To determine whether cord insertion can be consistently visualized and whether velamentous cord insertion and vasa previa can be consistently identified with color Doppler imaging during routine sonography in the mid‐trimester. 
Prenatal detection of velamentous insertion of the umbilical cord: a prospective color Doppler ultrasound study
TLDR
The aim of this study was to determine the feasibility of identifying velamentous insertion of the umbilical cord during routine obstetric ultrasound.
Early Suspicion of Vasa Previa with Velamentous Umbilical Cord Insertion and Low Lying Placenta and its Management
TLDR
The need for early suspicion of vasa previa in presence of persistent high risk features on repeated ultrasounds, importance of patient preparation with antenatal steroids as well as comprehensive education of patient regarding the warning signs and symptoms is demonstrated.
Velamentous insertion of the umbilical cord: intrapartum diagnosis
A report of velamentous insertion of the umbilical cord diagnosed during a normal twin delivery, a rare event with higher incidence in multiple pregnancies. Because it is generally asymptomatic, when
Prenatal Diagnosis of Velamentous Cord Insertion and Vasa Praevia using Ultrasound and Magnetic Resonance Imaging - A Case Report
TLDR
Prenatal diagnosis and early delivery by Caesarean section at 36 weeks improve fetal outcome and prenatal mortality is between 30%-100% from rupture of vessels and fetal exsanguination.
Velamentous cord insertion into the lower third of the uterus is associated with intrapartum fetal heart rate abnormalities
To evaluate the accuracy of sonographic identification of the site of umbilical cord insertion (CI) at 18–20 weeks of gestation, to compare the sensitivities for detection of a velamentous cord
Prenatal sonographic diagnosis of vasa previa: ultrasound findings and obstetric outcome in ten cases
TLDR
To assess the specificity of sonographic diagnosis of vasa previa and pregnancy outcome in sonographically diagnosed cases, a large number of cases with known pregnancies are studied.

TLDR
The objective was to assess the accuracy of ultrasound in the prenatal diagnosis of vasa previa, an obstetric complication in which the fetal blood vessels lie outside the chorionic plate in close proximity to the internal cervical os.
Prenatal Diagnosis of a Velamentous Cord Insertion Associated With a Vasa Previa
TLDR
A vasa previa is associated with very high fetal mortality rates and is often not detected until catastrophic events occur, and it is possible to diagnose both these conditions prenatally in order to provide clinical information pertinent to subsequent fetal outcome.
Umbilical Cord Insertion to the Lower Uterine Segment Is a Risk Factor for Vasa Previa
TLDR
Three cases of vasa previa diagnosed prenatally, with umbilical cord inserted to the lower segment of the uterus, are presented and it should be considered that umbilICAL cord insertion to theLower uterine segment is a high risk for vasaprevia.
