Abstract/OtherAbstract:
OBJECTIVE: To identify pathological placental differences between early-onset and late-onset preeclampsia, in relation to fetal growth restriction (FGR). METHODS: Placentas from patients with preeclampsia were analyzed for lesions of maternal vascular supply consistent with maternal underperfusion and lesions of fetal vascular supply consistent with fetal thrombo-occlusive disease. Findings were compared between patients who gave birth before 34 weeks (early-onset preeclampsia) and after 34 weeks (late-onset preeclampsia). RESULTS: Compared with the late-onset group (n = 93), the early-onset group (n = 37) had higher rates of FGR (62.2% vs 25.8%, P < 0.001) and lesions of maternal vascular supply (95% vs 60%, P < 0.001). Within the early-onset group, cases with FGR (n = 23) had more lesions of fetal vascular supply (47.8% vs 7%, P = 0.01), with similar high rates of lesions of maternal vascular supply (91% vs 100%) compared with those without FGR. Within the late-onset preeclampsia group, cases with FGR (n = 24) had higher rates of maternal vascular supply lesions (88% vs 51%, P = 0.003) than those without FGR, but similar rates of fetal vascular supply lesions (25% vs 16%, P = 0.32). CONCLUSION: The placental fetal vascular supply lesions in combination with maternal vascular lesions are more dominant in early-onset preeclampsia with FGR as compared with early-onset preeclampsia without FGR. © 2012 John Wiley & Sons, Ltd.
