The Risk Factors for Placental Abruption in Preeclamptic Pregnancies: A Retrospective Case-Control Study.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatology

Background:

• Preeclampsia is a significant risk factor for placental abruption.
• Early identification of placental abruption in preeclamptic women is challenging due to unclear accompanying symptoms.

Purpose of the Study:

• To identify the clinical symptoms and disease phenotype associated with placental abruption in preeclamptic women.
• To determine risk factors for placental abruption in the preeclamptic population.

Main Methods:

• Retrospective analysis of obstetric data from 709 preeclamptic women (January 2016 - June 2023).
• Women were categorized into placental abruption and non-placental abruption groups.
• Logistic regression analysis was used to identify risk factors.

Main Results:

• Placental abruption group (39 cases) had younger maternal age, lower BMI, and higher HELLP syndrome incidence.
• Risk factors included elevated systolic blood pressure, blurred vision, positive urine protein, and lower platelet counts and maternal age.
• The placental abruption group experienced shorter gestational age, increased C-section rates, fetal growth restriction, and neonatal asphyxia.

Conclusions:

• Placental abruption in preeclampsia critically affects neonatal well-being.
• Close monitoring of systolic blood pressure, urine protein, platelet counts, and visual acuity is vital for early detection.
• Prompt identification can mitigate adverse neonatal outcomes.
