Is velamentous cord insertion considered high risk?
Abnormal cord insertions are associated with increased rates of abnormal FHR tracings and Cesarean deliveries. In particular, a VCI should be deemed a high-risk pregnancy and a warning sign of a possible vasa previa.
How do you know if a Velamentous cord is inserted?
How is velamentous cord insertion diagnosed? Your practitioner would likely be able to diagnose velamentous cord insertion based on ultrasound images of the placenta and umbilical cord — usually during the second trimester (although in some cases it can be detected in first trimester scans).
Where should the umbilical cord be positioned in the placenta?
Normally, the umbilical cord runs from the baby’s future bellybutton to the center of the placenta. If the insert site is slightly off the center, there’s no danger. But when the cord attaches near the edge or off the placenta entirely, as in around 10% of cases, there is danger to the baby.
Can velamentous cord insertion cause preeclampsia?
In pregnancies with anomalous cord insertion [velamentous (VCI) or marginal (MCI)] the risks of preeclampsia, abruption of the placenta, placenta previa, fetal growth restriction, preterm birth and fetal death are increased, as well as the risk of maternal complications in the third stage of labor 3, 4.
What is velamentous cord insertion in pregnancy?
Velamentous Cord Insertion Pregnancy Complications. A velamentous cord insertion is a pregnancy complication in which the umbilical cord is abnormally inserted into the placenta. In a typical pregnancy, a baby’s blood vessels travel from the center of the placenta into the baby via their umbilical.
What is the difference between normal gestational sac and velamentous insertion?
In a normal gestational sac, the umbilical cord is inserted into the middle of the placenta and entirely enclosed in the amniotic sac. In a velamentous insertion, the cord inserts itself into the amniotic membrane rather than in the placenta. The baby’s blood vessels then stretch along the membrane between the insertion point and the placenta.
What is a velamentous implantation?
In a velamentous insertion, the umbilical cord inserts itself into the amniotic membrane rather than in the placenta. The baby’s blood vessels stretch along the membrane between the insertion point and the placenta. As such, the vessels are unprotected because the substance that typically surrounds them, Wharton’s jelly, is missing. 2
What is the prevalence of velamentous cord insertion?
The prevalence may be slightly higher in stillbirths, particularly from multifetal pregnancies. In a velamentous cord insertion, the umbilical cord inserts into the fetal (chorio-amniotic) membranes outside the placental margin and then travels within the membranes to the placenta (between the amnion and the chorion).
