia may even develop for the first time postpartum. Care in the six weeks postpartum should include management of hypertension and screening for secondary causes of hypertension including renal disease if abnormalities persist beyond six weeks. Optimal postpartum monitoring for patients with preeclampsia has not been determined, and care needs to be individualized. The postpartum period also provides a window of opportunity for planning for the next pregnancy in addition to discussing long term implications of pre-eclampsia. Increased risk for the development of premature cardiovascular disease is the most significant long term implication of pre-eclampsia. Pre-eclampsia and cardiovascular disease share a common disease pathophysiology. Women who develop pre-eclampsia have pre-existing metabolic abnormalities or may develop them later in life. Women with early onset pre-eclampsia are at the highest risk of ischemic heart disease. Women with a history of pre-eclampsia should adopt a heart healthy lifestyle and should be screened and treated for traditional cardiovascular risk factors according to locally accepted guidelines.
