Uteroplacental Circulation in Normal Pregnancy vs Preeclampsia Pregnancy

The document “Uteroplacental Circulation in Normal Pregnancy vs Preeclampsia Pregnancy” is a research-based study comparing normal and preeclamptic pregnancies. It explains that in normal pregnancy, spiral arteries are remodeled by trophoblasts into wide, low-resistance vessels ensuring proper blood flow to the placenta. In preeclampsia, this remodeling is defective, leading to reduced uteroplacental perfusion, placental ischemia, and release of antiangiogenic and inflammatory factors. These cause endothelial dysfunction, hypertension, and proteinuria. The study, involving 100 pregnant women, showed higher blood pressure, proteinuria, increased sFlt-1, decreased PlGF, and abnormal Doppler indices in preeclampsia. Placental examination revealed ischemic and degenerative changes. The paper concludes that early detection through angiogenic biomarkers and Doppler studies is crucial for preventing complications and improving maternal–fetal outcomes.
