To evaluate perinatal outcomes in singleton and twin pregnancies with pathologically confirmed velamentous cord insertion without vasa previa. 
Impact of Marginal and Velamentous Cord Insertion on Uterine Artery Doppler Indices, Fetal Growth, and Preeclampsia
Abnormal cord insertion is more common in ART pregnancies and is significantly correlated with IUD, while MCI/VCI are associated with higher mean UtA PI and lower BW centile, but not with increased risk of PE.
Second‐Trimester Ultrasound‐Measured Umbilical Cord Insertion–to–Placental Edge Distance: Determining an Outcome‐Based Threshold for Identifying Marginal Cord Insertions
We sought to study potential diagnostic criteria for marginal placental cord insertions as determined by associations with obstetric outcomes.

The case demonstrated an unusual variation of vasa previa, in which a single fetal vessel separated from the membranous insertion located near the fundal placenta and traversed posteriorly through the chorionic membrane to within 0.83 cm of the internal os.
Placental Implantation Disorders.
Sonographic Diagnosis of Velamentous and Marginal Placental Cord Insertion
The purpose of this pictorial review is to illustrate examples of velamentous and marginal placental cord insertion with an emphasis on how to differentiate their morphology using color Doppler US.

The importance of characterizing the placental cord insertion is summarized and specific revisions to existing imaging guidelines and practices are recommended.
Current Perspectives of Prenatal Sonography of Umbilical Cord Morphology
This commentary will address current perspectives of prenatal sonography of the umbilical cord, including structural anomalies and the potential impact of future imaging technologies.
Performance of ultrasound for the visualization of the placental cord insertion.
Although the visualization of the PCI was lower with advancing gestational age, it remained high even into the late third trimester, and Ultrasound with color Doppler is also an excellent screening test for the diagnosis of VCI.

Placental Abnormalities
The goal of this chapter is to delineate the real-world implications of placental abnormalities and provide the reader with a basis for understanding the other chapters that will delve into microbiology, genomics, immunohistochemistry, and biochemistry of the placenta.

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
Velamentous or marginal cord insertion and the risk of spontaneous preterm birth, prelabor rupture of the membranes, and anomalous cord length, a population‐based study
The aim was to study whether anomalous cord insertion is associated with prelabor rupture of membranes (PROM), preterm PROM, long or short umbilical cord, and time trend of spontaneous preterm birth (SPTB) and anomalous Cord insertion.
Third stage of labor risks in velamentous and marginal cord insertion: a population‐based study
To assess whether anomalous cord insertion is associated with risk of complications in the third stage of labor, a large number of women with high-risk pregnancies have had an abnormal cord insertion during pregnancy.
Prenatal detection of velamentous insertion of the umbilical cord: a prospective color Doppler ultrasound study
The aim of this study was to determine the feasibility of identifying velamentous insertion of the umbilical cord during routine obstetric ultrasound.
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

VCI is associated with an increased risk of adverse perinatal outcomes such as intrauterine fetal demise, SGA, preterm delivery <37 weeks, need for manual removal of placenta and post-partum hemorrhage.
Velamentous cord insertion as a risk factor for obstetric outcome: a retrospective case–control study
The last pulsatility index value in the umbilical artery, before delivery, was significantly higher in pregnancies with VCI, which is of uncertain clinical value, and higher rates of (early) preterm delivery were found.
Prevalence, Risk Factors and Outcomes of Velamentous and Marginal Cord Insertions: A Population-Based Study of 634,741 Pregnancies
The two conditions shared risk factors; twin gestation and pregnancies conceived with the aid of assisted reproductive technology were the most important, while bleeding in pregnancy, advanced maternal age, maternal chronic disease, female foetus and previous pregnancy with anomalous cord insertion were other risk factors.
