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.

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...
