Objective. The purpose of this study was to determine the feasibility of prenatal sonography for detecting velamentous insertion of the umbilical cord in singleton pregnancies at the 11‐ to 14‐week scan. Methods. The placental umbilical cord insertion site was prospectively examined at the time of the routine first‐trimester scan between 11 and 14 weeks as part of ongoing first‐trimester sonographic screening for chromosomal abnormalities. Results. Over a 1‐year period, 533 consecutive…

TLDR
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.
Antenatal Detection of Abnormal Placental Cord Insertion across Different Trimesters: A Prospective Cohort Study.
TLDR
Abnormal PCI can be detected antenatally with optimal agreement with postnatal classification in T2, however, the incidence is overestimated at early scans with low PPVs.
Obstetric Outcomes in Singleton Pregnancies with Abnormal Placental Cord Insertions.
TLDR
The results suggest that serial fetal growth assessments in this population may be warranted, and if an abnormal PCI is identified, the provider should consider serial growth ultrasounds.
Performance of ultrasound for the visualization of the placental cord insertion.
TLDR
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.
The role of ultrasound examination in the first trimester and at 16 weeks' gestation to predict fetal complications in monochorionic diamniotic twin pregnancies.
Velamentous cord insertion as a risk factor for obstetric outcome: a retrospective case–control study
TLDR
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.
Umbilical cord insertion site in early gestation and development of placenta
TLDR
The process of placental development and the placental location are affected by CI location at early gestation, and suggests that this process might be affected by poor blood supply from the low uterine segment when CI site is close to the internal cervical Os.
First trimester assessment of ductus venosus in screening for fetal chromosomal and cardiac defects
TLDR
It is suggested that flow through the ductus venosus can be assessed routinely at 11-13 weeks of gestation and that abnormal flow at this scan can help identify fetal chromosomal and structural defects as well as adverse pregnancy outcome.
Velamentous cord insertion: a rare cause of emergency caesarean section
TLDR
The case of a 28-year-old primigravida at 40 weeks gestation, who presented in active phase of labour, highlighted the importance of antenatal diagnosis of VCI and thus preventing catastrophic outcome.
Velamentous cord insertion: results from a rapid review of incidence, risk factors, adverse outcomes and screening
TLDR
In studies on limited numbers of cases, screening for VCI using TAS had good overall accuracy, driven by high specificity, and modelling studies may indicate the feasibility and value of studying the epidemiology of VCI and the potential impact of detecting VCI as part of a population screening programme for VP.

Clinical significance and sonographic diagnosis of velamentous umbilical cord insertion.
TLDR
Pregnancy outcomes in VCI patients with 77 singleton gestations were compared with a control group of 15,865 patients and, in contrast to the existing literature, multiparity and prior cesarean section deliveries were not increased in pregnancies with VCI.

Using fetal nuchal translucency to screen for major congenital cardiac defects at 10-14 weeks of gestation: population based cohort study
TLDR
Measurement of fetal nuchal translucency thickness—traditionally used to identify fetuses at high risk of aneuploidy—at 10-14 weeks of gestation can identify a large proportion of fetuses with major defects of the heart and great arteries.

TLDR
A study of 1000 cases has failed to demonstrate any association between marginal and velamentous insertion of the cord and high incidence of abortion, low birth weight, premature delivery, fetal malformation, fetal hypoxia and intrauterine fetal death.
