Vasa previa is a rarely reported condition in which the fetal blood vessels, unsupported by either the umbilical cord or placental tissue, traverse the fetal membranes of the lower segment of the uterus below the presenting part. The condition has a high fetal mortality due to fetal exsanguination resulting from fetal vessels tearing when the membranes

To clarify certain frequency of vasa previa using ultrasonography.Umbilical cord insertion site were examined prospectively by the ultrasound during first trimester in 3647 cases between 2006 and 2011.10 cases (1: 365) of vasa previa were found. All cases with vasa previa at the delivery had been diagnosed as a lower cord insertion in the uterine ...

Prenatal diagnosis of vasa previa
The Journal of Maternal-Fetal & Neonatal Medicine, 2014Vasa previa is a rare condition in which unsupported by the placenta, umbilical cord blood vessels runs within the placental membranes between internal os of the cervix and presenting part of the fetus. We report an antenatal diagnostic procedure and management of a patient with low-lying placenta and velamentous cord insertion near to the internal os ...

Descendent migration in vasa previa
Journal of Medical Ultrasonics, 2014‘Placental migration’ involves the translocation of the placental site to the upper uterine segment in the second and third trimesters [1]. Since the uterine isthmus is usually closed during early pregnancy, subsequently opening with advancing gestation, this phenomenon is thought to strongly involve placental migration.

Obstetric Anesthesia Digest
(Obstet Gynecol. 2023;142:503–518) Vasa previa is defined as unprotected fetal blood vessels that run through placental tissue or the umbilical cord, either over or in proximity to the internal cervical os. The exposed nature of these vessels presents a significant risk of tear or rupture during labor or after amniotic membrane breaking ...

The umbilical cord is the fetal lifeline and is the vital link between the fetus and placenta. Various abnormalities are observed in morphology and pathology of placenta. Variations in umbilical morphometry leads to neonatal morbidity and mortality. Vasa previa is one of the insertion anomaly of umbilical cord.

Management of vasa previa during pregnancy
Journal of Perinatal Medicine, 2014Abstract In order to prevent fetal mortality due to vasa previa, it is neceesary to obtain an antenatal diagnosis and perform elective cesarean section prior to membrane rupture. Under present circumstances, management strategies for vasa previa depend on each institutional policy. In our institution, patients are not routinely admitted,

Diagnosis of vasa previa requires a high index of suspicion. Vasa previa must be included in the differential diagnosis of all cases of third trimester bleeding. When pulsatile vessels are palpated preceding the fetal vertex, vasa previa should be considered along with cord prolapse.
