Two cases of patients who delivered at our hospital were analyzed, both of whom exhibited sudden changes in fetal heart rate during the prenatal period and subsequently underwent emergency cesarean sections. Intraoperatively, both cases revealed a succenturiate placenta with ruptured umbilical vessels and bleeding.Results: Both cases resulted in adverse pregnancy outcomes due to succenturiate placenta and bleeding from ruptured umbilical vessels, with pathological examination of the placenta confirming the clinical diagnosis.Conclusion: Enhancing the detection rate of prenatal ultrasound for placental membranacea and umbilical cord vessel abnormalities, coupled with timely intervention, is crucial for reducing perinatal mortality.Keywords: umbilical vessel abnormalities, succenturiate placenta, pregnancy outcomes
