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...
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 کاملPlacenta previa: distance to internal os and mode of delivery.
OBJECTIVE The purpose of this study was to relate the mode of delivery and outcomes in a cohort of cases of placenta previa that had the last transvaginal ultrasonographic scan <28 days before delivery. STUDY DESIGN Cases in which the placental edge overlapped the internal cervical (n = 42) underwent cesarean section delivery. Labor was allowed in those with placental edge to internal os dist...
متن کاملDo All Cases of Vasa Previa Need Cesarean Delivery? A case Report and Review of the Literatures
Vasa previa (VP) is defined as fetal vessels unsupported by either placenta or umbilical cord coursing within the membranes in close proximity to the internal cervical os [1]. The membranous fetal vessels can either lead from the placenta to a velamentous cord insertion (type 1) or connect the main bulk of the placenta to a succenturiate lobe (type 2) [2]. The localization of the membranous fet...
