Velamentous 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. When the membranes are ruptu...
متن کاملVelamentous 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...

A velamentous insertion of the umbilical cord is characterized by the atypical aspect of the placental end of the cord, consisting in divergent umbilical vessels surrounded by fetal membranes and with no Wharton’s jelly present, resulting a cord that is inserted rather into membranes than the placental disk. By the divergence of the umbilical vessels as they travers the amnion and the chorion b...
متن کاملVasa previa: prenatal diagnosis, natural evolution, and clinical outcome.
OBJECTIVE To describe the prenatal ultrasonographic diagnosis, natural evolution, and clinical outcomes of vasa previa in a large population at a single institution. METHODS We attempted to view the internal cervical os of 93,874 women with second- and third-trimester pregnancies during an 8-year period. Echogenic parallel or circular lines near the cervix, seen by gray-scale ultrasonography,...
متن کاملVelamentous Cord Insertion in a Singleton Pregnancy: An Obscure Cause of Emergency Cesarean—A Case Report
Approximately 2% 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 of emergency cesarean sections in low-risk women. Velamentous cord insertion is an abnorm...
