(724) Perinatal Outcomes in Patients with Pre-eclampsia with Severe Features and Placental Abruption

Thursday, February 12, 2026
10:30 AM - 12:00 PM  
Objective:
The objective of this study was to identify how maternal and neonatal outcomes differ amongst patients with pre-eclampsia with severe features (SPE) depending on the presence or absence of placental abruption.

Study Design:
This is a retrospective cohort study including patients diagnosed with SPE and placental abruption who delivered at a single institution between January 2019 and November 2024. Perinatal outcomes during delivery were compared between patients diagnosed with SPE who were also diagnosed with placental abruption to those with SPE alone. Patients diagnosed with SPE postpartum were excluded.

Results:
Of 5,056 deliveries complicated by SPE, 182 (4%) had both SPE and abruption. These patients were more likely to deliver via cesarean delivery (63% vs 42%, p< 0.001) and to experience a stillbirth (17% vs 1%, p< 0.001). Median estimated blood loss was increased (1250 (750-1500cc) vs 750 (500-1000cc), p< 0.001) and rate of transfusion (33% vs 14%, p< 0.001) higher in this cohort. If transfused, patients with SPE and abruption received fresh frozen plasma (FFP) and cryoprecipitate at higher rates (both p< 0.001). Neonates born to mothers with SPE and placental abruption had worse outcomes in all assessed neonatal outcomes including depressed Apgar scores, acidemia, NICU admission, and need for therapeutic hypothermia (all p< 0.05) (Table 2).

Conclusion:
Patients with SPE and placental abruption have worse maternal and neonatal outcomes when compared to SPE alone. Providers should remain alert to the association of SPE with abruption and the subsequent possible perinatal outcomes.
