Velamentous insertion of umbilical cord with vasa praevia: case series and literature review
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 reported incidence of 1% in singleton pregnancies and 15% in monochorionic twin gestations, has b...
متن کاملVelamentous insertion of the umbilical cord vessels with vasa praevia--a case report.
Among the abnormal cord insertion pathology, velamentous cord insertion associated with rupture of vasa praevia is the most severe condition related to the outcome of the newborn. In velamentous cord insertion, the fetal vessels run freely through the fetal membranes without protection from Wharton's jelly, umbilical vessels diverging as they traverse the membranes.

متن کاملClinical Significance of Pregnancies Complicated by Velamentous Umbilical Cord Insertion Associated With Other Umbilical Cord/Placental Abnormalities
BACKGROUND We examined the clinical significance of pregnancies complicated by velamentous cord insertion (VCI) associated with other umbilical cord/placental abnormalities. METHODS Data were collected from 168 deliveries complicated by VCI and from 16,797 unaffected controls. All placentae were screened identically by trained staff. In this study, we examined the presence of excessively long...
