ABSTRACT
OBJECTIVE: To find whether mild forms of placenta creta (MPC) are more common in placentas delivered by cesarean section for non-anatomical indications than in placentas from vaginal deliveries.
METHODS: This is a retrospective clinical study. MPC was diagnosed histologically by the presence of myometrial fibers in the decidua basalis or parietalis or in direct contact with the Rohr fibrinoid or chorionic villi. After excluding 111 cases at high risk for anatomical PC, placentas from 830 consecutive cesarean deliveries (Group 1) were retrospectively statistically compared to 907 placentas from vaginal deliveries (Group 2).
RESULTS: Statistically significant differences were found in 6 independent clinical and 7 placental phenotypes: More frequent preeclampsia, abnormal fetal heart rate tracing and umbilical artery dopplers, hypercoiled umbilical cord, diffuse post uterine pattern of chronic hypoxic placental injury, and clusters of avascular or mineralized chorionic villi were found in Group 1, while preterm delivery, induction of labor and histological patterns related to stillbirth were observed in Group 2.
CONCLUSION: MPC diagnosed in placentas from cesarean sections performed for non-anatomical indications is not statistically significantly more common than in those after vaginal delivery. Therefore, MPC may feature similar diagnostic correlations and portend similar prognosis for future pregnancies.
