Vasa previa and extreme prematurity: a population-based study

Prenatally diagnosed vasa previa: association with adverse obstetrical and neonatal outcomes

“…4e6 More than half of the neonates included in this study experienced complications related to prematurity, whereas 42 infants had no neonatal complications after delivery. Although vasa previa alone has been found to increase the rate of extreme and very premature delivery when compared with unaffected pregnancies, 11 this rate is higher than previously published data and is important for patient counseling.…”

Placental and Umbilical Cord Anomalies Diagnosed by Two- and Three-Dimensional Ultrasound

“…Perinatal survival rate is dependent on appropriate prenatal diagnosis and improves from 72% versus 97% when vasa praevia is detected antenatally [ 49 , 50 ]. Even if a correct prenatal diagnosis occurs, almost 70% of newborns receive NICU treatment due to the complications of prematurity [ 51 , 52 , 53 , 54 ]. Transvaginal ultrasound and color Doppler ultrasound are the gold standard diagnostic modalities [ 53 ]; however, due to the low incidence of this condition, there are no population screening protocols, and the screening approach is indicated only in high-risk patients [ 55 , 56 ], such as low-lying placenta/placenta praevia, velamentous cord insertion, ART and multiple gestations [ 52 ].…”

Vasa previa: A rare obstetric complication–A case series and a literature review

“…A population‐based study showed that pregnancies complicated with vasa previa tend to deliver preterm and face a higher prematurity risk than those without vasa previa 35 …”

“…A population‐based study showed that pregnancies complicated with vasa previa tend to deliver preterm and face a higher prematurity risk than those without vasa previa. 35 Nonetheless, the authors did not report the indications for cesarean sections. However, the available data and another systematic review and meta‐analysis also confirmed that the patients with vasa previa tend to deliver preterm, and rates can even increase by up to 81.9%.…”
