Z37.3

Clinical Causes: Genetic abnormalities affecting fetal development Placental insufficiency leading to unequal growth Maternal health conditions like preeclampsia or infections Multiple pregnancies increasing the risk of complications Premature rupture of membranes or other preterm labor factors

Key Symptoms: Unequal growth rates observed in twins during pregnancy Signs of distress or compromised health in one fetus Labor complications arising during delivery Detection of stillbirths during routine ultrasounds or examinations Potential complications arising from uneven placental sharing

Diagnosis Path: Diagnosis of a twin where one is liveborn and the other is stillborn generally involves detailed obstetric assessments, including ultrasound imaging during pregnancy. Confirming the stillbirth is done through physical examinations and, if needed, autopsy to understand the cause. The distinction is made when only one twin is born alive, with the other remaining in the uterus or delivered stillborn. Medical records and fetal monitoring data support accurate classification.

Treatment Protocols: Management involves addressing the health needs of the liveborn twin, providing appropriate neonatal care, and offering emotional and psychological support to the family. The approach depends on the gestational age and health status of the liveborn twin, often including neonatal intensive care if necessary. Postpartum care for the mother might include counseling and screening to understand the causes and implications. Additionally, future pregnancies may require specialized monitoring and assessments.
