Figure 5.1

Scanning electron microscopy of placental villi from normal, preeclampsia and IUGR pregnancies. A: from a normal placenta: long slender, slightly curved mature intermediate villi with moderate number of grape-like terminal villi are the dominant features in the normal placenta.; B: from a preeclamptic placenta (uteroplacental hypoxia) showing the multiply branched, shot capillary loops with shot, knob-like indented villous surfaces; and C: from an IUGR placenta (postplacental hypoxia) showing long and poorly branched bundles of terminal villi. (The EM photos are adapted From Pathology of the human placenta, 5th Edition. Chapter 15: classification of villous maldevelopment. Edited by: Benirschke et al. A: from Figure 15.11A; B: from Figure 15.16 A; and C: from Figure 15.17 A). Reproduced from Pathology of the Human Placenta 5e, Benirschke et al. with permission of Springer.
