In the present study, no statistically significant
difference was shown in the placental villi volume
and intervillous spaces between PP and C groups.
As mentioned above, there is no precise data concerning
structural changes of placental villi in PP.
Mayhew et al. studied the placentas of preeclampsia
patients (PE) by stereological method and
found no significant difference between PE and
control groups in terms of placental villi volumes
(13). But the studies of Ducray et al. using an image
analysis method on PE patients’ placentas
indicated that there was an increase of placental
villi volume and also significant reduction of intervillous
space volume (15).
