Case Report : Clinical Management Of a Twin Pregnancy Complicated With An Acardiac Fetus Detected In The Prenatal Period

<ns3:p>Background The acardiac fetus is a rare malformation specific to multiple monozygotic pregnancies. Two main theories have been proposed regarding the etiology of this malformation: the vascular theory, and the second supposes a defect in the embryogenesis of the heart. Diagnosis is typically suspected and confirmed based on ultrasound findings. Case presentation We present the case of a 36-year-old woman, G3P4, with a bi-scarred uterus. The last pregnancy was a monochorionic monoamniotic twin pregnancy complicated by an acardiac fetus suspected in the first trimester and confirmed by ultrasound at 23 weeks of gestation. She gave birth by an emergency cesarean section at 34 weeks + 4 days to two babies: a normal female baby and an acardiac fetus. Conclusion Acardiac twin pregnancies present challenges and require careful management to optimize outcomes for both the acardiac and the healthy twins. Understanding the mechanisms underlying this condition is crucial to provide effective prenatal care and support.</ns3:p>
