Velementous cord

Velamentous cord insertion is an abnormal condition during pregnancy. Normally , the umbilical cord inserts into the middle of the placenta as it develops. In velamentous cord insertion, the umbilical cord inserts into the fetal membranes ( choriamniotic membranes), then travels within the membranes to the placenta . VCI is in which umbilical cord is inserted into chorioamniotic membranes.

Normally, the blood vessels of the baby run from the middle of the placenta via the umbilical cord to the baby.

The umbilical cord inserts on the placental mass in .

Epidemiology The estimated incidence is ~ in singleton and 9- in twin pregnancies, respectively 11.

Author information: (1)Department of Obstetrics and Gynecology, Saga Prefectual Hospital Kouseikan, Japan. The prevalence of abnormal cord insertion was 7. A velamentous umbilical cord is characterized by membranous umbilical vessels at the placental insertion site that are prone to compression and rupture, especially when they are located in the membranes covering the cervical os ( vasa praevia). The velamentous insertion of the umbilical cord , with a . Umbilical cord inserting into the membranes of the placenta rather than onto the placental mass (1-11). The vessels are unsupported by either the umbilical cord or placental tissue.

Seen above and below are examples of velamentous insertion of the umbilical cord in which the major umbilical vessels separate in the fetal membranes before reaching the placental disk. Approximately of low-risk pregnant women still require an emergency Cesarean section after the onset of labor. Because it is likely that half of these cases are associated with placental and umbilical cord abnormalities, it is thought that prenatal detection of such abnormalities would reduce the number .
