OBJECTIVE: This study aimed to clarify the maternal and neonatal outcomes based on the presence or absence of a Couvelaire uterus with placental abruption.
METHODS: This single-center retrospective study was conducted at a tertiary perinatal center in Japan, including patients diagnosed with acute placental abruption who delivered live births via cesarean section between 2016 and 2023. Patients were divided into two groups based on the presence or absence of a Couvelaire uterus during surgery: the Couvelaire and normal uterus groups. Maternal and neonatal outcomes were assessed.
RESULTS: This study included 76 patients: 24 in the Couvelaire group and 52 in the normal uterus group. No patients underwent hysterectomies. The Couvelaire group had significantly higher intraoperative blood loss (median 1152 vs 948 g, P = 0.010), blood transfusion rates (58% vs 31%, P = 0.022), fibrinogen administration rates (38% vs 13%, P = 0.038), intensive care unit/high care unit admission rates (29% vs 7.7%, P = 0.013), and disseminated intravascular coagulation complication rates (25% vs 7.7%, P = 0.038). There were no differences in birth weight, gestational age (median 2387 vs 2065 g, P = 0.082), Apgar score <4 at 5 min (4.2% vs 3.9%, P = 0.95), umbilical artery blood pH <7.1 (25% vs 22%, P = 0.82), and neonatal death (4.2% vs 1.9%, P = 0.57).
CONCLUSION: A Couvelaire uterus indicated adverse maternal outcomes but not neonatal ones. Its presence necessitates preparation for blood transfusions and/or intensive patient follow-up.
