What causes Velamentous insertion of the umbilical cord?
The exact cause of velamentous cord insertion is unknown, although risk factors include nulliparity, the use of assisted reproductive technology, maternal obesity, and pregnancy with other placental anomalies. Velamentous cord insertion is often diagnosed using an abdominal ultrasound.
How rare is velamentous cord insertion?
Velamentous insertion occurs in approximately 1% of all pregnancies. Velamentous cord insertion is more common among multi-fetal pregnancies, and has been estimated to occur in up to 10% of twin pregnancies, with increasing incidence with increasing number of fetuses in a multifetal gestation.
Does velamentous cord insertion require C section?
In the absence of vasa previa or placenta previa, it’s unlikely you would need a C-section based on a diagnosis of velamentous cord insertion alone. During labor you’ll likely have to be continuously monitored with a fetal heart monitor to make sure there are no complications from the abnormal cord placement.
What does Velamentous mean?
Velamentous insertion of umbilical cord: An abnormal condition in which the umbilical cord does not insert into the placental mass but, instead, traverses the fetal membranes before it inserts into the umbilical cord.
Can you have a vaginal delivery with Velamentous cord insertion?
A pregnant woman with umbilical prolapse, VCI, and a fetal vertex presentation can successfully deliver a baby through the vagina. Factors contributing to the success of the reported vaginal delivery might have been a small fetus, multipara status, and immediate management.
Can you deliver vaginally with Velamentous cord?
What do you do if you have Velamentous cord insertion?
How will I be treated for velamentous cord insertion? If you have velamentous cord insertion, your caregiver will monitor your baby and the placenta carefully with ultrasounds. Some practitioners also recommend regular (usually weekly) nonstress testing. During labor, your baby will receive continuous fetal monitoring.
What is the difference between marginal cord insertion and Velamentous?
A marginal cord insertion is where this distance is reduced to a minimum, but the insertion site is supported by very little placental tissue. Velamentous insertion of the umbilical cord has been associated with an increased risk of adverse perinatal outcomes [1]–[3].
What is velamentous cord insertion and how is it treated?
What Is Velamentous Cord Insertion? A velamentous cord insertion is a pregnancy complication in which the umbilical cord is abnormally inserted into the placenta. In a normal gestational sac, the umbilical cord is inserted into the middle of the placenta (central insertion) and entirely enclosed in the amniotic sac.
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.
What happens if the umbilical cord does not attach in proper location?
Rarely, the umbilical cord does not attach, or “insert,” in the proper location. There are two types of cord insertions that raise concerns. The first is marginal cord insertion. The second is velamentous cord insertion which is associated with vasa previa, a potentially dangerous combination that can cause complications.
Does every pregnancy with a velamentous cord insertion result in vasa previa?
Not every pregnancy with a velamentous cord insertion results in vasa previa, only those in which the blood vessels are near the cervix. When a velamentous cord insertion is discovered, the obstetrician will monitor the pregnancy closely for the presence of vasa previa.
