To evaluate the role of ultrasound in prenatal diagnosis of vasa praevia (VP) and to asses the risk of VP associated with different causal factors. 
Vasa Praevia: a descriptive review of existing literature and the evolving role of ultrasound in prenatal screening
TLDR
Prenatal detection of vasa praevia during the mid‐trimester morphology ultrasound scan and a lack of consensus about the appropriate management of pregnancies once it is detected are addressed.
Incidence of and risk indicators for vasa praevia: a systematic review
Vasa praevia (VP) is a rare phenomenon that is assumed to increase the risk of severe complications, including fetal death. Critical data on its incidence are lacking, so there is no rational basis
Perinatal outcome of pregnancies with prenatal diagnosis of vasa previa: systematic review and meta‐analysis
To derive accurate estimates of perinatal survival in pregnancies with and without a prenatal diagnosis of vasa previa based on a systematic review of the literature and meta‐analysis.
Vasa praevia: diagnosis and management
TLDR
Vasa praevia occurs when unprotected fetal vessels cross the cervix beneath the presenting part and rapid fetal haemorrhage can result.
A survey of opinion and practice regarding prenatal diagnosis of vasa previa among obstetricians from Australia and New Zealand
TLDR
To define current obstetric opinion and clinical practice regarding the prenatal diagnosis of vasa previa in Australia and New Zealand, it is suggested that women with a history of high-risk pregnancies should be referred to a specialist for treatment of this condition.
Prenatal diagnosis of vasa previa and the course of the cord vessels contribute to the safety of cesarean sections: A case report
TLDR
The color Doppler is a useful and easy‐to‐use device to confirm the presence of vasa previa and its course contributes to a safe delivery.

Systematic review of accuracy of ultrasound in the diagnosis of vasa previa

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.
Is neonatal risk from vasa previa preventable? The 20‐year experience from a single medical center
TLDR
Assessment of the prenatal detection of vasa previa and its subsequent impact on neonatal outcomes in two 10‐year periods (1988–1997 versus 1998–2007) found no change in neonatal morbidity and mortality.
Are we over‐diagnosing vasa praevia? The experience and lessons learned in a tertiary centre
TLDR
There is little data available on the false positive rates for the antenatal diagnosis of VP, but improving accuracy of the diagnosis can potentially improve outcomes and reduce unnecessary intervention.

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.
Diagnosis of vasa previa with ultrasonography.
An antepartum diagnosis of vasa previa was considered in a patient in whom ultrasound revealed pulsatile loops of cord overlying the cervical os. This diagnosis was confirmed at the time of cesarean

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.
Survival of twins after acute fetal hemorrhage from ruptured vasa previa.
TLDR
This is the first reported case in which both twins survived vasa previa complicated by ruptured membranes, and both neonates appear normal at the age of 6 months.
Association of vasa previa at delivery with a history of second-trimester placenta previa.
TLDR
There is a highly significant association between vasa previa at delivery and a history of second-trimester placenta previa.
Vasa Previa: The Impact of Prenatal Diagnosis on Outcomes
TLDR
Good outcomes with vasa previa depend primarily on prenatal diagnosis and cesarean delivery at 35 weeks of gestation or earlier should rupture of membranes, labor, or significant bleeding occur.
Morphological anomalies in the placentae of IVF pregnancies: preliminary report of a multicentric study.
TLDR
Macroscopic characteristics of 100 fetal adnexae from pregnancies obtained by in-vitro fertilization and embryo transfer (IVF-ET) were compared with data for normal pregnancies taken from the literature, finding placental morphology was normal and the insertion of the umbilical cord was frequently abnormal.
