OBJECTIVE: We aimed to examine the association of clinical risk factors and placental lesions, in gestations complicated with preeclampsia, with the need for antihypertensive treatment in the early postpartum period.
METHODS: The computerized files and placental reports of all singleton deliveries at 24.0-42.0 weeks complicated by preeclampsia were reviewed between January 2013 and October 2020. Obstetric characteristics and placental lesions were compared between patients who required antihypertensive treatment in the early postpartum period and those who did not (control group). Placentas were classified into maternal and fetal malperfusion lesions and inflammatory responses.
RESULTS: As compared to controls (n = 200), the anti-hypertensive treatment group (n = 95) was characterized by increased rates of preterm birth, preeclampsia with severe features, and cesarean delivery (p < 0.001 for all). More placental hematomas (p = 0.01) and placental maternal vascular lesions (p = 0.03) were observed in the antihypertensive treatment group as compared to controls. In adjusted logistic regression analysis, gestational age (OR 0.86, 95% CI 0.79-0.93, p = 0.001) and preeclampsia with severe features (OR 8.89, 95% CI 3.18-14.93 p < 0.001) were found to be independently associated with the need for postpartum antihypertensive treatment.
CONCLUSION: Placental vascular lesions are more common in preeclamptic patients who need postpartum antihypertensive treatment, yet only early onset of preeclampsia with severe features was found to be independently associated with antihypertensive treatment in the early postpartum period.
