Analysis of the placental vascularization. (A) The gross observation of the umbilical artery to the chorionic artery, and the thick stem chorionic villous artery which continues as the primary branch in the placenta. (B) The primary branching arteries continuously branch to form a tree like structure. (C,D) The HR-flow and waveforms from a PE pregnant woman at gestational age of 37W. (E,F) The HR-flow and waveforms from a gestational hypertension pregnant woman at gestational age of 33W. Double headed arrow: chorionic artery; White solid arrows: thick stem chorionic villous artery, and the primary branch within the placenta; Orange solid arrow: secondary branch; Orange humble arrow: third branch; White humble arrow: fourth branch; W: week; PE: pre-eclampsia; HR-Flow: high resolution flow.
