Placental pathological findings in the a control and b FGR groups. Placentas were fixed with formalin, stained with hematoxylin-eosin (HE), and then examined under the microscope. a Only scattered calcification and intervillous fibrin deposition (arrows) could be found in normal pregnant women. b Extensive infarcts (triangles) and reduced villus vessels were found in pregnancies complicated by FGR.
