Clinical 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...
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...
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. When the membranes are ruptu...
متن کاملUmbilical Venous Doppler Velocimetry to Supplement Conventional Arterial Doppler to Assess Third Trimester Fetal Growth Restriction
HKJGOM 2009; 9 (1) 28 Introduction Fetuses born with significant growth restriction have an increased risk of adverse perinatal outcomes1. Moreover, increased perinatal morbidity and mortality was often associated with the presence of abnormal Doppler waveforms in the umbilical arteries (UAs), either in the form of absent or reversed end-diastolic flow2,3. In fetuses with abnormal umbilical art...
متن کاملVelamentous cord insertion - an important obstetrical risk factor
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...
