Abstract

Objective The aim was to compare placental volumes (PVs) and vascularization between normotensive pregnant women and women with hypertensive disorders using three-dimensional sonography. Background Hypertensive disorders in pregnancy are responsible for substantial maternal and fetal morbidity and mortality. Materials and methods This study was conducted at the Outpatient Clinic and Obstetric Departments of Shebin El Kom Teaching Hospital from February 2017 to January 2018. This study included 60 pregnant women, among which 20 were with normal blood pressure which served as the control group (group 1) and 20 were having chronic hypertension (group 2), and 20 with mild preeclampsia (group 3). Full history taking, physical examination, and laboratory investigation were done. Each patient from each group underwent three-dimensional ultrasound examination of the placenta for PV and placental vascular indices. Results There was significant statistical difference between three groups as regards PV to fetal weight ratio, with significant statistical differences between normotensive and chronic hypertensive groups (P = 0.016) and with significant statistical differences between normotensive and mild preeclamptic groups (P = 0.002). As regards placental vascular indices, there was high significant statistical differences between the three study groups (P = 0.001) as regards placental vascularization index with significant statistical differences between the three studies groups as regards placental vascular flow index (P = 0.03), But, there was no significant statistical difference between the tree groups as regards placental flow index (P = 143). Conclusion Pregnancies complicated by hypertensive disorders are associated with reduced placental vascularity but not with reduced PVs.
