Objective: The incidence of placental thrombotic lesions in early onset preeclampsia (PE) and/or intrauterine growth restriction (IUGR) were compared between women with and without thrombophilia or hyperhomocysteinemia.
Study design: Matched case-control study. 183 women with a history of early onset PE and/or IUGR were tested for thrombophilia and hyperhomocysteinemia. From the 66 women with a thrombophilic factor the placental histological slides were available in 47 women. These were matched for maternal condition (PE and/or IUGR), gestational age at delivery, parity and maternal age, to 47 women with no thrombophilic factor. All slides were revised for lymphohistiocytic villitis, fetal thrombosis and fibrin depositions.
Results: There were no significant differences between the placentas of the matched groups with and without a thrombophilic factor.
Conclusion: Placental thrombotic and inflammatory lesions associated with early onset PE and/or IUGR do not occur more often in women with compared to women without thrombophilia or hyperhomocysteinemia.
