Can you have Velamentous cord insertion without vasa previa?
When a velamentous insertion occurs away from the cervix (i.e. when there is no vasa previa), most pregnancies proceed normally with no complications. Occasionally, however, intrauterine growth restriction may occur.
Is vasa previa the same as Velamentous cord insertion?
Definition: Vasa previa is defined when unprotected umbilical vessels run through the amniotic membranes, and pass over the cervix. Two types: Type I: Velamentous cord insertion and fetal vessels that run freely within the amniotic membranes overlying the cervix or in close proximity of it (2cm from os).
How often does Velamentous cord insertion turn into vasa previa?
About 2% of velamentous insertions are associated with a vasa previa (14–16). Placenta membranacea (22) is also a risk factor. It is less clear why, but in-vitro fertilization increases the risk of vasa previa (17–20), (about 1:300 pregnancies) (21).
What is the difference between vasa previa and cord prolapse?
Vasa previa must be distinguished from funic presentation (prolapse with the umbilical cord between the presenting part and the internal cervical os), in which fetal blood vessels wrapped with Wharton jelly can be seen covering the cervix.
Should I be worried about velamentous cord insertion?
Velamentous and Marginal Cord Insertion Risks Typically, marginal cord insertion has little negative effect. However, there is a high risk of hemorrhage, or blood loss, for infants with velamentous cord insertion because the umbilical blood vessels are unprotected by umbilical tissue.
Should I worry about Velamentous cord?
A velamentous cord insertion can indirectly lead to brain damage because it may restrict fetal growth. 15 Babies who are small for gestational age are at risk for a condition called hyperbilirubinemia, which can lead to brain damage.
Can placenta previa become vasa previa?
Vasia previa can occur when the umbilical cord inserts itself into one of these membranes. Sometimes the placenta attaches itself to the lower part of the uterus, covering part or all of the cervix. This condition is known as placenta previa, or low-lying placenta. 7 This increases the risk of vasa previa.
What is Velamentous insertion?
A velamentous cord insertion is a rare 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.
Can you have placenta previa and vasa previa?
What is a Velamentous cord insertion?
Velamentous cord insertion is an abnormal cord insertion in which the umbilical vessels diverge as they traverse between the amnion and chorion before reaching the placenta. With a reported incidence of 1% in singleton pregnancies, it has been associated with several obstetric complications.
Can you have a healthy baby with velamentous cord insertion?
Happily, the chances that this pregnancy complication can hurt your baby are very low. That said, velamentous cord insertion can increase the risk of preterm birth, a small-for-gestational-age baby, low Apgar score, and the need for a stay in the neonatal intensive care unit (NICU) after birth.
